
for an oil leak, clogged oil filter, or defective oil pump.
NOTE: If oil pressure is higher than specified, check

for too heavy engine oil weight (see General Informa-
tion/Foreword), clogged oil passage, or improper
installation or type of oil filter.

Fuel Pump

NOTE: The fuel pump is not a serviceable compo-

nent and must be replaced as an assembly (see FUEL

tem section).

Fuel/Vent Hoses

Inspect the fuel lines per the maintenance schedule.
Damage from aging may not always be visible. Do not
bend or obstruct the routing of the vent hose or fuel
return hose.

Liquid Cooling System

NOTE: Use a good quality, biodegradable gly-

col-based, automotive-type antifreeze. When filling
the cooling system, use the recommended cool-
ant/water mixture or one which will satisfy the coldest
anticipated weather conditions of the area in accor-
dance with the coolant manufacturer's recommenda-
tions.
! WARNING
Never check the coolant level when the engine is hot or
the cooling system is under pressure.
CAUTION
After operating the vehicle for the initial 5-10 minutes,
stop the engine, allow the engine to cool down, and
check the coolant level. Add coolant as necessary.
