2002 Dodge Grand Caravan Install Thermostat
If the thermostat in the 2002 Dodge Grand Caravan malfunctions, the engine may not warm up properly and you may not be able to heat the cabin of the vehicle. This is annoying for the driver and passengers, especially if the thermostat fails in the winter. If the thermostat fails, replace the thermostat as quickly as possible to prevent extended use of the vehicle without proper engine heating.
 Tools Used
 Install Thermostat
- Drain two gallons of radiator fluid from the radiator via the petcock on the bottom of the radiator. You can reuse the fluid later so use a clean container.
- Locate the thermostat by following the upper radiator hose from the radiator to the housing on the engine.
- Pry the clamp off the hose with a pair of pliers. Pull the hose off the housing.
- Remove the bolts that secure the housing to the Caravan's engine with a socket and ratchet. Pull the housing off the engine.
- Pull the thermostat out of the engine. Remove and discard the thermostat gasket.
- Clean the surface of the thermostat housing and the engine with a clean towel.
- Install the new gasket. Put the new thermostat into the hole.
- Place the thermostat housing on top of the gasket. Thread the bolts into the housing with your fingers. Tighten the bolts with the socket and ratchet.
- Slide the hose onto the housing. Secure the hose with the clamp.
- Pour the radiator fluid back into the radiator.
