How do you change the thermostat in a 1999 Dodge Durango?

Answer 1

These are instructions for a V8 Durango. You first remove the thermostat housing. Follow the upper radiator hose to where it heads into the engine vertically. This job is much easier if you remove the alternator and the upper alternator support bracket first. Squeeze the spring clamp on the radiator hose and pull the hose off. If you can't remove it, you may have to cut the rubber and shorten or replace the hose later. The metal part the hose connected to is the housing. Remove the two bolts and pull it out. The thermostat will either be stuck inside here or still resting on top of the engine. Pay attention to which way it is facing when you remove it because it must be reinstalled facing the proper direction. Replace everything in the same order it was removed.
