The water pump (3) on the world engine is attached to the water pump adapter on the front of the cylinder block.

The water pump is driven by the accessory drive belt. The water pump is connected to the water plenum by the return tube.

Turbocharger equipped engines use a smaller diameter water pump pulley then the naturally asperated engine. This allows increased coolant flow without pump cavation.

Scheme 36

The combination water/power steering pump (1) on this vehicle is attached to the lower corner of the cylinder block on the left hand side.

The water/power steering pump (1) cannot be disassembled or serviced separately.

The water/power steering pump (1) is driven by the accessory drive's serpentine belt.

Scheme 37

The water pump is turned on or off by vacuum. The Powertrain Control Module (PCM) actuates a switchover valve that turns vacuum supply to the water pump piston. A piston slides back and forth covering and uncovering a port used for coolant flow.

The controlling of the coolant flow helps manage temperature throughout the cooling system.

The water pump can be shut off if the following conditions exist

1. Engine speed is not achieved
2. The fuel injection quantity in not achieved
3. Intake air temperature is not reached
4. Coolant temperature is not reached
5. The A/C control unit does not request the heating mode
