"How To": GM 5.3L V8 Thermostat Replacement
Автокөліктер мен көлік құралдары
The thermostat in your engine's cooling system is what allows your coolant to pass between the engine and radiator. If it fails in the closed position, you can quickly find yourself on the side of the road with an overheated engine. A thermostat that is "stuck open" won't allow the engine to reach the proper operating temperature, which can also cause issues. In either case, it needs to be replaced. Another reason to replace it, is if you've changed a major component of the cooling system such as the radiator or water pump.
On GM's venerable 5.3L V-8, it's an easy and quick job that you can do yourself in under an hour.
While I went with one quickly available from a parts store, you can easily source a GM Genuine part from a variety of places, one being RockAuto.com

Thank you i replaced my thermostast very quick by following your step to step video. Keep up the good work.!!!
Thanks for being so specific with this topic. It’s always better to have more details than not enough. Thanks for explaining whether or not you may or may not have a petcock or whether you choose to have the whole housing or just the thermostat. The details about the gasket. It’s always nice to find a video where somebody actually explains every detail of the situation involving the topic. 99% of us get on here to learn everything we can about that specific topic and every detail counts!

I appreciate the kind words. The whole reason I started this channel was to simply help people do maintenance on their vehicles as I do it on my own. Not that I have a huge channel or following, but I also never thought it would even get to where it is right now. I'm definitely blessed by it all.
Thank you I replaced my thermostat in 20 minutes thanks to you, u rock man
Just wanted to say your channel has been a great help with my avalanche

Do you have to drain fluid? Mine doesn't have a drain plug?
I recently had to replace my old radiator and after the install I noticed the Temp meter on dash reading a lot lower than before. It used to be almost straight up near 200. After changing the thermostat it stayed below at the second tic mark which is a reading of 185F. After investigating I find that is the correct reading. So my old radiator must have been clogged up.

Could be your thermostat I thought the same thing. But theirs 2 different types of thermostat 210F or 185F.
Torque'sper manual on water pump housing bolts is eleven foot pounds. You can snap these bolts easily. And then if you can't get them out you have to replace the entire water pump. 11 ft pounds. Don't forget to fill the system and burp it, To get all the air out. Then top it off.
You don’t have to drain it but when you pull the fan shroud it ff to get the thermostat housing off whatever is in the hose and radiator above that point is going to leak out. Let it drain into a bucket or whatever and twist hose so it’s pointing straight up. Make sure housing is dry, put bolts back into housing after new thermostat is replaced, tighten bolts, put hose back on , put on shroud again and your done. U will prob loose about a 1/4 gallon if that
Didn't mention adding coolant or burping the system. Otherwise good video on replacement. NOTE: the gasket is built into the thermostat. Don't confuse it with an O ring. Prior engines used an O Ring.

Man so this through me for a loop>>>> I was replacing my t stat on 04 Tahoe 5.3 and I guess the person that installed a t stat before me made a gasket for the thermostat. It made me panic and worry that I needed to make gasket for it too. It’s never leaked from there before so I guess it didn’t hurt but I knew all the videos I watched said you don’t have to use any gasket maker or anything

No gasket maker needed. The gasket is a ring style that creates the seal.
great video. it didn't show how you replaced the t-stat. what do we do if the t-stat is stuck in the housing?
@takeroadslesstraveled6505

I actually did show it because the part I got has the housing and T-stat already together. It’s well worth the little extra money to buy them already together.

Nothing keeping the thermostat in the housing but the rubber gasket. You can't seem to get it out pull harder.
Someone please tell me why you have to drain the coolant in order ro replace the thermostat?
@takeroadslesstraveled6505
2 жыл бұрын
Because it’ll pour out of the lower radiator hose when you disconnect the hose from the t-stat housing. Draining it keeps you from making a huge mess.
Was yours running TOO COOL or too hot? I have mine now running too cool. :)

Neither actually. I replaced the radiator, and anytime you replace a major component of the cooling system you should replace the thermostat as well.
Could you please give me the OEM number if the thermostat housing. I have an older Chevy and the housing is different, I wanted to change it but couldn’t find a part number...

So the thermostat and be separated? I was under the understanding that it was one part and you had to buy a new housing as well

Indeed it can. You can buy just the thermostat and a new gasket if you want, but the kit that has the thermostat, housing, and gasket ready to be installed is just a few dollars more.

Its strange you don't have a fan or shroud to be removed for easier access to the thermostat replacement, it would have been helpful showing their removal?

Replace the housing as well or it won't seal properly and will overheat!

any reason you didn't spend the few extra dollars for an OEM thermostat? All my years on working on my car, I've learned one thing... don't trust 3rd party parts, especially alternators and starters.
