how to bleed coolant system 3.1/3.4 liter

[@davidmaithya9423]

Hey Joe, today I took my car in to get looked at for a transmission problem, and when I got it back, it started overheating LITERALLY less than a mile from the mechanic shop, and it went on like that, hovering a notch below the deadly red zone, forcing me to make about 5 stops to let it cool on my way home from the mechanic, a distance of 3 miles!!! So I went on an Internet search, and came across your video. Your video totally saved the day. YOU, my friend, saved the day!!! I followed your instructions to a T, and voila!!! My car is not overheating anymore, hell it ain't even getting anywhere past the middle point. In other words, it is within specifications as far as temperature goes. You deserve a golden crown of honor!!! Thank you very much for posting such a helpful video!!! For those of you that have an overheating problem, try this because IT WORKS!!!! It saved me a lot of money I would have given to those good-for-nothing mechanics that would've probably given me an incorrect/ripoff diagnosis!!! Thank you Joe!!!!!

[@JoeTheAutoGuy]

your welcome, glad it worked for you!!

[@kpdvw]

Thank you; use a funnel to fill the radiator and fill the overflow/coolant capture reservoir as well! Placing a rag around the bleeder screw will help to soak up coolant and cut down on exhaust manifold steam!

[@pinknova1301]

Thank you so much for posting this video I am six months pregnant and I’m just now learning how to really do different things to my car and I put the water pump in which was crazy difficult for me but I was able to do it and I could not believe the system with it off I didn’t know I had to turn the ignition on so you gave me the tools and the info that I needed thank you please make more videos with this model vehicle

[@dopeymark]

This is the best I've seen so far you can't believe the trouble I have been through. I bought the vehicle used and I couldn't figure out what was going on. It turns out someone had sheered off that little 7 mm bleeder and it looked like just a 10 mm screw. I bought the proper screw and bleeder on Amazon yesterday for 8 bucks. What a hassle.

[@Name-me1dn]

How did you remove the broken bleeder screw??

[@STRUGGNUGGS]

I thought the bleeding proces was done sooner than it actually was, thanks for taking us through the whole process.

[@guylambert117]

Had no heat after I flushed my radiator, your video saved me a mechanic bill....thanks

[@curtisswhite8805]

Thanks Joe. I've been fussing with my 2001 Chevy Venture for three weeks. Had the thermostat changed and it kept over heating. I didn't even know of the bleeder valve. Learned them. Didn't know that I could bleed the system while the engine is running. I didn't want to take it back to the same mechanic so I have been attempting it myself. It's working. You have my gratitude!

[@JoeTheAutoGuy]

Oh definitely need to bleed the system anytime you expose it to air besides the radiator cap

[@JJRD222]

I did the water pump and bled the air from cooling system, went for a drive and everything was good. When I stopped I could hear bubbles entering the overflow... The next time I started it started to over heat again.. I've had to repeat process many times now.. what ammo missing?

[@freshwatermechanic]

@@JJRD222 did you get it handled ?

[@JJRD222]

@@freshwatermechanic that engine ended up having a leaky head gasket and has gone from my possession.

[@janetannehale]

FINALLY I ONOW WHERE THE BLEEDER VALVE IS LOCATED AT!!! THANK YOU SO MUCH!!!! I TRIED TO TELL THE MAN IN MY LIFE THAT BECAUSE WE HAD TO ADD FLUID WE NEEDED TO BLEED THE SYSTEM CAUSE I READ IT IN THE OWNERS MANUAL AND JE ARGUED WITH ME ABOUT IT?!!!!! I COULDNT FIGURE OUT WHERE IT WAS AND EXACTLY HOW TO DO IT. UNFORTUNATELY THE OWNER'S MANUAL IS VERY VAGUE. AFTER STRUGGLING WITH THIS FOR OVER A YEAR NOW I CAN FINALLY DO IT MYSELF AND NOT HAVE TO DEPEND ON AMANDA HELP ME DO IT. I THINK YOU MY CAR THINKS YOU YOU'RE A LIFESAVER!

[@hercsurf]

Joe The Auto Guy...this tutorial kicked ass for me.. I do not know much about cars but am beginning to learn just out of curiosity and cheapness. My son has 1998 Century that was my grandmothers and only has about 60k on it...it is not a great car but gets him from a-b plus a good car for a 17 year old kid. It tends to overheat and loses heat inside. My mechanic charged me $80 bucks last time to fill coolant. bleed etc . Its been so cold here in NY that my son didn't want to drive it because he had no heat. This weekend it was warmer so I went out, used this video, and boom I had full blown heat going on. I know to those who may know cars it seems simple..but for guy like me, learning how to fill, bleed, etc it was awesome. Thanks!

[@emmettturner9452]

You never bled through the first bleeder. There is a pipe for de-icing the throttle body which comes straight up from the water pump near the radiator fill cap. There is a bleeder at the top before it goes off to the throttle body. You need to loosen that bleeder while you fill until you see coolant coming out of the bleeder. Squeeze the upper radiator tube and burp the water pump bleeder again and again while waiting for the thermostat to open. The thermostat housing bleeder is the only one you show here but if you don’t bleed the other one first you may have a big air bubble that prevents or delays the thermostat from opening.

[@charlesdowns1691]

my car was running hot usually on open highway where you may think it could draw in more air and cool down. nope. I had air pocket in cooling system and low coolant when I got car. I also decided to replace coolant temp sensor. it would heat up to 260. max on gadge. scary as xXxX. Pontiac Grand Prix.3.1. after I replaced sensor and added fluid and got rid of air pocket. wow.. I had good heat+ no overheating at all. even does good on heavy load up hill. 3.1 century engine is in car. these engines are fairly strong and fast imo. if maintained. I've added a ecm and maf sensor also. the car runs very good now and I was told it was a junk pile and needed a new engine. duhh not. thank you for this helpful video sir.

[@JeffreyStrader]

Joe you ARE THE MAN! Wife's 98 Buick Century 3.1 is having over heating issues. After watching your video you confirmed my suspicions about it being airlocked...THANKS BROTHER!

[@JoeTheAutoGuy]

Jeffrey dontyouwish thanks for watching glad i could help

[@donaldyaya06]

JoeTheAutoGuy at the end what is the piece called that you said not to mess with

[@chaplainand1]

Thank you. Just bought a 2000 Pontiac Montana - very little heat. I'll do this before anything else to see what's up. I'll post again about what I find. Blessings to you and yours.

[@kristingregory2681]

one question is rad cap on off or in vent position while bleeding

[@wyattandwill12]

My 1999 Oldsmobile Cutlass's either OEM, Haynes manual or both said to attach a 1/4" hose to the screw. That would help with the bad squirting and the coolant leaking. Remember to keep it away from the hot places.

[@bihlover80s33]

Hey Joe. I replaced the thermostat. Now, I still do not have a heat in my oldsmobile silhouette. When I was checking coolant level I finally opened the radiator cap and antifreeze came out. I let it go till its stoped. I saw you put some coolant in the radiator that's the level , right? Is it the way of edding and checking coolant level? Even after edding some coolant indicator light came up says " check coolant level "" . How to do it right way to turn the indicator off?

[@JoeTheAutoGuy]

do not touch the bleeder valve on the left above the water pump, this will cause the coolant to purge like old faithful and cause burns to you

[@emmettturner9452]

Only if you are doing it wrong. The one at the water pump (left) is the one you bleed cold, but I still go back while bleeding the one at the thermostat housing (right). Once the thermostat is open and everything is hot/pressurized it will just squirt out the side. Though it could be at any of 360°, the bleed hole is still on the side. You shouldn’t be taking the bleed screw all the way out for it to squirt out the top. Regarding the temp gauge markings: The Pontiac Montana/Oldsmobile Silhouette have a tachometer that the Chevrolet Venture doesn’t have, despite being that same van. That means they had to fill the empty space on the cluster with a bigger temperature gauge. Even with the smaller gauge, my Montana has 260°F at the top and 160°F at the bottom. That means you get exactly 100° in-between, so half-way is 160°+50°=210°F. I know it is accurate because just above half way is exactly where the water boiled when I did a coolant flush with water and cleaner (212°F). Furthermore, that makes the 1/4 mark 160°+25°=185°, which is the exact spec for the stock thermostat. Sure enough, my thermostat opens up at exactly a quarter of the way. TStat housing bleeder starts shooting pressurized coolant and the upper radiator hose gets super hot. I don’t know if this translates to the gauges without numeric markings but if your thermostat opens at a quarter of the way then that’s 185°F, half way should be 210°F, 3/4 should be 235°, and all the way should be 260°. Of course, you can’t confirm this if you are having a problem with a stuck thermostat like I was but it’s good to know going forward.

[@USArmy91222]

joe, could you please explain why you should not touch the other bleeder screw? 9:48

[@juanpalomo2732]

esinde no aselera como es

[@skillzorz101]

I think it may be for the AC, but I'm not sure.

[@masterdebater5098]

I am assuming this will fill the pump with air..

[@ThoughtWave64]

I am wondering the same thing...why should we avoid that bleeder valve? Further up I read this from Joe: "no problem, that bleeder is for the initial fill, no pressure or heat , and coolant system is empty. you open that one and once fluid comes from it close it down , do not open it under any pressure or it will blow and if the engine is running it will blow like old faithful"

[@robertmartin2190]

its on the waterpump

[@jessewoof2591]

Just found your video, waiting until I have the money to buy some anti-freeze and going to try to follow your instructions, wrote them down in order so I hope it works. I am not a mechanic by any means. My wife's aztek has been down for 14 months now while I taught myself how to change the thermostat, heater core, radiator, all the hoses, and the water pump. It is our only vehicle so I hope this works. If it does you will not only get my thanks on here but I will be throwing your name and link out on facebook too. If it doesn't work, no worries, I won't give you a bad review, I am not like that and don't blame others for my problems but you will get some promotion from me if you make my wife's Aztek work finally.

[@JoeTheAutoGuy]

Jesse Woof glad to be of help, what was the initial reason it was down?

[@jessewoof2591]

Not blowing heat and overheating. Took 11.5 hours to go 23 miles. Replaced thermostat 3 times, then ask in one shot did thermostat, radiator, heater core, water pump, all hoses, cleaned throttle body and coolant passage of throttle body. Took most if the year to learn how to do all of that but got it done. Was originally trying to bleed with both bleeders until I watched your video. Wrote down ask the steps in order, have watched it 3 times and after I get some antifreeze on the 3rd I'll watch it one more time before I go it and tackle it again. Hoping after all this work it's not the damn head gasket. I have white smoke in start up but then it clears, I don't see or smell coolant at the exhaust, no coolant in my oil, and haven't noticed any oily film in my overflow reservoir do I am hoping it just needs to be bled properly.

[@richardg4965]

Joe, I am also perplexed by your comment about not touching the pump housing bleeder valve. If it causes such a "very bad day" by using it for what it is intended for, could you please elaborate a bit? Some of us older shade tree mechanics might want to or need to know.

[@JoeTheAutoGuy]

no problem, that bleeder is for the initial fill, no pressure or heat , and coolant system is empty. you open that one and once fluid comes from it close it down , do not open it under any pressure or it will blow and if the engine is running it will blow like old faithful

[@TyRC12]

Do you mean the coolant will blow out like old faithful? Sorry I'm slow. I was looking for the same answer

[@michael88h]

How long you have to do it. Ive been doing it almost 30 minutes and its nothing but air atm.

[@andynorris14]

Just had to do this on my 95 grand prix after replacing the heater core. What a pain in the ass that was. Great video. Thanks man!

[@kevenstites5455]

What happens if you touch the other bleeder? Cause you said causes a bad day

[@TheWorldWarrior]

I opened it and it literally shot coolant so high up hit my hood and splashed everywhere so basically don't use that one.

[@justinmojica1977]

Look at the way your Radiator cap was designed for that specific vehicle. Every time you pour Coolant into the Radiator cap without a funnel; your practically spilling Coolant all over the place. Brilliant Engineering.

[@justinmojica1977]

True. How could I have forgotten to mention that most important rule.

[@JoeTheAutoGuy]

homes24 it was previously flushed with green coolant, completely fine if your running all the same coolant , but yeah for everyone do not mix coolants its a huge no no.

[@joenavarro9317]

What happens if you mixed a lil bit like half a glass or so ? Damn O Reilly's worker gave me the wrong one glad my 2000 Pontiac grand prix didnt need much but now my car is over heating and I dont k ow if that's the problem my fans are not working for 1 gonna check if the motor on them are still good but back to the coolant can I do what Scott did and flush it out with water ?? HELEP lol thanks

[@kevinemmers9424]

DexCool and green stuff should never mix. Together, they form a sludge that clogs cooling passages, resulting in poor coolant circulation. This can lead to head gasket failure or intake manifold failure. These engines do just fine with the green or the red. Just never a mix of the two in any portion.

[@DamonCogan]

I took my car to jiffy lube to have my system bled and they used the other valve that you said in the video not to use. The next day my car over heated so bad that it blew a head gasket. Thank you for this video on the RIGHT way to bleed a coolant system.

[@ednja]

While you're loosening the bleeder valve, is the radiator cap turned on all the way? If so, does the coolant get sucked out of the overflow tank, into the radiator, to displace the air that is bled out?

[@juliusterrell205]

This video was helpful in how to bleed air from the coolant system. After the temperature reached 225 degrees he added more antifreeze to the radiator. You don't want to take the radiator cap off the with the car hot. You can get burned. Let the car cool down before opening the radiator cap.

[@debracrume1259]

P

[@debracrume1259]

P loop p poo

[@chasstone5048]

I think he meant after the bleed process...tip off when cooled. He jumped around but yes on get radiator pressure 1st but breezed thru that on how. Then if a car wasn't getting radiator pressure he passed over. Say the pump or loss of pressure..nope..just showed pressure on cap..but yes to bleed the system that's how.

[@krr711]

Very thorough and helpful video. The details are important in case you have a very stubborn coolant system. Thank you very much!

[@JoeTheAutoGuy]

+krr711 your welcome thanks for watching

[@baggy-vitamin9166]

Not the left side valve, why is that? Some other videos show usage of both valves for a full bleed.

[@codyshuey258]

What does it mean if coolant stops coming out of the bleeder all together, and its just steam?

[@Mezgur]

someone please buy this guy a funnel

Half to bleed when changing the radiatior and hoses and thermostat?

[@titomartinez596]

U should always make sure u dont have air in the cooling system

[@Daize504]

Wait a minute so you can use the green coolant for this engine type? Cause i use dexcool and its the first time I've ever got smudge lookin shit around the radiator cap

[@azureblue29]

You should stick with Dexcool. Switching or mixing them leads to lots of problems. I speak from experience.

[@Tshizzle42o]

If you FULLY flush the dexcool out you can use whatever you want. Dont mix different colors of coolant or bad things will happen. Apparently the orange universal coolant works with dexcool. I hope thebpeople from the 3 parrs stores in town know ehat they are talking about cuz im doing this with my impala right now and i only know the coolant is orange. No clue if it is universal or dexcool...

[@Davo983]

[@jamesonlongfellow3130]

Does the coolant blow-off hose on the resivoiour connect to anything, or does it just hang there? It's a 2003 Malibu 3.1

[@trelocsta594]

I have an impala 3.4 and I have two bleeder screws. one is above the thermostat housing, and the other above the water pump. do I bleed the one above the water pump as well?

[@larrywilson1786]

To burp the system as easily as possible, would it help to lift any part of the car up in order to force air toward the bleeder?

[@RobertoSantiagoRodriguez]

[@LittleLadyk2002]

Have a 2006 equinox 3.4l. Is this bleeder valve located on the water pump? Is it on the water pump on these cars. Bf wants to confirm before proceeding. Thank you

[@petianovakova313]

How do you drain the coolant completely? I understand there are 3 different drains, 2 seperate from the petcock, is that correct?

[@JRNelsonSr]

Turning the heat on doesn't help in my case because the heater fan, rear defrost and cruise control are disabled in recirc (fuses are good). This seems to be tied to the coolant level but is getting more common as time goes on: lately it has to get real cold to fire up the heat (and even that is flaky). How do I get around that?

[@topherd1011]

Mine only has the one bleeder screw with only an expansion tank cap. Manual says to crank up and run to operating temp and then open the bleeder screw you just said would give us a hard day.. Does the bad day apply to me and my vehicle? Lol. Thanks.

[@Samestori214]

thanks for the video. the info at the end was GOLD! I was just saying that you didn't say anything about the 2nd bleeder screw. then you said don't touch it or very bad day. WHAT about when the WATER PUMP is changed? do you bleed the 2nd screw? Thanks

[@DoozCoop]

[@PSTLNC2]

Joe, great upload. I did this to my 2000 Pontiac Montana after I did the thermostat. Bled system but still did not have heat. Come to find out the heater bypass pump was seized up. Took the pump off and disassembled and cleaned the remnants of the Dex-Cool that used to be in the van. I will agree with almost every experienced mechanic out there that says that Dex-Cool is garbage. It was actually like clay in the pump housing. Cleaned it out and pump spun freely and then I had great heat after bleeding again for about 10 minutes.. Again thanks for the upload.

[@bradapierce1980]

Question: I bought a car from a guy that has the 3.4 he had a leaky water pump and kept putting green antifreeze in it and its suppose to take the orange. How do i get the green out of the block to put all the right kind in It. I was told mixing the 2 isn't good.

[@JoeTheAutoGuy]

Flush it out , pull a heater hose off and the lower radiator hose and then use water and flush out, then pull block drain and drain, then use distilled water and DeX cool or prevent mixed DeX and fill and bleed system

[@kallestofeles]

Got 2001 S-type, no heat coming. 2 bleeding valves: one for engine cooling, other one for heater unit. Both hot. Engine cooling valve filled nicely but the other one I just can keep on bleeding for hours, coolant comes out periodically... but when pressing on the pipes, it comes out nicely and no air seems to be inside the system. Yet, only cool air. When bleeding for 20min, I get 1-2min of hot air until I close the bleeding valve... no leaks or anything. And not the heater unit. Got any ideas?

[@timkluna5185]

Thanks for the great video. My van was over heating and after bleeding the coolant system it never gets over the first line on the temp gauge. I was surprised how much air was in the system. Thanks again great job.

I thought you weren't supposed to remove the radiator cap while the engine was running? Thought it'd spray coolant and burn you?

[@cabrera757]

My 01 Malibu 3.1 only has one bleeder valve by the water pump. Do I open that valve or just leave the reservoir cap off until it bleeds the air off since it's up higher than the radiator and hoses?

Antonio Cabrera on thos just leave the resivoir cap off

[@DavidBuckley79]

I have a 03 malibu with the 3.1 it only has the bleeder above the water pump should I open that one or just the tank? You've said no but I've heard yes. Anyways I've tried both to no success.

my pontiac Grand GT 3.4 Am v6 ram air doesn't have a bleeder screw at the thermostat. What do I do ?

[@InspiredGuitarLegends]

Great video and thanks. What if I'm getting nothing but air out of the bleeder? Fluid level appear to be full A the end you mention not to touch the water pump bleeder, why so?

[@JoeTheAutoGuy]

InspiredGuitar1 bleed the system by opening the radiator cap (when its cold) and top off coolant, run the car at a accelerated idle about 1000-1400 rpm as the car heats up the antifreeze level will rise and when it gets to operating temperature or close shut the radiator cap and then open the bleed valve if it continues to run hot to get the stubborn air out. when it runs in the normal range then wait for it to cool down then open the cap (COLD) and top off coolant , if you touch the other bleeder it could blow off and burn you i did it once and it blew like old faithful

[@charlesdowns1691]

what was the other bleeder sir? the bad day bleeder? I just wanna learn. thank you.

[@charlesdowns1691]

I think the bad day bleeder was water pump bleeder. correct? I just read a comment. ouch. lol

[@wolfqueeniloveyouall725]

car stop overheating I noticed the first few bleeds my a/c went from blowing cold to blowing hot after I kept bleeding it. (had it at hot like u stated to have it on in the video)

[@youtubeaddict2018]

I noticed you opened your radiator cap to add water after you opened and closed the bleeder valve. Is that why water didnt spray everywhere when you opened the cap? Can you just add water to the overflow canister instead?

[@JoeTheAutoGuy]

the cap was on the vented position so the system never built pressure . when filling a non degas bottle setup you need to fill up the cap for the initial fill and bleed

[@prolificgfx891]

do you leave the radiator cap open?

[@JoeTheAutoGuy]

yes the radiator cap should always be open when bleeding the system the bleed valve i touched just gets some of the air out of the intake faster

[@rcont75]

[@joebartoszek1835]

in the summer. would having air in the system cause over heating? i just replaced my thermostat and was hoping that would fix the problem but still boils over:/

air in the system will cause overheating needs to be bled after any service that opens the cooling system ( anything besides the cap)

on what car you were working on?? I have oldsmobile silhouette 03. No heat, no a/c. Also, no overheating. Do I have the same pr8blem as your car or its just a thermostat. I em early bird, so I am sorry , but I just wanna go out and replace my thermostat but it's still dark. 5:30 am . Its cold and rainy but I need to fix it, anyway. Thanks for this video.

[@JoeTheAutoGuy]

i wouldnt go replacing the thermostat unless your car is not warming up to temp. check the coolant level before attempting repair ypu might just be leaking down, Air conditioning is not related to the thermostat

[@hasaanbhutta]

Hey Joe.... 2005 Chevrolet venture.... I can't get enough heat. It's starting to get pretty come here (-17 c) so heat is a must. The fan works fine but no hot air for me. Any ideas ???

[@JoeTheAutoGuy]

Hasaan Bhutta might be low on coolant and or air in the sytem, if you have rear heat it can be an issue with air trapped in it that can be hard to get out, might need a spill free funnel to run and get it all out

[@jessrayner4438]

great vid. son took car to have oil changed about 2 weeks ago now we have the temp issue. not sure if oil place may have added coolant or what. figuring probably thermostat but gonna try bleeding first. do you have a vid for the tst

[@JoeTheAutoGuy]

Jess Tenca unfortunatly no but its not a fun one also check the tank cap common problem

[@mychaldavis25]

I have a 2005 chevy impala LS I flushed the radiator, changed the thermostat and my car temperature still raises when im at the stop light. Plus my fans do work they come on when they are suppose to. My question is do I need to bleed it?

[@JoeTheAutoGuy]

Mychal Davis if still over heating check if there is air in the system if so possible small leak , low coolant, headgasket , the list goes on hard to say what your problem is with little info. what engine do you have in it ?

[@mychaldavis25]

It's a 3.8

[@wvscotsman]

On mine i am not pulling coolant from the reservoir tank. I paid a guy to do the lower intake manifold gaskets and head gaskets, It is running a little hotter and the heat is not what it seems it should be in the cabin. Will air also cause it not to pull from the overflow tank?

[@tsfyootwiin]

wvscotsman That’s what mines just did. And was told it could have air in the system. I had my head gasket done and after coolant came out from the overflow tank and started to overheat.

[@saulgarcia407]

Just change the water pump on a 1998 Chevy Venture, but I have the light saying Low on Coolant, but the the Radiator and the reservoir are full. What do you think? Should I do what you did in this video. Well I'm going to do it, and thanks for the video.

[@JoeTheAutoGuy]

saul garcia make sure the sensor is connected in the resivoir bottle

[@saulgarcia407]

thanks for the reply, and what sensor are referring to? and the weird thing is that the light turns off and comes on. aand yet I open the radiator and is full. Thanks again.

[@JoeTheAutoGuy]

saul garcia there is a sensor in the bottom of the reservoir bottle that is the sensor that is triggering low coolant to come up

[@saulgarcia407]

thank you , How can I repay you for the help?

[@UFOGHOSTHUNTER]

saul garcia tap where the connector is on the sensor and it should float back up and the light turns off.

[@blowfishofdoom]

Going to take a wild guess that if a hose clamp failed and i had to put the hose back on I have to do this?

[@DREDFIRE14]

Yes

[@DragonL33t]

My 2002 Malbu LS Only has the one bleeder by the water pump. Mine is the pressurized system. I tried just bleeding mine by removing the cap and getting it warmed up by putting some rpms on it and it started spewing coolant once it got hot... Not sure what to think of this.

[@JoeTheAutoGuy]

was it over heating during this?

[@DragonL33t]

It was a tick over the half mark on the gauge. Fans wont turn on unless the ac is on. I dont know what is considered overheating on the gauge meter besides the red mark.

[@barbmonike7589]

JoeTheAutoGuy Replaced water pump and thermostat but have very loud whistling sound. Is it due to still having air in the system?

[@davidsolis7267]

Is your rad fan blow toward the engine or toward the radiator? All 2000s gm impala models . Let me know thanks

[@justinv3080]

David Solis the radiator fans are behind the radiator and pull air through the radiator and also blow air onto the front exhaust section. That's pretty much how most are setup, the fans have to blow or pull air towards the engine otherwise they would be fighting incoming air as you move down the road. The radiator fans not only cool the radiator but also have some effect of air cooling on the engine itself.

[@chadwickvallette1264]

So for the bottom bolt on the thermostat housing on a 3.4 in a 01 aztec to get rid of the difficulties reaching it bending wrenchs an braking my hands i took a look.. REMOVE THE THROTEL BODY AN YOU HAVE FULL ACCESSES TO THE BOTOM BOLT.

[@JoeTheAutoGuy]

Nice tip! Thanks for sharing!!

[@cam1317]

Hey, just like Dyllon Galan I have an 02 malibu base model and it only has the bleeder by the water pump (pressurized reservoir as well; no rad cap); is it still inadvisable to use that one to do a bleed? Not sure what my other options are..

[@JoeTheAutoGuy]

cam1317 no do not use the pump bleed the reason i explain in the video is for stubborn air pockets. but in the pressurized reservoir just run the engine at an accelerated idle (1200-1700 rpm) to warm the engine up until the thermostat opens and then just top off coolant as needed

[@hardworker2877]

hi awsome video. my mom's got a 2000 Monte Carlo. and it has no heat at all. the heater core hoses are Cold ice cold but then the lower will get a lil warm not hot .. but not temp change?? and ideas. winter just hit Chicago. need help

[@stefanwinter1377]

It says here on the radiator of my 3.4l firebird that it has a special filling procedure. What's up with that?

[@JoeTheAutoGuy]

What year fire bird do you have

[@stefanwinter1377]

@@JoeTheAutoGuy 94 3.4l automatic.

[@manuelloera6564]

I was working on a Chevy venture with the 3.4 and the needle kept going past half,and fans weren't turning on unless I turned the a/c on..why???

[@JoeTheAutoGuy]

something is wrong with your main fan, the secondary fan turns on when your ac is activated so your main is probably never turning

[@jonathanyates5198]

Coolant temperature sensor

[@davidyakle5651]

What do you do when this doesn't work? I followed this procedure at least a dozen times and only got a mess on the garage floor. seems ok for a couple of miles then no heat and overheat. I pressure tested the system and it held 12 pounds for 24 hours. still the same problem. I replaced the intake gaskets after they failed and can no longer use the car. Any ideas?

[@JoeTheAutoGuy]

did you replace the thermostat, many issues are with the water pump as well, ive had a few that have been head gasket issues and will only show a leak under pressure of combustion just a few things to look into if your still having issues
