thank you for holy language, it is rare to hear pure instructions.

[@JeS-ii6yp]

Your precision, tight shots, camera angles, clarity, and detail of your videos really makes it easy to duplicate what you're doing. You're really a great instructor!

[@1RoadGarage]

Thanks!!

[@JuanDePan]

9:11 I felt that 😂yep I’m going to be replacing mine this weekend. Your channel is awesome!

[@alphasaiyan5760]

I was waiting on him to short that clamp up under the positive cable at the alternator lol

[@davidshipulski4532]

Great video Jimmy! Best one out here. I could hardly get to my drain on my 96 K2500 sub then realized it broke off. I said well that video I watched he used those harbor freight hose/clamp pliers. Well I went and bought those. Spilled hardly anything. Great idea! Would never have known they had that! Thanks again!

[@diazmike427]

Great video, Im a fan of the channel but just one thing bro. Just for future when you use a torque wrench on an extension with a swivel base, the torque is not accurate so just be carful of that. Keep up the great videos!

[@BestLittleStudio]

Thank you for not doing an April fools video. Also, I will be doing this tomorrow, look for a thank you video to come.

[@TheEndeavoringFamily]

Just replaced mine thanks to this video... then I replaced the ground wire ends cause those just snapped off 😳 😆

[@ralphvaccaro2638]

I like that rubber gasket

[@jimbeamm36]

Great VDO. My 95 G20 Van has the same issue. Temp gauge only reads 100 , lukewarm heater. Will try this fix. Thanks again.

[@fixingwhatihave2906]

Did it work?

[@jimbeamm36]

It helped a bit. The temp gauge reads about 185 F now. But the heater barely puts out enough heat. My 1991 F150 Heater puts out 10 times the warmth.@@fixingwhatihave2906

[@BlueFlyer21]

love the fact it sticks open not closed

[@ihateads9220]

The nut 🔩 for the deep socket the bolt broke. However enough was left I could but a nut on it. I had to route my wires elsewhere so I had a ground for the tempture gauge. I have a different set up for a 1991 Chevy Silverado with the 350. I have one wire going to the bolt a easy fix for the ground wire.

[@TVCColin]

Awesome! I am getting ready to make a video for my other channel on this same subject. I have a 2000 Yukon Denali with the same issue.

[@benkanobe7500]

On an average day, when your truck is completely warmed up maybe even after a frwy run, what is your idle oil pressure and what is your 75 MPH oil pressure? I am using your truck as the "*Perfect*" truck due to the previous owner and your care. Thank you, Jimmy.

[@jameslaiola4976]

Thats exactly what happened to me. I had a stuck open thermostat. My replacement seems ok now. But when i first installed it. The new one immediately overheated.

[@brandan3776]

Thanks for the video man im a visual learner so video helped me alot keep them comming

[@arabcampers9554]

You are the best jimmy , thanks a lot I just hope you do more videos on this suburban .

[@atomicdmt8763]

Excellent: clear, solid info. more please!

[@1ruerue]

Very good step by step video 👍

[@AWIERD1]

I've just done this for my truck it has the same engine tbi 5.7 just a Silverado. I would recommend to replace the stud because i broke mine in half and couldn't extract it. I had to cut it flush with the intake and drill it out and tap a new hole. The stud was welded to the aluminum 😥 Also your antifreeze looks dirty i would flush it. The additives keep corrosion down from all the dissimilar metals in your cooling system.

[@atgoodrich90210]

Good video. Just one thing for all novice gearheads--replace those shitty factory spring things with proper hose clamps. That way, the next time you remove the hose, it'll be a cinch.

[@jimbeamm36]

About that hose clamp. The one on his engine is the proper one. It will expand when hot without damaging the hose. A screw type clamp cannot expand as temps go up.

[@richardthompson6366]

​@@jimbeamm36Yep, you are correct.

[@Therehabanddocumentationguru]

Excellent video, and excellent video quality

[@westtennesseefarming288]

It always goes up to that 195 then never gets past the point you showed in the video they must get up to that temp then go into closed loop and run steady.

[@dennisyarbrough7284]

Hey a friend of mine told me that you have to use a paper gasket on my 95 Chevy pickup along with the rubber gasket. Is he right or wrong

[@imaslowlerner]

The bugger bolt? I snapped mine now I'm having the hardest time trying to get that broken bolt out.

[@freddyv7546]

I had the same issue with my 99 K2500 pickup. After I replaced the thermostat, the temperature gage noticeably improved but it still looks like it should be a little higher. I also change the gage sensor in my quest to fix the problem but it didn't do anything. Also, the heat started working again after I changed the thermostat. The only other solution I can think of is replacing the cluster which is often malfunctioning.

[@helivesonforever]

Right between 210 and the quarter way line is normal. Mine usually runs one tick above the quarter way which is just fine. The stock gauge acutally reads a little bit low and if you use an infrared gun at the thermostat housing it'll be close to 195 even though the gauge looks like it reads lower.

[@ironlionzion2265]

Thank you

[@jamiegrasso3433]

I have a 98 suburban. It had a coolant leak. I replaced the T hose connector yesterday. There doesn’t appear to be anymore leaks but now the temperature gage is all over the place. It will go up to 230 then drop back down to 100. Then it will go back up to 200 then drop all the way to zero. My best guess is it’s the thermostat unless someone has another answer?

[@andrewsoberluv2818]

I love your vlog

[@KanyeSays]

Do all, if not, most 95 chevys oil pressure gauge fluctuate when acceleration and slowing down? Mine does, someone else told me his Tahoe does and I see yours. This a common thing?

[@AustinHarmon1994]

Kyle Marshall that’s normal on every engine with a oil pump. When a engine spins faster it also spins the oil pump faster which causes higher oil pressure. On a lot of cars now the oil pressure gauge doesn’t move because it’s not really showing oil pressure but instead it’s more of acting like a dummy gauge that just lets you know you have oil.

[@jonwill868]

Good work 😎👍

[@Odin851]

My 97' C1500 suburban with 276K miles stays under the first line(about 175F using torque pro) and on a 200 mile mostly highway trip doing 60mph, I got 18.5MPG. I haven't ever seen it above 180F so I'm wondering if I should replace the thermostat to get the engine temps higher?

[@NoBs48]

What does those wires go to ?

[@fernandosuarez8420]

Great videos ! Really come in handy... Have you thought on doing a leveling kit?

[@1RoadGarage]

Yes actually. I'm wanting to put a 3-4" lift...

[@isasalah5978]

I'm getting ready change Mine I'm getting smell coolant in car cabin when heater is on did something like this happened before changing yours I don't see any leaks or level coolant is full in radiator but hose going too engine is stiff were thermometer valve is !? Mine is K2500 1996!?

[@ronrobinson1990]

What year is your Surburban? I have a custom build going and your upper radiator hose looks like it will work with my application. Thanks.

[@MikhailSkulls]

8:26 That's exactly the temp my 95 stays at too.

[@Platano_macho]

My truck didn’t have one so I installed one and now the top hose is cold and the truck is overheating I did add antifreeze but not sure if I have to bleed it?

[@nihadmj]

Why you not use the double ~ valve engine cooling thermostat?

[@grendle81]

my '98 c1500 work truck and my '98 suburban never get very warm at all, replaced the thermo's with the best thermo's i could get & it still barely gets hot.

[@MikhailSkulls]

pretty common on the vortec motors.

[@grendle81]

yeah I never worried too much about it but I think it should be good to get a little heat in the engine...

[@MikhailSkulls]

I see people asking about it alot in groups i'm in but have never seen a fix posted.

[@jorgefigheroa77]

Good job man....did you for your low voltage problem? Did you get the smaller alternator pulley??

[@robertv8851]

Did you drain any antifreeze.also put a little anti seize on the bolts.

[@tylerbuilt_chevy_tough5163]

Torquing bolts people dont realize us kinda a joke if you have to use extensions those extensions makes your torque way off but yet it is unavoidable

[@AWIERD1]

I broke the exact bolt/stud on the right side of the thermostat.....

[@thegreenhouseinventor7793]

Hello-----I hate to bust your bubble but you are making many mistakes. Your cooling water looks like it is dirty and needs to be flushed out. The O-ring type gasket has a slot around the inside of it and it actually snaps over the outside of the thermostat and is in place ON the thermostat BEFORE the thermostat is lowered into position. The FLAT part of the O-ring goes on the DOWN side of the thermostat. There is a little ridge on one side of the O-ring and this goes up, facing the sky. All radiators have a drain cock located near the bottom of the radiator and you should FIRST drain out about 3 quarts to avoid any spillage when you take the housing apart. After you have finished with the installation, pour what you drained from the radiator back in before you start it up. I like that you go to Harbor Freight.

[@brucejones8847]

Nice job you need to drain out all that rusty water

[@majin_terry6658]

I think that’s my problem!

[@latrogeniwile58]

You should use a ACDELCO 12TP1D 180 degree stat (or equivalent) and a 30% mix of pure GREEN Antifreeze in distilled water, plus a bottle of Water Wetter. The Cap should be a Stant 10230 (spring vent closure). Reinstall the bolts in cleaned holes using anti-sieze. Servicing the cooling system: Remove both block plugs, and poke a screwdriver in the holes to clear the scum. I replaced mine with NPT brass plugs with a 1/8" NPT hole, and then use stainless steel hex plugs. Next time, you only need to remove the small plugs, which is much easier. Anti-sieze on all of these parts. Your best bet Water Pump is a Stewart stage 1 or stage 2. Not sure which one, as the pilot shaft and neck size have options. Serpentine belt driven pumps need CCW impeller. I think it would be # 13403 (verify).

[@GrandPrix46]

Flush that coolant and get some fresh stuff in there, was looking pretty nasty.

[@rafaelvasquez7631]

I have 95 c1500 , same tbi 350... when I removed the housing on mine it looked exactly same except it did have a housing gasket aswell... so I put one back as well as rtv... now I'm wondering if previous owner added a gasket when he shouldn't have🤔

[@JamieMac203]

Does that temp stay locked or does it fluctuate a little.

[@LookInDJProduction]

i like using Torques by user service manual ;)

[@markoftheus]

That's weird. You don't have a gasket for the thermostat housing? My 95 Yukon has that same engine, yet I have a gasket that's shaped like the thermostat housing but no round gasket on the thermostat.

[@julielordstone2653]

What size or pressure did you use

[@telekichi7]

Do not replace the coolant?

[@fandechavalones3022]

Will this fit in a 1999 tahoe

[@coleblanchard3931]

What temperature did it always sit at before you changed the thermostat? My 97 Chevy is doing the same thing.

[@1RoadGarage]

All the way down. Would barely creep up even after a long drive.

[@billwilson3665]

The link now leads to a different thermostat.

[@jamesheina3337]

Four core radiator

[@helivesonforever]

Flush that nasty ass coolant out and do not replace it with Dexcool! Flush it with distilled water for about 4 or 5 flushes, then use full strength conventional coolant. If you use 50/50 your mixture will be weak since there's still going to be a little bit of water left in the block. Add about 3/4 full strength and 1/4 distilled water. Then use a coolant tester to see if your mixture is pretty close to 50/50. If too strong, drain some antifreeze and add more distilled water. If too weak, drain and add a little bit more full strength antifreeze and retest. Looks like your old thermostat failed due to the nasty coolant. Better flush it before you're doing a radiator and heater core too.

[@Odin851]

The hoses to the heater core in my Suburban have been cut by the previous owner. I'm wondering if what you're saying is what happened to the heater core. The temp floats around 175F, so I'm thinking he may have changed the t stat from 195 to 180.

[@woopertrainer]

Would this work on a 98 Tahoe?

[@AWIERD1]

DeMarion Turner yes, but you have dexcool antifreeze. Also when taking off your bolt and its stuck don't torque it off and snap it like i did. Took half a day drilling and tapping a new threads metal shavings everywhere 😢

[@mikebennett5442]

Coolant flush first

[@jeffnorbert1871]

195 is actually not correct. Often said to be but 205 is factory spec.

[@mike-bj4dk]

yes it is 195 is stock for a tbi

[@HilltownCT]

Nice vid. Was ‘95 pre Dexcool?

[@MikhailSkulls]

in these trucks yes. They started dexcool the next year along with the vortec motors.

[@HilltownCT]

Thanks man

[@MrEyad1990]

Dee's nuts .

[@chrisjeroue7123]

Get a "power flush" done on your engine and heater core. Your antifreeze looked rust colored, not green which indicates the motor and heater core could have a lot of "sediment" in them and your heater core will soon start leaking.

[@kylehenschen0290]

It’s dexcool which is orange

[@Pluvar]

Great Job, Except For Flushing That Rusted Ass Coolant Out Of The System!!!

[@1RoadGarage]

Will be doing a flush video soon!!

[@Pluvar]

That's Great Hear... Keep Up The Good Work 1 Road
