DESCRIPTION AND OPERATION
POWER STEERING PUMP OPERATION
On all vehicles equipped with power steering, the
hydraulic pressure for operation of the power steer-
ing gear is provided by a belt driven power steering
pump (Fig. 1). The TTA power steering pump is a
constant flow rate and displacement, vane type
pump.
In the event of a power steering pump drive belt
failure, manual steering control of the vehicle can
still be maintained. However, under these conditions,
steering effort will be significantly increased.
All vehicles equipped with power steering use a
remote mounted reservoir for the power steering
fluid. The power steering fluid remote reservoir on
the 2.0 ltr. and 2.4 ltr. engine is mounted to the rear
of the cylinder head on the passenger side of the
vehicle. The power steering fluid remote reservoir on
the 2.5 ltr. engine is mounted to the front side of the
engine between the cylinder heads.
The service procedures for the TTA power steering
pump are limited to the areas and components listed
below. No repair procedures are to be done on
internal components of the TTA power steering
pumps.

• Repair of power steering fluid leaks from areas
of the power steering pump sealed by O-rings is
allowed (See Pump Leak Diagnosis). However power
steering pump shaft seal leakage will require
replacement of the pump.
