start the engine and let it run until you can
feel the upper radiator hose getting hot. Watch
out for the engine cooling fan.
By this time, the coolant level inside the
coolant surge tank may be lower. If the level is
lower than the Maximum mark, add more of
the proper mixture to the coolant surge
tank until the level reaches the mark.
5. Then replace the pressure cap. Be sure the
pressure cap is hand-tight and fully seated.
See your dealer, if necessary.
Power Steering Fluid
When to Check Power Steering Fluid
The power steering fluid reservoir is located toward
the front of the engine compartment on the driver’s
side of the vehicle. See Engine Compartment
Overview on page 276 for reservoir location.
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.
