  Q: How to Install a Thermostat for a 3.7L/4.7L Engine on Jeep Commander?

  A:

  Always make sure to clean the areas that the timing chain cover and thermostat mold together before installing the engine coolant thermostat. Now, set the thermostat spring-side down into the groove on the chain cover. After that, lay the thermostat housing in place. Connect both sides of the housing to the timing chain cover with two bolts and tighten them to 115 in. lbs. of torque, making sure that nothing is looser than the other and that the thermostat stays centered in its groove for the housing to prevent any trouble and leaks. After that, join the lower radiator hose to the thermostat housing, add the splash shield and lower the car. Pour the coolant into the cooling system, reattach the negative Battery Cable and start the engine to warm it up while you watch for leaks.

  Q: How to Service and Repair a Thermostat for the 3.7L/4.7L Engine on Jeep Commander?

  A:

  The first step in cleaning the 3.7L/4.7L engine's thermostat is cleaning the areas where the timing chain cover and thermostat housing fit. After that, set the thermostat's spring part into the recessed groove and place the thermostat housing properly over the cover. Bolts to secure the housing must be placed at the designated spots and tightened to 13 Nm (115 in. lbs.) torque, so there is even pressure and the thermostat stays in the middle of the groove to save the timing chain cover, prevent housing cracking and avoid leaks of coolant. Then, link the lower radiator hose to the thermostat housing, position the splash shield and lower the car. Fill up the cooling system, link the positive battery cable to the battery again, start the engine and let it heat up while searching for leaks.
