Q: Where is the Thermostat Located on Dodge Challenger?
A: On 2.7L and 3.5L V6 engines, the thermostat is located on the lower left side and top front of the engine, respectively. To replace, first disconnect the negative battery terminal and drain the cooling system. Loosen the hose clamp and detach the hose(s). Remove the thermostat housing cover and discard the O-ring seal. For 3.6L V6 engines, disconnect the radiator hose and remove the thermostat housing and gasket. Clean all mating surfaces before reassembly. Install a new gasket and place the thermostat in the same direction and position. Reattach the hose(s) and tighten the hose clamp(s). Refill the cooling system and check for leaks and proper thermostat operation.
