Thermostat Valve Replacement

Model: Chrysler Pt Cruiser MK 1 - Years 2000-2010
Part: Thermostat

The thermostat valve activates when the coolant temperature in the engine exceeds 90°C and opens to exchange this liquid with the cooled liquid in the radiator from the fan. It is clear that a malfunction of this valve could cause the engine to overheat, with obvious consequences. The valve is located just under the plastic tube where the radiator filler cap is applied. To remove it, it is necessary to allow the engine to cool, drain the liquid from the drain plug under the radiator, and remove the intake manifold. At this point, you can unscrew the two pins at the base of the tube and extract the thermostat valve.
