Power Steering Fluid Troubleshooting Chart
NOTE :
Extremely cold temperatures may cause power steering fluid aeration. The air should work its way out of the system
as the fluid warms.
CONDITION POSSIBLE CAUSES CORRECTION
Low Fluid Level With Visible Leak
· Loose power steering hose fittings
or connections.
· Damaged or missing O-ring at
power steering hose tube nuts.
· Power steering line or hose failure.
· Power steering component leaking
(reservoir, pump, gear).
· Check torque on all tube nuts (at
gear and pump). Inspect clamps at
all rubber hose connections for
correct position, damage and
tension. Tighten tube nuts to
specifications as required.
Reposition or replace clamps at
hose connections. Clean joints and
reinspect for leaks.
· Remove tube nut and inspect
O-ring. If damaged or missing,
replace O-ring. Clean joints and
reinspect for leaks.
· Clean fluid from around suspect
areas. Run vehicle and inspect for
leaks. Look inside reservoir to see if
air is being ingested. Replace hoses
if necessary.
· Clean fluid from around suspect
areas. Run vehicle and inspect for
leaks. Look inside reservoir to see if
air is being ingested. Replace power
steering component if necessary.
Aerated Fluid
· Low power steering fluid level.
· Air leak at power steering supply
hose, reservoir or pump.
· Check fluid level and fill to proper
level if necessary. Check for leaks.
Make sure all air is bled from
system.
· Inspect components. Place a hand
vacuum pump with reservoir and
verify that system can sustain
vacuum. System should not lose
more than 1 psi in 2 minutes (make
sure vacuum pump is sealed well to
the reservoir). Replace steering
component if necessary.
