The power steering fluid level should be between
the MIN COLD mark and the middle mark just
above it. See
Fig. 25.5 . If needed, fill the reser-

Check the engine coolant level in the radiator
surge tank. See
Fig. 25.6 .
NOTICE
Coolant must be filled to the COLD MAX line of
the surge tank. Low coolant could result in en-

age.
5.1 If the coolant is low, fill the surge tank to
the MAX line with a 50/50 mixture of water
and the type of antifreeze currently in-
stalled in your vehicle.
5.2 If the surge tank was empty, start the en-
gine after refilling and check the level
again when the engine is at operating
temperature.
