Thermostat
Engine coolant temperature
is
controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow of coolant through the radiator until the coolant
reaches
a
preset temperature.
When you replace your thermostat, a GM thermostat
is recommended.
Power Steering Fluid
When to Check Power Steering Fluid
It
is not
necessary to regularly check
power
steering
fluid unless you suspect there is a leak in the system
or you hear an unusual noise.
A
fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How To Check Power Steering Fluid
When the engine compartment is cool, wipe the cap and
the top of the reservoir clean, then unscrew the cap and
wipe the dipstick with a clean rag. Replace the cap and
completely tighten it. Then remove the cap again and
lo'ok at the fluid level on the dipstick.
When the engine compartment is hot, the level should
be at the H mark. When it's cold, the level should be at
the C mark. If
the
fluid is at
the
ADD mark, you should
add fluid.
What to Use
To determine what kind of fluid to use, see
"Recommended Fluids and Lubricants" in the Index.
Always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.
The power steering fluid reservoir is located to the right
of the
windshield washer fluid reservoir, at
the back of
the engine compartment.
