My heat stop working,i was told it is the termostat can not find the termostat

Inside of the large heater hose. you will see something that looks like a towball attachment on the top, side of you block. It has two bolts.

The t-stat is located on the front side of the engine underneath. you actually have better visibilty underneath the vehicle. i would perform a flush prior to replacing any parts. if it was the t-stat, you would also have over heat issues. a t-stat is nothing more then a temperature sensitive, mechanical restriction in the cooling system. wax pellets heat up during the warm up process allowing the engine to heat more rapidly during cold start and push the valve open allowing for flow to the radiator. go to your local parts store and for about $10 you can get a flush chemical which will help flush your system of contaminants and corrosion and then refill the system with fresh coolant and distilled water. be sure that the system is totally full and bled or you will know the first time you take it out and it over heat due to lack of fluid.
