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

properly, the engine coolant (antifreeze) will begin to

drain from the coolant recovery bottle. DO NOT RE-

MOVE THE COOLANT PRESSURE CAP WHEN THE

COOLING SYSTEM IS HOT.

Cooling System – Drain, Flush, And Refill
If the engine coolant (antifreeze) is dirty or contains a

considerable amount of sediment, clean and flush with a

reliable cooling system cleaner. Follow with a thorough

rinsing to remove all deposits and chemicals. Properly

dispose of old engine coolant (antifreeze).
Refer to the “Maintenance Schedule” for the proper

maintenance intervals.
