Mercury Mountaineer Replacement Thermostat Housing Information


In order for the temperature of your Mercury Mountaineer to be registered properly, the thermostat of your vehicle needs to be properly covered and protected. The thermostat housing is a metal or plastic component that provides this needed shelter and sits over the thermostat in your vehicle. You can find the thermostat housing bolted securely to your engine. The thermostat housing aids your thermostat in regulating the engine temperature by limiting the flow of coolant from the radiator to the engine. However, a cracked thermostat housing can introduce contaminants to the thermostat, which can cause the thermostat to malfunction. To keep your thermostat and engine in good shape, replace a cracked or worn out thermostat housing immediately.

When selecting a new thermostat housing, make sure your replacement fits the make, model and year of your vehicle. At Parts Geek, you will find replacement thermostat housing units made to the specifications of your Mercury Mountaineer.


They are available for the following Mercury Mountaineer years: 2010, 2009, 2008, 2007, 2006, 2005, 2004, 2003, 2002, 2001, 2000, 1999, 1998, 1997, 10, 09, 08, 07, 06, 05, 04, 03, 02, 01, 00, 99, 98, 97.

Somewhat Satisfied
Reviewer: Mountaineer

Product was exactly what I needed and at an excellent price. Product took 8 days to arrive, which was its only flaw. However well worth the savings vs. what my mechanic quoted me.
