How To Replace a Thermostat on 70's/80's Chevy Trucks

[@Saw_Squatch]

I was 16 or 17 when I made this video, so if you already know better than a dumb kid I encourage you to keep scrolling, if not, consider this video a lesson in doing your own research and not trusting everything you see on the internet

[@NotHomeownerApproved]

This video was perfect, showed me that my quality of labor will thrive on my k25 rebuild. I just hope I remembered to torque those leaf spring bolts after 11 shots of vodka

[@Saw_Squatch]

@@NotHomeownerApproved just keep pulling until your Pittsburgh 3/8 ratchet clicks like a torque wrench, it'll buff

[@NotHomeownerApproved]

@@Saw_Squatch I had to downgrade from Pittsburgh to kobalt after my most recent divorce (3rd). The torque “click” feature seems to come free with every tool kobalt offers

[@mikelauerman7684]

"Us mechanics"? Most (I hope) would have scraped and block sanded the surfaces clean before attempting to 'stick' the gasket's adhesive to dirty, oxidized aluminum! Clean is the doctor's friend. Leaks will result otherwise...

[@Inlinetodie]

Theres 3 types of thermostat at 3 different temperatures ratings which would you suggest for 5.7

[@Fritsvrolijk]

whats the outlet from the waterpomp asking for lpg installation thanks

[@2smokecuts]

What are the two screws on top of the housing

[@jaywilliams2857]

9/16 s

[@2smokecuts]

What are they use for though

[@NotHomeownerApproved]

Screwing

[@timothyburnsed2455]

So how much fluid should I drain out before replacing?

[@Saw_Squatch]

Timothy Burnsed you don't have to, it's not a pressurized system

[@240fxst]

My gauge is always reading just a click over cold, however I did notice a leak coming from hose from radiator leading to the thermostat. There seems to be pressure causing this since the clamps are tight on the hose. I think its stuck open maybe time to change thermostat on my 74 Cheyenne Super stepside. Thanks for sharing.

[@Saw_Squatch]

240fxst yeah thermostats and gaskets are cheap, just swap them out and maybe even replace the hose and clamps while you're at it. have fun with that truck of yours

[@robertcoyne1383]

What’s the random washer layin in the intake for? Extra parts?!

[@Saw_Squatch]

I mean it's still running all these years later so apparently I didn't need it lol

[@robertcoyne1383]

If you lose one you have an extra right there!!

[@creezygod]

hey so i'm kinda confused i have a 81 el camino and it's not on the front of engine similar to yours, it's a v6 and the closest resembling it is on the backside of the water pump, like it's built into it... please help!

[@Saw_Squatch]

+creezygod I've seen el Camino v6's before and it appeared that they were set up similarly. But if yours is different then I would start by checking wherever the radiator connects to the engine, that's usually where the thermostat is on these. Otherwise I would do a little more snooping around online to try and find either a walkthrough or a repair manual. Haynes makes a really good and comprehensive manual for all different kinds of vehicles that I recommend to everyone. Sorry I can't be of more help.

[@creezygod]

i found it, following the hose was the best tip; it's got a bunch of other things on top of it making it very hard to tell so now the adventure of figuring how to get to it begins, Thanks a lot!

[@jeremyburgess5265]

hey I've got the same truck just wondering when I shifting from 2nd to 3rd it doesn't change till about 45 to 3rd what should I be looking for to fix this problem it's a auto thanks!

[@Saw_Squatch]

Jeremy Burgess is it a hard shift or does it just feel like it's taking a long time to get to 3rd?

[@hunterpaulson2091]

On my Ford the thermostat in the housing first then the gasket

[@theflyingfetus9405]

Dont use chrome sockets on an impact youll ruin your sockets

[@anDWandy]

nice video. if you have leak problems by your thermostat. Thats because you are suppose to remove the old gasket first. razor blade and wire brush works well. i can see fluid on your intake manifold thats why.

[@Saw_Squatch]

That fluid was from the old leak before I replaced the gasket, but thanks for the tip, and that's what I actually did to get the old one off

[@cerealkill12]

Impact is not always a good idea 💡 currently off to the hardware store to buy an extractor 😂

[@NotHomeownerApproved]

I hope you’re hardware store trip went well 🥰

[@keltingr]

remember DO NOT clean the gasket surface before sticking the adhesive to the dirty oxidized surface

[@josecavada3830]

👍

[@mike-bj4dk]

DON'T WATCH THIS VIDEO he didn't clean surfaces and on older trucks definitely use rtv both sides

[@jimmysloppy]

so many things not correct... shade tree

[@nonyabiz9487]

thats a shitty ass repair job

[@jaimezapien4897]

That's all wrong buddy

[@crewcab1984rv]

Jeremy Burgess that sounds like your transmission Modulator. If you buy an aftermarket adjustable one you can adjust it by screwing it in more of screwing it out. The good thing about this modulator is as you can find to in your ships with those I recommend them just Google it and you'll find a bunch of them probly have a Turbo 400 maybe that's what I'm thinking that's what I had
