Tires
Weekly check the condition of the tires, and gauge the air pressure. Tires that have cuts or
cracks or little tread should be repaired or replaced.
Engine Radiator
Check the coolant level in the radiator. The coolant must cover the tubes in the top tank
(approximately 1 inch high on a clean measuring rod, stuck down filler neck).
WARNING
!
Remove cap slowly to relieve pressure from HOT radiator. Protect skin
and eyes. Hot water or steam and chemical additives can cause serious
personal injury.
The engine coolant system is normally filled with a 50/50 mixture of water and ethylene glycol.
This permanent type anti-freeze contains rust inhibitors and provides protection to -35°F (-
37°C). The use of such a mixture is recommended for both summer and winter operation.
When using water alone, be sure to add a reputable brand of rust inhibitor to prevent internal
corrosion.
It is recommended to test the freezing protection of the coolant every six months or prior to
freezing temperatures. Replenish with a fresh mixture every twelve months.
Each month, inspect the radiator exterior for obstructions, dirt and debris. If present, blow
water or compressed air containing a non-flammable solvent between the fins in a direction
opposite the normal air flow. Should the radiator be clogged internally, reverse flushing, using
a commercial product and the supplier’s recommended procedure, may correct the problem.
