How do you install 2000 Crown Victoria thermostat?

Answer 1

Remove engine cover to gain access. Remove two bolts that hold housing to manifold on the front of the engine. Coolant will leak out when the housing on the end of the top radiator hose is lifted off manifold. Wipe area clean with a rag, make sure the old o ring is not stuck on manifold. Install new o ring and thermostat making sure thermostat is facing the right way, should be marked on one side RAD which means towards radiator or the front of the car. Arched part of thermostat is up and spring side down towards the engine. Tighten two bolts evenly to secure housing to manifold carefully so as not to crack it. Fill antifreeze 50/50 antifreeze to water ratio and start engine check for leaks, tighten bolts if needed. Re-install engine cover. Check antifreeze levels when engine cools just to be sure and plastic reservoir should be half full with antifreeze.
