Power Steering General Servicing Chevrolet Camaro III рестайлинг

TROUBLE SHOOTING

Refer to TROUBLE SHOOTING - BASIC PROCEDURES article in the GENERAL TROUBLE SHOOTING section.

Serpentine Belt

1. On vehicles with serpentine belts, belt tension is adjusted automatically. Adjustment is not necessary. The belt tensioner moveable portion has indicator marks that align with marks on the non-moveable portion of tensioner.
2. When mark on moveable portion aligns with the "REPLACE BELT" mark, belt needs replacing. To install new belt, route new belt in same manner as old belt.
3. Turn tensioner as far towards "MIN. BELT" mark as possible. When new belt is around tensioner, release tensioner. Ensure mark on moveable portion of tensioner is between "MIN. BELT" mark and "NOM. BELT" mark. (Scheme 1)

Except Serpentine Belt

1. Using a belt strand tension gauge, check tension of power steering belt. Refer to «POWER STEERING BELT TENSION SPECIFICATIONS»(/chevrolet/camaro/iii-1985-1992/remont/manual-power-steering/#power-steering-general-servicing) table.
2. To adjust belt tension, loosen power steering pump mounting bolts and adjusting bolt. Carefully pry pump until belt is to specification. See «POWER STEERING BELT TENSION SPECIFICATIONS»(/chevrolet/camaro/iii-1985-1992/remont/manual-power-steering/#power-steering-general-servicing) table. Tighten bolts.

TESTING

Note. Before testing power steering system, check fluid level, belt tension, pump pulley, tire pressure and engine idle speed.

PRESSURE TESTING

1. Remove high pressure line from pump. Attach Adapter Fitting (J-5176-11) to pump. (Scheme 2)
2. Using Pressure Gauge (J-5176-02) and Adapter (J-5176-12), connect gauge to hose.
3. Open valve fully. Run engine until fluid reaches normal operating temperature. Check fluid level. Add if necessary. With engine at operating temperature, pressure reading should be 80-125 psi (5.6-8.8 kg/cm 2 ).
4. If pressure is more than 200 psi (14 kg/cm 2 ), inspect system for restrictions or faulty poppet valve. Alternately close and then open gauge valve fully 3 times while recording highest pressure obtained. CAUTION: DO NOT hold valve closed for more than 5 seconds as pump damage may result.
5. If recorded pressures are all within 50 psi (3.5 kg/cm 2 ), pump performance is acceptable. If pressures are high and not within 50 psi (3.5 kg/cm 2 )) of each other, flow control valve is sticking.
6. If pressures are constant and more than 100 psi (7.0 kg/cm 2 ), but less than 1350 psi (94.9 kg/cm 2 ), replace flow control valve. Retest pump pressure.
7. If pump meets specification, leave valve open. Turn steering wheel from stop to stop. Record and compare highest pressure with maximum pump pressure.
8. If pressure at both stops is not similar to maximum pressure, steering gear is leaking internally. Shut off engine, remove testing equipment, check fluid level, or make necessary repairs.

Note. Alternative method of testing system pressure and measuring rate flow can be performed using Power Steering Analyzer (J-25323), using instructions with analyzer.

SERVICE INTERVALS

Check fluid level every 7500 miles. If vehicle is driven less than 12,000 miles a year, check fluid every 3000 miles.

CHECKING FLUID LEVEL

Clean filler cap and neck. Check fluid level with engine off and fluid at normal operating temperature. Fluid level must be between "FULL" and "ADD" marks on dipstick.

BLEEDING & REFILLING SYSTEM

1. Fill pump reservoir. See «RECOMMENDED FLUID TYPE»(/chevrolet/camaro/iii-1985-1992/remont/manual-power-steering/#power-steering-general-servicing) table. Operate engine until power steering fluid reaches operating temperature. Stop engine. Recheck fluid level. Add fluid as necessary. Repeat procedure until fluid level stabilizes.
2. Raise and support vehicle so front wheels are off ground. Start engine. Turn steering wheel from side-to-side several times. Avoid hitting stops or holding wheel in full left or right position. Fluid level should remain visible.
3. Return wheels to center position. Operate engine for 2-3 minutes. Road test vehicle. Recheck fluid level. Fluid containing air will have a milky appearance. All air should be eliminated to obtain normal steering.
