Thermostat is located above the water pump in has to hoses coming out of in one for the lower end of the radiator and one on the top. there is 3 bolts around the housing and one above a 13 if im not mistaking. It is black and you need to replace the housing not just the thermostat its easy job need anymore help let me know

try looking in general area of the thermostat

It may be a couple of things, first before you replace the water pump, you need to warm the car up, and locate the thermostat houseing, it will have two hoses attached, and one will go to the radiator, and it will be on the engine, after you locate it, warm the car up, after it is warmed up, feel the hoses going too and from the thermostat houseing, if they are both warm, then it is not the thermostat, if they are not both warm, then your thermostat is junk, cheap fix, and easy to replace. let me know, and i will help you from their...........

yeah its not super hard locate wether the thermostat is at the end of the top hose or bottom hose then remove the two or three bolts holdin the housing on replace the thermostat and the gasket dont over tighten the bolts when outtin the houseing back on it will crack the houseing.coolant will leak out if u dont drain sum before u remove the thermostat housing.hope that helps if u need more info let me know

the snsr is located on the right side of trans and can be viewed from the passenger side of vehicle looking down at trans from under the hood.

this doesnt sound like a thermostat problem, rather a restricted heater core.
The thermostat housing, however, is a cheap cross-your-fingers-fix, and can be located by tracing the upper radiator hose back to the engine. The housing the hose is clamped to is where the thermostat is located. Remove 2 bolts, and replace thermostat.

heater core is under the dash on the passenger side and the thermostat is located on the engine. just follow your top radiator hose from the radiator to the engine and it stops at the thermostat
