How to Change the Thermostat in a Dodge Intrepid

by Contributor

Though not available since 2004, if you're tooling around in a Dodge Intrepid and you notice the heater's not working, or the engine is running too hot, chances are you need a new thermostat. Whether you're driving a first generation (1993-1997) or second generation (1999-2004) Intrepid, the procedure for changing the thermostat is basically the same.

Step 1

Raise your Dodge Intrepid with a jack and lower onto jack stands, or use wheel ramps. Disconnect the negative cable from the battery. Open the drain plug at the bottom of the radiator and drain the coolant into a suitable container. Reuse the coolant if relatively new and clean.

Step 2

Follow the upper radiator hose to the thermostat housing in all engine types except the 2.7L. In Intrepids with 2.7L engines, follow the lower radiator hose to the thermostat housing. Loosen the hose clamp at the end of the radiator hose with a screwdriver and pull the hose off the thermostat housing.

Step 3

Unbolt the two bolts holding the thermostat housing cover on and pull off the cover. In 2.7L Intrepid engines, it is easier to gain access to the thermostat housing behind the alternator by working from beneath the engine.

Step 4

Note the position of the old thermostat and remove. Install the new thermostat with the spring-side facing into the engine. Clean any old gasket residue from inside the thermostat housing cover. Install the new thermostat gasket.

Step 5

Reinstall the thermostat housing cover and tighten bolts to 105 inch/pounds. Reattach the radiator hose and tighten the hose clamp. Refill the radiator with reserve or new coolant. Reattach the negative battery cable.

Start your Dodge Intrepid and allow it to run with the heater on high until it reaches normal operating temperature. Check radiator hose for leaks and tighten the hose clamp to stop any leaks, if necessary.


  • Remove the alternator drive belt and bolts holding the alternator in place and set the alternator aside for easiest access to the thermostat in Dodge Intrepid 2.7L engines, if desired.


  • Don't drain the coolant from your Dodge Intrepid while the engine is hot.
