1. Radiator
Inspect radiator fins. They must be clean, free
of mud, dirt, leaves and any other deposit that
would prevent the radiator to cool properly.
Remove as much deposits as you can with
your hands. If water is available in proximity,
try rinsing the radiator fins.
If available, use a garden hose to rinse the
radiator fins.
WARNING
Never clean radiator with your hands
when it is hot. Let the radiator cool down
before cleaning.
CAUTION: Be careful not to damage the ra-
diator fins when cleaning. Do not use any ob-
ject/tool that could damage the fins. The fins
are purposely thin parts to allow efficient cool-
ing. WHEN HOSING, USE LOW PRESSURE
ONLY. NEVER USE A HIGH PRESSURE
WASHER.
