Undamaged Sending Unit Service Procedure

1. Remove the paint from the first three (3) threads of the hole in which the sender was installed. The suggested method of removing the paint is to use a wire brush or any other suitable means that will not damage the threads.

CAUTION: DO NOT USE A TAP TO REMOVE PAINT.

2. Re-install the sender. Tighten it to 8-15 lb.ft. (10-20 N-m).

3. Start the engine and check for any coolant leaks.

4. If the coolant temperature gauge doesn't operate correctly, check for other causes that could effect the gauge operation.
