upper radiator hose getting hot. Watch out for the
engine cooling fans.

filler neck may be lower. If the level is lower, add
more of the proper DEX-COOL
® coolant mixture
through the filler neck until the level reaches
the base of the filler neck.
12. Then replace the pressure cap. At any time during
this procedure if coolant begins to flow out of the
filler neck, reinstall the pressure cap. Be sure
the arrow on the pressure cap lines up properly.
Power Steering Fluid
The power steering fluid
reservoir is located below
the generator and
behind the accessory drive
belt in the rear of the
engine compartment on
the passenger’s side of
the vehicle.
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.
