the engine compartment on the passenger’s side,
near the diagonal cross brace. See “Engine

information on location.
NOTICE:
Your radiator cap is a 15 psi (105 kPa)

type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating. Be sure the arrows on the cap
line up with the overflow tube on the radiator
filler neck.

rear of the engine compartment, on the passenger’s side.

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.
