  2. Remove radiator lower hose from thermostat housing.
  3. Remove nuts from heater tube flange studs.
  4. Loosen starter bolt at heater tube bracket.
  5. Pull heater tube out of thermostat housing and position out of the way.
  6. Remove bolt and two studs.
  7. Remove thermostat housing, O-ring and thermostat.
  8. Remove thermostat housing bolts.

3.5L Removal procedures

Where is the thermostat located


Under the hood find radiator at front of the car on either left or right side of radiator is a fat hose that will be connected to the radiator. Follow that hose to the engine and it connects to the thermostat cover that is connected to the top of the engine with two bolts holding it on. Remove both bolts, Remove thermostat cover replace with new thermostat, Scrap off old gasket on both connecting sides place in new gasket (using a gasket sealer with the gasket wouldn't hurt to) replace both bolts only SNUG tight if using sealer let sit for a hour or two. your done!!

Remove the thermostat outlet bolts and outlet

3. Remove the thermostat outlet bolts and outlet.

f389490.gif
Remove the thermostat

  1. Remove the thermostat.
  2. Clean the mating surfaces of the radiator outlet and the radiator outlet pipe.
To install:
  1. Install the thermostat.
  2. Install the thermostat outlet and bolts.
    NOTE Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  3. Install the coolant outlet attaching bolts and tighten the thermostat outlet bolts to 10 ft. lbs. (14 Nm).
  4. Install the lower radiator hose to thermostat outlet.
  5. Fill the cooling system.
  6. Inspect for leaks.

How do i change a thermostat??


buy the correct thermostat and thermostat gasket for your car, then locate the upper radiator hose. Where the upper hose connects to the engine there should be a two bolt hose connection/ thermostat housing ( could be 3 or 4 bolt, but most are 2) these bolts should be removed and then gently lift the hose and hose connection/thermostat housing exposing the old thermostat. note the position then replace the new thermostat just as the old was installed.
