Prizm L4-108 1.8L DOHC VIN 8 MFI (1998)
Power Steering Pump: Description and Operation
The power steering pump uses a ten vane hydraulic pump to provide steering assistance. The pump is driven by the engine using a multi-ribbed belt and
uses an engine speed sensing type flow control valve. This valve reduces the output pressure to the gear as engine speed increases, providing higher
pump pressure when the engine is at or near idle speed and a lower (but safe) pressure at high engine speed.
This vehicle uses a power steering pump which is mounted at the front of the transverse mounted engine toward the rear of the engine compartment. This
pump has a separate cower steering fluid reservoir.
