How to replace thermostat


Follow the upper radiator hose back to the engine block....it should be attached to a domed-shaped connection that attaches to the engine with two bolts,....the thermostat should be under that flanged connection....Drain coolant out of radiator...then remove the bolts...and pull the metal flange away from the engine........pay attention to the way the thermostat is positioned....usually the side with the spring goes into the engine block...pull the old one out...replace with the new one....use a new gasket or use some calking compound..or RTV to keep it from leaking..replace bolts....refill radiator.

Oil and Coolant leak of about 11/2 quarts coolant - 1/2 quart oil per night Leak 1 (Coolant) Appears to be coming from the radiator bottom right corner. Leak 2 (oil) Appears to be coming from the engine...


The passenger right side of the car doesn't have any flanges for cooling system, if that's correct then your radiator has a leak or puncture.

The driver side of vehicle has both the in and out flanges for the radiator. Very common to see leak at the drain valve leaking (not closed tightly). In the same area would be bottom flange of radiator which the composite flange is degrading and causing the leak.

The middle part of the bottom engine compartment is where your oil/coolant cooler assembly just above the oil filter. A loose oil filter could be the cause 95% of the time and 5% would be a bad o-ring from the oil cooler to the oil filter flange.

Overheating


Did you bleed the cooling system after refilling the radiator ? to bleed the system, fill the radiator with water and coolant. Run the engine until it is at a good temperature. Then turn off the engine and look for a bleeding screw at the oulet of the thermostat housing and turn it with a screwdriver counterclock wise. The trapped air will go out and coolant will start coming out. refill the radiator and repeat until only coolant comes out and no air.be careful not to burn yourself.

fill your radiator up, let the vehicle warm up and then shut the engine off. Look for the leak it could be a number of things check hoses, radiator, or the heator core inside the vehicle a strong flashlite and small adjustable mirror helps. Other items to check are waterpump, engine block freeze plugs, also check your oil if it appears milky you could have a blown head gasket.

Where is the thermostat located?


  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. 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. 0900c15280042102.jpgRemove the radiator hose from the waterneck by loosening the hose clamp . . . 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.
  6. Fill and bleed the engine cooling system with a clean 50/50 mixture of ethylene glycol antifreeze and water. 0900c15280042104.jpgLift the waterneck housing off of the lower intake manifold, then . . . 0900c15280042105.jpg. . . remove the thermostat out of its mounting flange
  7. Make sure the radiator is full and start the vehicle
