  Q: How to Maintain a Thermostat on Dodge Durango?

  A:

  When servicing the thermostat, confirm the radiator draincock isn't open during hot and pressurized operation to keep from being seriously burned by the coolant. If the old coolant is clean, save it in a clean container for possible use later and check that the new thermostat fits your car's model and engine. Take the negative cable out on the battery, drain the cooling system and put the vehicle onto a hoist. After removing the splash shield, unclamp the lower radiator hose near the Thermostat Housing and take off the hose. Then, get the thermostat housing bolts out, the thermostat housing and the thermostat too. Wipe the mating surfaces of the timing chain cover and thermostat housing, then put the spring side of the thermostat into the indented groove on the timing chain housing. Position the thermostat housing on the timing chain cover and then tighten the two housing-to-timing chain cover bolts to 13 Nm (112 in. lbs.) torque to make sure the housing is tight and centered so as to not crack, damage the timing chain cover's threads or allow coolant leaks. Install the lower radiator hose onto the thermostat housing, affix the splash shield again, set the vehicle on its proper level, add coolant to the system and reattach the negative side of the battery cable to its terminal. After that, run and warm up the engine while watching for any leaks.

  Q: How to Replace a Thermostat in Your Engine Coolant System on Dodge Durango?

  A:

  The replacement engine coolant thermostat needs to match the make and model of your vehicle's engine. First, take the negative cable from the battery and empty the cooling system. Get the car up on a hoist and take off the splash shield. After that, remove the clamp and the lower radiator hose from the Thermostat Housing. Remove the mounting bolts for the thermostat housing, the thermostat housing and then the thermostat. Wipe down all around the mating surfaces of the timing chain cover and thermostat housing, followed by installation of the thermostat with its spring side placed in the recessed machined part of the timing chain cover. After positioning the thermostat housing on the timing chain cover, bolt the part to the cover, tightening all bolts to 13 Nm (112 in. lbs.) to hold it evenly and prevent cracks in the thermostat, possible damage to the timing chain guide and leaks of coolant. Attach the bottom radiator hose to the thermostat housing, fit back the splash shield, lower your car, add coolant to the system and reattach the negative battery cable. After that, power on the engine and inspect for any leaks.
