Temperature gauge sender removal and refitting

Removal
1 On SOHC models, the temperature gauge sender is located on the front left-hand side of the cylinder head, just in front of the inlet manifold. On CVH models, the sender is located on the front face of the inlet manifold, next to the thermostat housing. On DOHC models, the sender is located at the front of the inlet manifold (see illustration).

2 With the engine cold, slowly unscrew the expansion tank cap to release any remaining pressure from the cooling system, then refit the cap.

3 Disconnect the wiring from the sender terminal (see illustrations).

4 Unscrew and remove the sender, and temporarily plug the aperture.

Refitting
5 Refitting is a reversal of removal, but smear a little sealing compound on the sender unit threads before fitting.

6 On completion, check and if necessary topup the coolant level.
