Polyurethane Element
Inspect frequently and clean when dirty. Cleaning may be
needed as often as every 5,000 miles if the vehicle is operated
under dusty conditions.
To clean the polyurethane element, first remove It carefully
from the paper cartridge, then wash it in solvent. Wrap in a
clean dry cloth and squeeze to remove all possible solvent.
Do not wring the element or it may tear.
After cleaning, oil liberally with SAE 10W-30 engine oil and
squeeze to distribute the oil evenly through the element and
to remove excess oil. The element should be damp with oil,
not dripping. Install the polyurethane element on the paper
cartridge, taking care to have edges of the polyurethane
element over the plastic end plates of the paper cartridge.
Replace the polyurethane element if it becomes torn or other
wise damaged.
Replacement part numbers of the polyurethane element and
paper cartridge are imprinted on a decal affixed to the air
cleaner.
Fuel Filter
The in-line fuel filter at the carburetor prevents foreign par
ticles from getting into the carburetor and clogging the jets.
Ordinarily, replacement of the fuel filter is not necessary
before the recommended 15,000-mile interval. However, ab
normal operating conditions and/or dirty gasoline could cause
the element to clog sooner.
Battery Check
Your Jeep vehicle is equipped with a 12-volt battery. You
should follow these tips on battery care to assure reliable
operation and long battery life.
• Check the fluid level once a month (In hot dry weather,
check more frequently).
• Maintain the fluid level (above the plates) at the ring in the
bottom of the filler well.
• Distilled water should be used if possible. However,
drinking water, free of high mineral content, can be used.
• In freezing weather, water additions should be made Just
before driving to assure mixing with acid to prevent
freezing.
• The battery condition should be checked frequently in
cold weather. To prevent hard starting due to a low bat
tery (below 1.250 specific gravity), a battery charge will
be necessary.
