  1. Disconnect the negative battery cable.
  2. Place a drain pan under the radiator drain and drain the cooling system to just below the thermostat level. Close the drain.
  3. Remove the upper radiator hose from the thermostat housing, then remove the housing.
  4. Remove the thermostat and discard the gasket. Where is the thermostat located? - 0900c15280042100.jpgThermostat installation detail—3.0L engine 0900c15280042101.jpgThermostat installation detail—3.3L and 3.8L engines
To install:
  1. Clean the housing mating surfaces.
  2. Dip the new gasket in clean water and place it on the water box surface.
  3. Center the thermostat on the gasket, in the water box. Remove the radiator hose from the waterneck by looseninWhere is the thermostat located? - 0900c15280042103.jpg . 0900c15280042103.jpg. . . then loosen and remove the waterneck housing retaining bolts
  4. Make certain the bolt threads are clean. Threaded bolt holes exposed to coolant are subject to corrosion and should be cleaned with a small wire brush or correct size thread-cutting tap. Install the housing, making sure the thermostat is still in the recess, and tighten the retaining bolts to 105 inch lbs. (12 Nm) for 3.0L engine or to 21 ft. lbs. (28 Nm) for 3.3L and 3.8L engines. Reconnect the upper radiator hose and tighten the hose clamp.
  5. Connect the negative battery cable.

Tempature gage to high


Yes a bad thermostat can cause and engine to get hot or overheat. That would be a good place to start. The thermostat is located in the housing where the upper radiator hose attaches to the engine. Make sure you replace the gasket also.

I was working for a company that used 1995 Caravan's for their sales force and I do not know of any sensor. I am confused by the term "cover".

Do you mean valve cover? If so does the sensor go somewhere? I can solve your problem, but I need move info. Please call or email me.

Either,way let me know the outcome. Your feed back is my only reward. Also, please rank my answer with as many thumbs as you think I should get.

My 2002 Dodge Caravan seems to be a bit sluggish, then all of a sudden the temp gauge shoots up and it's hot. We just replaced the water pump and thermostat.


check the coolant temperature sensor. the sensor is located right next to the thermostat housing. it has only two wires, disconnect plug. using a ohmeter check the resistance between the two terminals on top of the sensor when cold. resistance should be 7,000-- 13,000 ohms. check again when the engine has wormed up to about 200 degrees. the resistance should be 700--1,000 ohms. if there is not a definite change in the resistance, then remove and test in a pan of hot water. if the test is good, check the wiring harness from the sensor to the pcm.
