REMOVAL & INSTALLATION - 3.0L OHV Engine

CAUTION Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.

1. Drain the coolant until the level of the coolant is below the level of the thermostat.
2. Disconnect the upper radiator hose from the water hose connection.
3. Unfasten the three water inlet connection retaining bolts and remove the water hose connection.
4. Remove the gasket and thermostat from the water hose connection. Discard the gasket.
   

1. Clean the water inlet connection mating surfaces.

1. Place the thermostat in the water hose connection making sure the thermostat jiggle valve is facing up.
2. Install the new gasket and place the water hose connection assembly into position.
3. Install the water hose connection assembly retainers and tighten them to 89-124 inch lbs. (10-14 Nm).
4. Connect the upper radiator hose to the water hose connection.
5. Fill the engine with coolant, start the engine and check for leaks.
6. Stop the engine and top off the coolant recovery reservoir as necessary.

it's possibly stuck in the water pump, if not, it might have been removed. sometimes people take them out so the car will not overheat, the down side to that is your air will not work

Hi,
The thermostat is located in a housing on your engine that the top radiator hose connects to... but it isn't tied to your heater problem. The thermostat restricts coolant flow until the engine warms up, but doesn't control the car heater.
You may have a fuse issue if the fan isn't blowing any air. That's an easy check and fix. Autozone might check it for you.
I hope this helps... Good luck.
