Hey everyone I'm new to the forums and have a question. Does anyone know where the thermostat location is for a 2001 Dodge Durango. It's a 4X4 with the 5.9L engine. I think it's on top of the block coming of the radiator hose but before I start ripping things apart I want to make sure. Any way if anyone has a picture of it they could post that would be great also. Thanks in advance.

Ok guys 11 views and no replies. I searced the forum and saw that on the 4.7L the thermostat is on the bottom of the engine. Please tell me that mine isn't on the bottom as well?

no, no, the 4.7 is in the bottom, but your 360 is where the upper hose goes into the engine...theres a water neck that sticks straight up and its under that, just like with any other engine, no quite sure what you will have to take off havent done one in a whille, but i know for sure thats where its at, just follow the upper hose into the engine and you'll find it...yeah 4.7's are backwards there's is in the lower hose

Thank you. I thought that is where it was. I traced the upper hose into the engine block and assumed that is where it was but I wanted to make sure before I started ripping stuff apart. Thank you for your help.

The thermostat is located just under the alternator on 5.9's. You'll have to remove the serpentine belt and at least tilt up the alternator, if not remove it.

Are you sure about the alternator. By the way mine looks there are two maybe 12MM bolts holding the thermostat housing to the block and I can access it without moving the belt or the alternator.

Yeah you can definitely acces the bolts, but it might be a little bit hard to pull the housing. And you want to have a little room to get your hands in, without dropping dirt and grim in there.
