  Q: How to Install a Thermostat on a 3.7L Engine on Dodge Nitro?

  A:

  Before putting the thermostat on a 3.7L engine, first clean both surfaces where they will meet. After that, put the spring side down on the thermostat into the recessed machined groove in the housing assembly, so the rubber seal locating tab faces the notch. Put the thermostat housing on the timing chain cover and use a torque wrench to tighten the housing-to-timing chain cover bolts to 12 Nm (105 in. lbs.). After that, place the lower radiator hose onto the thermostat and splash shield and then lower the vehicle. Fill the coolant and attach the negative cable of the battery to the battery terminal. Make sure you start and run the engine for a little while, all the while checking for any leaks.

  Q: How to Service and Repair a Thermostat on a 3.7L Engine on Dodge Nitro?

  A:

  To fix or repair the thermostat on a 3.7L engine, first take away the negative cable from the battery. Remove the coolant from the system and, if it is clean, put it into a clean jar or other fitting container. Put the vehicle on a hoist and get rid of the splash shield. Next, break the seal on the clamp holding the lower radiator hose and take off that hose from the thermostat housing. Afterwards, take out the bolts that hold the housing in place and detach the housing and thermostat as well. Any time you replace the thermostat, make sure the new one is made specifically for your vehicle model and engine.
