• Q: How to Maintain Your Thermostat for Optimal Performance on 2002 Chrysler 300M?

  A: When servicing the engine coolant thermostat, make certain the engine coolant is not at a hot or high pressure level. To start, pull out the negative cable from the remote jumper terminal and drain your car's coolant. Put the vehicle on a hoist and afterward remove the electrical connectors from the engine oil and power steering pressure switches. Now, separate the radiator and heater hoses from the thermostat and then remove the bolts around the thermostat housing. Get rid of the housing, thermostat and gasket. To install, make the surfaces of the gasket sealing areas clean and then add the thermostat and the gasket into the thermostat housing, securing it with bolts. Join the thermostat and housing to the cylinder block and tighten each screw to 12 Nm (105 in. lbs.). Fix the heater and radiator hoses together, add the hose clamps and reattach the connectors of the engine oil and power steering pressure switches to the electrical system. Drop the vehicle, attach the negative battery cable to the remote jump starting point, add engine coolant and then place the negative terminal back onto the remote jump start terminal.
