Check this location.
Between the alternator and A/C compressor, on the top. The other thermostat with vent holes goes toward the rear of the engine.
I believe the temp ratings are different for each.
Let engine cool before working on it.
Clean up an spilled radiator fluid. It will destroy pets liver in 24 hours if they drink it.

My 2000 chevy 3500 6.5 turbo diesel isn't throwing out heat. where are the thermostat(s) located?


The thermostat housing is located on top and front of the engine. You will see a large radiator housing coming from it. There are 4 bolts to open the housing (15mm) and hose clamp(s) to loosen on the radiator hose. Once removed just pull out the 2 thermostats. When you are replacing the thermostat(s)-the gasket(s) for the housing are on the attached to the new thermostats- As you probably noticed when pulling out the old ones.

Where is the IAT (Intake Air Temperature) sensor located on a 2002 2500HD with a 6.6 Duramax Diesel?


The intake air temperature sensor on a 6.6L diesel is part of the mass air flow sensor, located just outside the air filter housing, in the intake air snorkle going to the engine. The other one is for the turbo system and is located directly at the top of the engine in the inlet pipe for the turbo. This on is the intake temperature heater / sensor, and will set a totally different code relating to the turbo. The one you want is incorporated with the MAF sensor. Usually code P0101 sets.

Need to replace thermostat on 2005 Chevy 2500HD 4x4


The thermostat is located in the water pump next to the 2 heater hoses. I think you have to buy the housing to get a thermostat. Not serviced seperately.

Location


Right on top in the middle between the alternator and A/C compressor. The back t-stat has little vent holes that need to go towards the rear of the engine.
