HYDRAULIC PRESSURE IN P/S CIRCUIT
CHECK
1) After cleaning joint of high pressure hose and P/S pump thor-
oughly, disconnect hose from pump and install special tool (oil
pressure gauge, attachment and hose).
Tighten each flare nut to specified torque.
CAUTION:
Take care not to cause damage to A/C condenser during
service operation, if equipped.
Special Tool
(A): 09915-77410 (Oil pressure gauge)
(B): 09915-77420
2) Check each connection for fluid leakage and bleed air.
(Refer to AIR BLEEDING PROCEDURE.)
3) With engine idling, turn steering wheel and warm up engine till
temperature of fluid in P/S fluid reservoir rises to 50 – 60_C (122
– 140_F).
4) Check line pressure by measuring hydraulic pressure with en-
gine idling and hands off steering wheel.
Line pressure: Lower than 1000 kPa (10 kg/cm
2
, 142 psi)
When line pressure is higher than specified values, check con-
trol valve and piping for clogging.
