Chevy Blazer Intake Gaskets Replaced & Cooling System Rebuilt

[@dessadgirl9778]

Thank you this video was much needed it's hard to find blazer videos

[@JustBrianMusic]

the trials of a home mechanic, i changed the tstat yesterday, hoping i dont have to dig this deep for a long time, good luck!

[@Rock_Reggae_Riff]

Great video. my blazer has the same leaky intake gaskets, I plan on fixing it soon. I used a universal pulley holder and a big wrench to remove the fan when I needed to replace the water pump. it took a few minutes to remove the fan.

[@tigerace351]

Great video. Very well filmed and very helpful to anyone looking to do this job.

[@asplicerdude]

Dexcool clogged my radiator, caused overheating. Changed radiator. UPGRADED to electric fan. Now coolant leaking from manifold. Thanks for video. I would highly recommend electric fan upgrade

[@eyetotheworld]

asplicerdude Thanks man! The DexCool clog thing is a MAJOR issue that resulted in GMC loosing a class action lawsuit for knowingly utilyzing a formula that created issues after an average amount of time.

[@yambo59]

Soon as I got my 2003 S10 LS 4.3 with only 7,200 mi. I heard about dexcool problems, so before it had a chance to get this bad I took it to a professional radiator shop where they recommended I do a chemical back flush of the whole system getting rid of as much if not all the dexcool, then they replaced the thermostat and changed the coolant to regular green glycol coolant. I now have over 86K on the engine and the cooling system has been trouble free -- so far, but I do have a mysterious vacuum leak and I fear its the intake gaskets. These trucks are also known for heater core problems and thats a huge job on these trucks requiring the whole dashboard be removed, a real PITA. These repairs are my next fears, a radiator and water pump swap would be a walk in the park compared to the heater core and intake gasket jobs.

I'm not sure if someone else mention this but i got news for you brother. You were officially a mechanic within the first 6 mins of this video. (Other than the mic issue) great video bro. P.S. Shout out to the real mechanic's that's keeping those annoying family members and personal vehicles running all these years, whether on the curb in front of the house or in the ally's...LOVE...🤩🤩🤩😝😍

[@josephnemish5869]

Great video sir. I plan on replacing my gaskets and basiclly everything you did as well next month. Thanks alot for the in site

[@rubal626]

I got a slight manifold leak that only leaks in the morning. I am sure i will have to go through this in the near future. i already replaced my radiator and hoses along with the flush so that should save me some dollas. But all in all it will be a good learning experience for me as im sure it was for you. These videos not only give people a heads up but also shows that you can work on your own vehicle without paying a grease monkey $75 per hour. $75 x 18 hrs = $ 1350 you saved. Right on! thanks man!

[@eyetotheworld]

rubal626 Thanks Rubal! I hope that it is working out for you. Morning leak only sounds wierd, but, as things heat they expand. This could be causing a seal once your engine "warms up." Good luck, and take it easy.

[@x-man5056]

Don't dis mechanics. They don't pocket $75/hr., not even half. If they brake a bolt or job takes more than standard hours, out of their pockets. If it leaks still for some reason, they do it over for free. They spend all day long bent over cars that owners can't even bother with prevent maintenance and have to work on grimy shit all day, everyday. Show some respect. It's a tough, honorable profession. There are bad apples, just like doctors, lawyers, bankers and whatever you do.

I have to fix the same problem on my Blazer. Thanks for this great video !

[@larrygonzales7410]

Just was givin a 2000 s10 and never even looked under the hood. Truck runs like a top but my cooling system is full of sludge. So it'll take a while a alot of patience to get it all dialed up. Awesome video

[@martygp266]

No idea if this will reach you, but did you ever figure out what the cause of the sludge is, similar scenario. How’d it get fixed? Thanks

[@phoenixgaming454]

[@JeremyBorumComposer]

Thanks for that link at the end, I'll check it out. I'm getting some knocking/clicking noise after overheating, so I think I'll need to get at least this far into the engine to find out why.

[@exmerion]

Guys if you are thinking about doing this don't wait! Mine was just a very minor leak and one day on the way home my engine sputtered out. The gasket finally gave way and all my coolant Poured into the lifter valley. Huge PIA to clean up all the contaminated oil plus you could blow your head gasket at the same time.

[@x-man5056]

Mine was loosing coolant but I could never locate the source. Then one day on a short trip to the store motor got up to 240 degrees. I had coolant in my drivers door jam.

[@brandonseifert8527]

A trick to remove the fan is to put your wrench on the bolt (while the fan pulley is still bolted to the engine) and hit the wrench with a rubber hammer. It’ll shock it loose a lot of the time

[@sweetkellymay]

To take off the fan. Keep the serpentine belt on. Put a large adjustable wrench on the big nut. Get a big heavy bar. Smack the wrench as hard and as fast as you can, "counter-clockwise" This will break it loose..

[@x-man5056]

Dead Blow Hammer, not heavy bar

[@jamesfair9751]

They also rent out the tool to hold the pulley while you turn the fan nut.

[@rh6108]

thanks for the video. i have the exact problem on my blazer right now. looks difficult for an inexperienced person with no garage.

[@eyetotheworld]

Thank you Sir!

[@bg147]

I had the same issue with the alternator. It appeared to be held in the bracket with locking fasteners of some sort and I ended up removing the entire bracket with the alternator still attached. What it really needed was to be pried out with a pry bar and removing the bracket was a waste of time..... but rewarding, not really.

[@apdcarson4490]

the fan clutch nut is easy if you use a hammer on the wrench,make sure its the same rotation as the motor,and one quick rap,while the belts are holding it for you from moving,and it will spin right off.Ive done it at least a hundred times.

[@eyetotheworld]

Yeah, that part of the breakdown was actually the most time consuming/difficult for me.

[@dontrompas1312]

👌 Awesome. I like love my blazer. Wouldn't trade it for a newer vehicle. I find it easier to work on older models..

[@tnickells]

Excellent video for the amateur back yard mechanic. Both my 2002 Pontiac Gran Prix and 2002 Buick Century have the exact same problem. I opted to trade both cars in. Too much work for me.

[@glennmanchester1568]

Those cars dont have the 4.3 engine

[@urbanjunglerider9229]

Great job, painin in butt but , i have to do that on my s10 because coolant leak at same spot. Thx for video

[@robertross5284]

the shroud holds the radior in place

[@steverandyl7702]

big MISTAKE. Get rid of the dexcool and go back to the old fashioned green stuff.

[@littlewazz]

the problem lies in the design of the radiator cap, when GM came out with DEXcool at the same time the radiator caps have a flaw with the OEM caps they would stick partially open allowing air to enter the cooling system causing the coolant to coagulate, get an an after market radiator cap like a Stant

[@x-man5056]

Keep the DexCool. Get a new radiator cap. Green anti-freeze not good for mixed iron and aluminum coolant passages and doesn't last as long either.

[@FireEater]

Make your own fan removal tool out of a piece of angle iron use a grinder to trim off so it will fit line up bolts on water pump mark on angel iron drill two holes on marks remove water pump bolts screw through holes back into water pump.Put a big wrench on fan nut and it will come right off. Hey good job. 👍🏻

[@eyetotheworld]

Wendy Perez Hey Windy, I'm so sorry I didn't reply sooner. I hope you've resolved the problems. But for the sake of answering, I would recommend changing the water pump if you haven't. While not neccesary they are "designed" (not really, but seem that way) to fail at 100k miles. Due to their low cost (

[@martinhoward1773]

When ur was leaking did it over heat and did coolant go in ur oil with the intake gasket bad

[@getsomemtb7427]

Mine is leaking at the rear drivers side as well. Now I need to decide if I want to tackle it myself or pay my mechanic. May have to go to the pro since I lack a few tools like a torsion bar and a few other minor things. I'd probably spend more on tools than parts for sure. Well...let me see how much money will persuade me to do it myself.

[@eyetotheworld]

I realize it's been a month but, do it yourself! Not hard to do, and you could buy all the parts + Haynes manual for less than a mechanic's hourly rate! Also, major since of accomplishment.

[@BigJZ86]

How is the engine running today... I'm thinking off replacing head gasket in my engine... It went last week.

[@eyetotheworld]

Green Gold Hey Green, it's running like a champ! Since the repairs, and a couple minor tune ups, I've gone from 12 mpg to 15mpg. Admittedly I JUST had to add more coolant, but that could be due to natural evaporation etc (as I haven't added since the repair). Take it Easy!

[@justinp8946]

It's 4.3 they can be abused and still run.

[@izakwasserman2887]

drain and flush all dex cool and run green 50/50

[@a.s.4914]

izak wasserman I've always used the dex cool in my blazer, with no problem. The problem is people don't change it on time, and it gunks up. Flush and fill on time people! No heater core problems, either.

[@MHsearchingTruth]

i'm curious how you ended up getting the fuel lines out of the way @ 4:07 , i'm alittle worried about bending or crimping them, thanks in advance

[@WizzRacing]

+Marcus Hempker The intake rotates under them, As all you need is a few inches to the right to get enough room to remove it. As he said stay away from screwing with the spider injector. That thing is so easy to screw up.

[@mariaelena78224]

I did everything you said to do. But I might of did something wrong. Now my motor wont turn. Making a grinding noise. I really need help.

[@rayysnhelll]

[@phoenixgaming454]

When im replacing the headgasket i dont have to replace all that you did right?

[@mr.joshua204]

how long did it take you to disassemble, fix, and put together the engine

[@eyetotheworld]

In all, about 8 hours... That was with 0 experience on this particular repair. I have since done it 2 more times to a buddies other vehicle (1992 F150) in which it was about 3 hours. Biggest problem with the Blazer is how compact everything is all together.

[@mr.joshua204]

eyetotheworld dude I know lol, it's a bitch just to put the spark plugs in. I had to turn a wrench into an L shape by heating it up just to get the one behind the drive shaft in

[@nicenonya3]

easy thing to do is disconnect the steering shaft for that one.

[@DS42O]

after doing this did it fix your leaks? I've got a 01 blazer ls 2dr that is now leaking coolant right above my waterpump where the intake manifold is

[@eyetotheworld]

Hey, sorry it's been a while since I logged on. It did fix it, and it is a rather easy fix at that. Just dedicate a uninterrupted weekend, and make sure you have the tools or a backup car to get to the auto parts store and you can do it!

[@supershark9k708]

So I'm about to do this is a new water pump needed when replacing the lower intake gasket

[@sensign671]

Hey Eye. Great vidio and thanks. I have heard that the dex cool may be the cause of the corrosion. with in my research some people have converted to normal glicol based antifreez/coolant and have had good results with in there GM engins. Note the dealerships always add a couple tabs of Bars stop leak pellets in a new car and every time they sevice it to inhsure there are no leaks in your GM product. I have the same problem to look foward to with my 2005 astro van. A tougher job.. Wautched Scottys detailing vid and a few others Im pretty sure I could get the job done with a little mechanicl common sence, some luck and some help from you guys with out having to spend over $200.00

[@eyetotheworld]

Scott Ensign Hey Scott, it's been a year, I hope the van is running fine. Interesting about the Bars... It makes sense though, seeing how once your factory warrenty expires things start to fail...

[@autumnmentzer3176]

Did you convert to regular antifreeze instead of the dexcool? Getting this problem fixed now and I'm wondering if we should use the dex cool that the car calls for or just regular? Thanks!

[@rR-vs9bo]

I use the regular green antifreeze on my gm motors and they do fine

[@justinp8946]

+Jesse R me too. Prestone or supertech works good

[@rR-vs9bo]

Yes, and they don't clump up like the dex cool does.

[@justinp8946]

+Jesse R agree. I've seen dexool with low milage like 80k and it leaves that nasty orange residue everywhere. My moms 06 taurus had 95k and 10 years old and the mortorcraft coolant was till nice and no residue crap.

[@HandyFox333]

Do you have to drain the radiator? Also, how did you work around not taking off the ac bracket. That's the only thing holding me back. Never mind, you explained but there's one screw I can't seem to get to for the life of me on that bracket. Edit: Went to Lowe's and bought a snub 14in wrench. $4 if you're planning on buying it. It worked like a charm if you have the right hands and arms that'll fit in the crevice without having to go under the car.

[@ryanwright1447]

Great work pal I'm most likely trading my cutlass ciera for a 2002 4x4 blazer today with a coolent leak hope it's simple and not the intake gasket 😺

[@allenhoffman2127]

I hope you timed it since you had to take out your distributor

[@fngonuts]

computer does the timing on this engine. one does need to plumb the distributor tho. one will need a live data scanner to do so.

[@omarjuarez7063]

how did you an screwed the bolt under the air compressor?

[@steventartamella454]

How did the oil look? I'm hoping its not my head gasket. Is the oil a brown color or similar? Same problem your having..thanks

[@steverandyl7702]

lastely you said the radiator is not held down by anything, wellll your missing the bracket that goes along the top of the radiator which bolts to the coresupport. Thats what holds your radiator down and with out it you will be replacing that radiator again.

[@coyoteserranoband]

Bad gasket? Does the Blazer drive with a bad intake manifold gasket?

[@BIGxJIMxSLADE]

Mine drove for several months, with coolant disappearing regularly. No drips on ground, no smoke, nothing to show a leak. It wasn't until it REALLY went, and my coolant and oil mixed, that you IMMEDIATELY know there is a problem. In the process of doing the intake manifold gasket now. I came here to get some info on removing the upper plenum. Since the lower plenum has oil/carbon in the injector area now, I was thinking of taking the lower to a shop to have it cleaned all out, as I have no parts washer/place to dump chemicals.

[@fcobob78]

Great video. Have a similar leak :( looks like a hard job. Do you need a special engine lift to take out the top part?

[@eyetotheworld]

Francisco Bobadilla Its been a year... Sorry for the delay. No, the engine requires no removal, and all of the work can be done out of the front area. Good Luck!

[@hsanc72598]

If you own an s10 Blazer/s15 Jimmy, quit using the Dexcool. Use the green one that says: For GM trucks pre-1995. It doesn't matter if your particular GM truck is not pre-1995, the green coolant won't corrode your engine cooling system. If you're currently running it using orange Dexcool, drain your cooling system, flush it a few times, clean the gunk, then use the green Prestone or the equivalent generic green coolant.
