Removing
1. Drain the coolant (see "Coolant - replacement").
2. Remove the timing belt (see "Timing belt - replacement").
3. On a 16 valve engine remove the rear timing belt cover (see "Camshafts for 2112 and 21124 engines (16v) - removal and installation").
Note. On an 8-valve engine, use a 10 mm socket wrench to unscrew four bolts (1 and 3) and one nut (2) securing the rear belt cover.
5. If necessary, prying with a screwdriver, remove the pump from the cylinder block.
6. Remove the gasket.
Installation
We install the pump and the rear timing belt cover in reverse order, replacing the pump gasket.
