General Maintenance Information20
Explanation of Maintenance Items
Drive Belts
Inspect for cracks, excessive wearand oiliness. Check the belt tension and
adjust if necessary. Replace the belts if they are damaged.
Drive Shaft Boots
Check the drive shaft boots and clamps forcracks, deterioration and damage.
Replace any deteriorated or damaged parts and, if necessary, repack the grease.
Selected models also require periodic inspection of the drive shaft bolt for proper
torque. A qualified technician should perform these operations.
Engine Air Filter
Replace at specified intervals. When performing inspections, check for damage,
excessive wear and oiliness, and replace if necessary.
Engine Coolant
Drain and flush the cooling system and refill with an ethylene-glycol type
coolant. Inspect the radiator and condenser for leaves, dirt and insects and clean
if necessary. A qualified technician should perform these operations.
Engine Oil and Oil Filter
Replace the oil filter and drain and refill the engine oil at specified intervals.
For recommended oil grade and viscosity, refer to the
Owner’s Manual.
Engine Valve Clearance
Inspect for excessive lifter noise and engine vibration and adjust if necessary.
Aqualified technician should perform this operation.
Exhaust Pipes and Mountings
Visually inspect the exhaust pipes, muffler and hangers for cracks, deterioration
and damage. Start the engine and listen carefully for any exhaust gas leakage.
Tighten connections or replace parts as necessary.
Fuel Lines and Connections, Fuel Tank Band and
Fuel Tank Vapor Vent System Hoses
Visually inspect for corrosion, damage, cracks and loose or leaking connections.
Tighten connections or replace parts as necessary.
Fuel Tank Cap Gasket

General Maintenance Information21
Explanation of Maintenance Items
Propeller Shaft
Lubricate the propeller shaft spiders and slide yokes with lithium-base chassis grease
and the double cardan joint with molybdenum-disulfide lithium-base chassis grease,
and re-torque the bolt. Only a qualified technician should re-torque the bolt.
Radiator Core and Condenser
Inspect for debris and signs of damage. Have any problem repaired immediately
by a qualified technician.
Spark Plugs
Replace at specified intervals. Install newplugs of the same type as originally
equipped. A qualified technician should perform this operation.
Steering Gear Box
Inspect for signs of leakage. If you discover any leakage, have it repaired imme-
diately by a qualified technician.
Steering Linkage and Boots
With the vehicle stopped, check for excessive freeplay in the steering wheel.
Inspect the linkage for bending and damage and the dust boots for deterioration,
cracks and damage. Replace any damaged parts. A qualified technician should
perform these operations.
Timing Belt
Replace every 90,000 miles. A qualified technician should perform this operation.
