Where is the thermostat located and how do you replace it on a 1994 V6 Camry?
In almost every vehicle, the water thermostat is in a small pipe
junction leading from the radiator with an casing called a
thermostat housing. This junction may have several pipes or hoses
leading from it. The casing may have a few bolts around it, which
when removed carefully will reveal the thermostat which sits in a
small recess loosely once the casing is removed. On some vehicles,
the thermostat clips into place.
Take out and replace the thermostat and possibly replace the
gasket the housing case had between it and the base if it was
broken or worn with a small application of a gasket sealer
compound. Return the casing and tighten the bolts up to hand tight,
followed by a firm, but not overly tight quarter turn. If the
casing does not seem to fit properly, make sure the thermostat is
sitting in the recess correctly, the right way up and the casing
fits over the top completely. Don't attempt to cut away any of the
sealer compound if it has oozed out and dried, it may rupture the
gasket or create a hairline leak. Instead, gently wipe away any
excess sealer while it is still moist.
Replace any lost water in the radiator before attempting to run
the engine. After you start the car, keep an eye on the thermostat
housing for a few minutes and make sure there are no water leaks.
Also, watch the temperature of the vehicles cooling system to make
sure the thermostat was installed correctly. If overheating occurs,
there may be a problem with the thermostat. The vehicle should be
okay to drive immediately, but after a short drive, pop the hood
and give the housing another look to make sure.
