FUEL TANK INSPECTION
In addition to cleaning the fuel tank, the following
components should be inspected for wear:
Fuel Hoses
— inspect nylon and rubber hoses for signs
of wear, deterioration and hardening.
Fuel Tank Lining
— inspect the fuel tank lining for signs
of excessive amounts of oil or other foreign matter.
DRAINING ENGINE COOLANT
1. Remove the radiator pressure cap (Figure 46) only if
the coolant tempeature is below 120°F (50°C).
Figure 46. Radiator Pressure Cap Removal
2. Remove the coolant drain bolt and o-ring (Figure 47),
then allow the coolant to drain into a suitable container.
WARNING
DO NOT
remove the pressure cap from the radiator
when the engine is hot! Wait until the coolant
temperature is below 120°F (50°C) before removing
pressure cap.
Heated coolant spray or steam can cause severe
scalding and personal injury.

V-BELT
Visually examine the V-belt (Figure 48) and determine if it
is full of tiny cracks, frayed, has pieces of rubber missing,
is peeling or otherwise damaged.
Also, examine the belt and determine if it is
oil soaked
or
"
glazed
" (hard shiny appearance on the sides of the belt).
Either of these two conditions can cause the belt to run hot,
which can weaken it and increase the danger of it breaking.
If the V-belt exhibits any of the above wear conditions
replace the V-belt immediately.
