Drain the water from your 1997 Chevy Monte Carlo cooling system. Remove the water supply hose. Remove the thermostat housing retaining bolts. The thermostat will lift out. Reverse the process to install the new thermostat.

Answer: The thermostat is in an alluminum housing. From under the hood, follow the upper radiator hose from the dr. side of the radiator to the engine. 2 bolts hold the housing on. Under you will find the thermostat.- TechJK-------------------------------- Just follow the main hose from the radiater,and where it ends that's where it is.


In a removable housing at the engine end of the upper radiator hose


Should be in a removable housing at the engine end of the upper radiator hose


mounted on the side under the throttle body. Just follow the upper radiator hose (on driver side) to the thermostat housing. Kinda hard to get to, so make sure you remove as much as possible to get to it

just follow the top radiator hose to the engine and where it clamps on you will find the thermostat, 2 bolts takes the housing off and the thermostat is under it.



As you are facing the engine looking under the hood, it is on the right side, under the throttle body, inside the thermostat housing. It (the thermostat housing) is a cast metal tube with a thick rubber hose running to it.


It is normally where the upper radiator hose meets the engine block.
