REMOVAL & INSTALLATION

CAUTION
Use extreme care if removing a sender from a vehicle which has been driven recently. The coolant could be extremely hot.

The thermosensor is located to the left of the thermometer on the intake manifold.

1. Disconnect the negative battery cable.
2. Access the thermosensor on the intake manifold, and unfasten the wire harness attached.
3. Loosen the draincock at the lower portion of the radiator, and drain enough coolant into a suitable container to bring the level below the thermosensor.
4. Loosen and remove the thermosensor. Inspect the threads of the manifold, and use a thread chaser to restore the threads if damaged.
5. If reinstalling original thermosensor, remove sealing gasket and replace with a new one.
6. Installation is the reverse of removal. Pay close attention to the following:
   1. Use a new sealing gasket into hole in manifold, and hand-tighten. Using an appropriate socket, tighten the thermosensor to 2–3 ft. lbs. (3–4 Nm).
   2. Fill the cooling system with coolant and bleed.
