To fit Operation 12-2
1 Clean the thermostat housing. Ensure that the groove (A2) for the clip retainers and the seat for the "O" ring
are free of debris.
2 Ensure that the joint faces of the thermostat housing and the lower body are clean and that the jiggle pin
(B1) in the thermostat is free to move.
3 Renew the "O" ring and put the thermostat in position in the housing.
Caution: If the clips on the plastic collar are not fitted correctly into the groove, the collar will not be secure
and the thermostat will move out of position when the engine is in operation.
4 Press the retainer clips, and push the plastic collar into the thermostat housing until the clip retainers engage
the groove. Check that the plastic collar is a tight fit in the thermostat housing. If the collar is loose it must be
renewed.
5 Fit a new joint, the joint is fitted dry. Fit and tighten the setscrews.
6 Connect the top hose and fill the cooling system.
