19 - 10 STEERING

(5)Start engine and let idle.

(6)Check fluid level, add fluid as necessary.

(7)Gauge should read below 862 kPa (125 psi), if above, inspect the hoses for restrictions and repair as necessary. The initial pressure should be in the range of 345-552 kPa (50-80 psi).

CAUTION: The following test procedure involves testing maximum pump pressure output and flow control valve operation. Do not leave valve closed for more than five seconds as the pump could be damaged.

(8) Close valve fully three times and record highest pressure indicated each time. All three readings must be above specifications and within 345 kPa (50 psi) of each other.

Power steering pump maximum relief pressure is 8275 to 8975 kPa (1200 to 1300 psi.).

²Power steering pump pressures above specifications but not within 345 kPa (50 psi) of each other, replace pump.

²Pressures within 345 kPa (50 psi) of each other but below specifications, replace pump.

CAUTION: Do not force the pump to operate against the stops for more than 2 to 4 seconds at a time because, pump damage will result.

(9) Open the test valve, turn steering wheel extreme left and right positions against the stops. Record the highest indicated pressure at each position. Compare readings to specifications. If highest output pressures are not the same against either stop, the steering gear is leaking internally and must be replaced.

POWER STEERING HOSES

Service all power steering hoses with vehicle raised on hoist. Cap all open ends of hoses, power steering pump fittings and steering gear ports to prevent entry of foreign material into the components.

WARNING: POWER STEERING OIL, ENGINE PARTS AND THE EXHAUST SYSTEM MAY BE EXTREMELY HOT IF ENGINE HAS BEEN RUNNING. DO NOT START ENGINE WITH ANY LOOSE OR DISCONNECTED HOSES. DO NOT ALLOW HOSES TO TOUCH HOT EXHAUST MANIFOLD OR CATALYST.

For part reference and part location for the vehicle that is being serviced, refer to Figs. 1 to 4. These show the hose bracket locations, hose routings and fitting locations by the engine application of the vehicle. Use these figure numbers when referring to the removal or installation procedures for the power steering hoses listed below.

Ä

REMOVAL

(1)Remove bolts from power steering hose routing bracket to crossmember attachment points.

(2)Disconnect power steering hose at opening nearest power steering gear assembly. Drain the power steering fluid from power steering pump and hose through open end of hose.

(3)Disconnect opposite end of hose and remove power steering hose assembly from vehicle.
