REMOVAL & INSTALLATION
- Note the radio security code and station presets.
- Disconnect the negative battery cable.
- Drain the engine coolant into a sealable container, to a level below the thermostat.
- Use a pair of pliers to release the tension from the hose clamp, then disconnect the hose from the thermostat housing.
- Remove the fasteners from the thermostat housing, remove the housing, then remove the thermostat.
- Install the thermostat using a new seal. If the thermostat has a small bleed hole, make sure the bleed hole is on the top.
- Apply an anti-seize compound to the threads of the fasteners.
- Position the thermostat housing and secure with the retaining bolts.
- Attach the hose to the housing and secure with the hose clamp
- Set the heater to the "full hot" position.
- On the 2.2L and 2.3L engines, locate the coolant bleed valve near the thermostat housing and open the valve 1 / 2 turn.
When mixing a 50/50 solution of antifreeze and water, using distilled water may help to keep the cooling system from building up mineral deposits and internal blockage.
- Top off the cooling system and overflow reservoir with a 50/50 mixture of a recommended antifreeze and water solution and bleed the system to remove any air pockets as necessary. Simultaneously squeeze the upper and lower radiator hoses to help push any captured air pockets out of the system.
- Inspect all coolant hoses and fittings to make sure they are properly installed and if previously opened, close the bleed valve.
- Connect the negative battery cable.
- Install the radiator cap loosely and start the engine. Allow the engine to run until the cooling fan has cycled two times, then turn the engine off and top off the cooling system as necessary.
- Install the radiator cap and inspect for leaks.
- Enter the radio security code.
