    Does your truck have a 6.0L or 6.6L? The 6.0 only has one thermostat. The 6.6L has two. I can help you more if I know what kind of engine you have.

If you have a duramax diesel engine it goes next to the other one. They would both be in the same housing. If you have a Gas engine it will only use 1 t-stat.
Thank You,

Make sure the thermostat was the right temp range. Had same problem on ford truck and parts store gave me a 160 when it should have been a 180 degree thermostat.

2007 Chevy Silverado 2500 HD. I was driving and my digital dashboard reported engine hot and AC turned off. My temperature gauge read cool. What do I need to replace?


This sounds like a bad coolant temp sensor that give computer false reading, check the coolant temp sensor connector and if it is good with no bad wires to connector then replace coolant temp sensor , when the computer gets a signal from temp sensor that engine is hot it turns fans on high speed to cool radiator and displays a/c turned off , if this truck does not have electric cooling fans then they wont run just explaining what happens depending on engine and cooling set up. replace coolant temp sensor and check connector.

The heater doesn't work very well on my 2000 Chevy Venture van. I'm wondering if I should try replacing the thermostat. Or, it is all computer controlled now.


If heat gauge reads normal, stays in the middle, then you do not need to mes up with the thermostat. I own a 2000 Chevy Venture and changing the thermostat was not fan.
It may be the Temperature Control Module, which you can buy for $45 and replace without problem, or may be an partially obstructed heating core. The GM Dex-Cool antifreeze, the read one, has additives, but if you do not flush the radiator every 2 or 3 years, can result in partially clogged heater core. I have done on my car twice till now, and replaced with green Prestone, on my own risk. Hope this will help. If need more information let me know. A have the Haynes manual for Chevy Venture 2000, and I am a car dealer.

You need talking with the parts guy at the GM dealer You need the "new" style thermostat housing to be able to change just the thermostat. So I ordered a new thermostat housing assembly. Here is what I got, a new aluminum two piece housing and thermostat. Hopefully tomorrow I can get this car back on the road and out of my shop.

How to replace a Thermastat on a 2003 Chevy silverado 2500 HD


The thermostat is located in the water pump on mostn never Chevy trucks. If you pull the upper fan shroud, you should see the thermostat housing. Remove the radiator hose, then the 2 bolts for the housing. Replace the thermostat, and gasket together.
