Cooling System

WARNING!

When working near the radiator cooling fan,

disconnect the fan motor lead or turn the ignition
switch to the LOCK position (OFF position for
Keyless Enter-N-Go™). The fan is temperature
controlled and can start at any time the ignition
switch is in the ON position (RUN position for
Keyless Enter-N-Go™).

You or others can be badly burned by hot engine

coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not open the hood until the radiator has had
time to cool. Never try to open a cooling system
pressure cap when the radiator is hot.

Coolant Checks
Check the engine coolant (antifreeze) protection every 12

months (before the onset of freezing weather, where

applicable).If the engine coolant (antifreeze) is dirty, the

system should be drained, flushed, and refilled with

fresh OAT coolant (conforming to MS-12106) by an

authorized dealer. Check the front of the A/C condenser

for any accumulation of bugs, leaves, etc. If dirty, clean by

gently spraying water from a garden hose vertically

down the face of the condenser.
Check the coolant recovery bottle tubing for brittle rub-

ber, cracking, tears, cuts, and tightness of the connection

at the bottle and radiator. Inspect the entire system for

leaks.
With the engine at normal operating temperature (but

not running), check the cooling system pressure cap for

proper vacuum sealing by draining a small amount of

coolant from the radiator drain cock. If the cap is sealing
