Cooling System
WARNING!
You or others can be badly burned by hot coolant or
steam from your radiator. If you see or hear steam
coming from under the hood, don’t open the hood
until the radiator has had time to cool. Never try to
open a cooling system pressure cap when the radia-
tor is hot.
Inspection
Coolant protection checks should be made every 12
months (before the onset of freezing weather, where
applicable). If coolant is dirty or rusty in appearance, the
system should be drained, flushed and refilled with fresh
coolant. Check the front of the radiator for any accumu-
lation of bugs, leaves, etc.
Check the coolant bottle tubing for condition and tight-
ness of connection at reserve tank and radiator. Inspect
the entire system for leaks.
NOTE: Check the front of the radiator for debris (leaves,
paper, etc.) regularly. A build up of such material could
lead to engine overheating.
Do not remove the cooling system pressure cap when the
cooling system is hot.
Cooling System — Drain, Flush and Refill
The cooling system should be drained, flushed and
refilled at the intervals shown on the Maintenance Sched-
ules.
If the solution is dirty and 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. Discard old antifreeze
solution according to recommended procedure.
