follow the upper rad hose to the thermostat housing, let the cooling system cool down drain the cooling system remove the upper rad hose remove the thermostat housing remove the thermostat and clean all gasket mating surfaces reinstall the stat with the pointed end up! install the housing and hose fill with coolant and bleed the air from the system by reving the engine to around 4500rpm this should remove the air traped in the block I hope this helpsI drive a 1999 Dodge Durango and need to change the thermostat...where is it located and how do I change it?
Follow the upper rad hose to eng, it is at the bottom of hose, you'll probably need a socket and long extension to get at it the two bolts.
Please look under your hood as in most cars its easy to find..

the above answer is the best, the only thing I would add is to remember which way the thermostat is situated in the housing.



You do not want to install it upside down.



If you have mimimal experience this is an easy replacemet to do.



Just remember which way the thermostat is oriented inthe housing!!!!!!
If you have a V8, you will have to remove the a/c compressor, because there is not enough room to remove the hose clamp holding the top hose to the thermostat housing. If you haven't done one before, it can be a daunting situation. You have to unhook the electrical connections from the compressor, remove a nut holding the hose bracket near the alternator. There is enough slack in the a/c hoses to move the compressor to the right side out of the way with out discharging the refrigerant.

The thermostat housing is steel and held on with two bolts, after removing clean all the old gasket off the manifold and housing. Place the thermostat in the manifold long side down, put on the gasket and bolt everything back like you found it. Do not overtighten and strip those bolt holes in the manifold, and tighten both sides evenly.
Its located at the dealership's repair shop.
It is not a bright idea for you to do it.

Considering you don't even know where it is located or how to do it; I'd say you don't have any experience with tools or engines.

Don't mess with it, risk of doing it wrong are high.

Consecuences are expensive.
