How do you replace a thermostat on a 1995 Crown Victoria?

Answer 1

The thermostat is between a housing and the top of the engine, at the end of the upper radiator hose. There are two bolts on either side of the housing that need to be removed. The air intake (The black plastic cover, from the air filter to intake.) is in the way. There is one small bolt that needs to be removed (on the back/ passenger side) this should give you enough wiggle room to get at the housing bolt. Once the two bolts are removed, lift the housing out of the way and you will see the thermostat. Remove it and the gasket. Clean the surfaces if they require it, and place the new thermostat in. (the spring side goes into the engine) Replace the two bolts, and the air intake housing and you're done.

(if you start the car and it won't idle, some vacuum hoses have become attached. re-attach and it will idle fine.)
