Water Pump

Another common malady on the 1989 - 1995 cars were the water pumps being prone to failure at about 75,000 miles. To the best of this author's knowledge, there have not been any water pump failures reported on the Generation 3 SHO's. But, being reasonable and prudent, here's the removal and installation guide . . . just in case.

Removal

1. Drain engine cooling system.

2. Remove engine appearance cover as described.

3. Remove battery and battery tray.

4. Remove drive belt from water pump and water pump drive pulley.

5. Disconnect throttle body return and supply hoses, heater core return hose and oil cooler return hose from water pump.

6. Remove two bolts retaining water hose connection to water pump housing. Pull water hose connection away from water pump and remove water thermostat from water pump housing.

7. Remove bolts and collar retaining water pump housing to LH cylinder head.

8. Disconnect water outlet hose and water inlet hose from water pump and remove water pump from engine.

9. Remove retaining bolt and belt idler pulley from water pump housing.

10. Inspect water pump for wear or damage. Replace components as required.
