2. On some vehicles, access is easier if the front-end beauty panel and the air cleaner are removed.
3. Remove the 2 bolts securing the thermostat housing to the intake manifold.
4. Remove the thermostat housing.
5. Remove the thermostat and O-ring from the housing.

1. Install the thermostat and new O-ring to the housing.
2. Install the thermostat housing to the intake manifold. Tighten the thermostat housing bolts to 18 ft. lbs. (25 Nm).
3. Refill the cooling system using a 50/50 mixture of water and ethylene glycol antifreeze.
4. Install the air cleaner and beauty panel, if removed.
5. Start the engine and check for coolant leaks. Allow the engine to come to normal operating temperature. Recheck for coolant leaks.

The service engine soon light indicates you have a problem with the engine management system.The only way to get it to stay off is to lacate and repair whatever is not working correctly. Requires very specialized equipment. Take it to your mechanic.

Get a new cylinder put old key with chip in it. Find orange wire from old lock cylinder at bottom of steering column just under dash. Disconnect and connect new wire from new lock cyl. Get a copy of the old key for the old lock cylinder {no chip needed} to start car. Hide or mount new lock cylinder hidden under dash. Remove chip key to activate theft system.
