MAINTENANCE INFORMATIONCHANGING ENGINE OIL
The air cleaner filter will become dirty during use and the filtering efficiency will be substantially reduced. Replace with a new one as needed.
1. If the engine is cold, run the engine until it reaches normal operating temperature.
2. Turn off the engine.
3. Remove the oil filler cap and drain plug. Drain the engine oil.
4. Tighten the drain plug to the specified torque.
Tightening torque
Oil pan drain plug:
35 - 45 Nm (350 - 450 kg.cm, 25 - 33 lb.ft)
5. Fill new engine oil through the oil filler cap opening.
NOTE: Do not overfill, this will cause oil aeration and loss of oil pressure.
6. Install the oil filler cap.
7. Start and run the engine.
8. Turn off the engine and then check the oil level. Add oil if necessary.
REPLACING THE ENGINE OIL FILTER
1. Use a filter wrench to remove the oil filter.
2. Before installing a new oil filter on the engine, apply clean engine oil to the surface of the rubber gasket.
3. Tighten the oil filter to the specified torque.
Tightening torque
Oil filter: 17 - 25 Nm (170 - 250 kg.cm, 10 - 18 lb.ft)
4. Start and run the engine and check for engine oil leaks.
5. After turning off the engine, check the oil level and add oil as necessary.
REPLACING THE AIR CLEANER FILTER
1. Disconnect the clip holding air cleaner filter cover.
2. Remove the air filter cover.
CAUTION: The air filter cover should be removed carefully because intake hose includes the air-flow sensor.
3. Remove the air cleaner filter.
4. Install a new air cleaner filter and replace the air cleaner filter cover.
CHECKING BELT TENSION
The belt tension is automatically adjusted by the auto-tensioner.
ADJUSTING BELT TENSION
COOLING SYSTEM
Check the cooling system for damaged hoses, loose or leaking connections,or other possible causes of coolant leaks.
ANTIFREEZE
The engine cooling system is provided with a mixture of 50% ethylene glycol anti-freeze and 50% water (For the vehicles of tropical area, the engine cooling system is provided with a mixture of 40% ethylene glycol anti-freeze and 60%water at the time of manufacture.) Since the cylinder head and water pump body are made of aluminum alloy casting,be sure to use a 30 to 60% ethylene glycol antifreeze coolant to assure corrosion protection and freezing prevention.
CAUTION: If the concentration of the antifreeze is below 30%, the anticorrosion property will be adversely affected. In addition, if the concentration is above 60%,both the antifreeze and engine cooling properties will decrease, adversely affecting the engine. For these reasons, be sure to maintain the concentration level within the specified range.
MEASURING OF ANTIFREEZE CONCENTRATION
Run the engine until the coolant is fully mixed. Drain some coolant (antifreeze),and then measure the temperature and specific gravity of the coolant. Determinates concentration and safe working temperature. If the coolant is short of antifreeze, add antifreeze to a concentration of 50%. (Tropical Areas: 40%)
REPLACING OF THE COOLANT
1. Set the temperature control lever to the hot position.
2. Remove the radiator cap.
CAUTION: Remove the cap slowly The system is pressurized and the coolant may be hot. Do not open the cap when the engine is hot.
3. Loosen the drain plug to drain the coolant.
4. Drain the coolant from the reserve tank.
5. After draining the coolant, tighten the drain plug securely.
6. Fill the radiator with the coolant up to its filler neck.
7. Fill the reserve tank with the coolant.
8. Warm up the engine until the thermostat opens, remove the radiator cap and check the coolant level.
9. When the radiator is filled up to its filler neck, install the radiator cap securely.
10. Fill the reserve tank with coolant up to the "FULL" line.
REPLACING IGNITION CABLES
The ignition cables should be replaced periodically with new ones. After replacing,make sure that the ignition cables and terminals are properly connected and positioned correctly.
NOTE: When disconnecting an ignition cable, be sure to hold the cable cap. If the cable is disconnected by pulling on the cable alone, an open circuit might result
REPLACING OXYGEN SENSOR
The oxygen sensor is a device which helps control the fuel mixture. If the oxygen sensor is damaged, the exhaust-gas cleaning efficiency as well as driveability deteriorates. Therefore, it should be replaced periodically with a new one.
FUEL SYSTEM
Tank, Lines And Connections
1. Check for damage or leakage in the fuel lines and connections.
2. Inspect the surface of fuel hoses for heat and mechanical damage. Hard and brittle rubber, cracking, tears, cuts, abrasions and excessive swelling indicate deterioration of the rubber.
3. If the fabric casing of the rubber hose is damaged by cracks and abrasions in the fuel system, the hoses should be changed.
INSPECTING STEERING LINKAGE
1. Check the steering wheel freeplay.
Maximum steering wheel freeplay: 30 mm (1.181 in.)
2. Check the steering linkage for looseness and damage.
a. Tie rod ends must not have excessive play.
b. Dust seals and boots must not be damaged.
c. Boot clamps must not be loose.
POWER STEERING FLUID LEVEL (INSPECT FLUID LEVEL)
1. Park the vehicle on a level surface, start the engine, and then turn the steering wheel several times to raise the temperature of the fluid to approximately 5O °C (122 °F).
2. With the engine idling, turn the wheel all the way to the left and right several times. Check the fluid in the oil reservoir for foaming, and its level. Replenish the fluid in the oil reservoir through the oil filter if necessary.
POWER STEERING HOSES (CHECK FOR DETERIORATION OR LEAKS)
1. Check the hose connections for fluid leaks.
2. The power steering hoses should be replaced if there is severe surface cracking,pulling, scuffing or worn steps. Deterioration of the hoses could cause pre-mature failure.
BALL JOINT AND STEERING LINKAGE SEALS, STEERING AND DRIVE SHAFT BOOTS
1. These components, which are permanently lubricated at the factory, do not require lubrication. Damaged seals and boots should be replaced to prevent leakage or contamination of the grease.
2. Inspect the dust covers and boots for proper sealing, leakage and damage. Replace them if defective.
INSPECTING BRAKE LINES
1. Check all brake lines and hoses for damage, wear, cracks, corrosion, leaks,bends and twists.
2. Check all clamps for tightness.
3. Check that the lines are clear of sharp edges, moving parts and the exhaust system.
FRONT DISC BRAKE PADS
Check for fluid contamination and wear. Always replace brake pads in complete sets.
NOTE: If a squealing or scraping noise occurs from the brake during driving, check if the pad wear indicator is contacting the disc. If it is, the brake pads should be replaced.
CAUTION: The pads for the right and left wheels should be replaced at the same time. Never split or intermix brake pad sets. All pads must be replaced as a complete set.
Thickness of pad lining [Limit]: 2.0 mm (0.079 in.)
CHECKING THE BRAKE FLUID LEVEL
1. Check the level of the brake fluid in the reserve tank of the master cylinder.
2. The level should be between the "MAX" and "MIN" mark.
3. If the level is lower than the "MIN" mark, add new brake fluid up to the "MAX"mark.
CHANGING BRAKE FLUID
1. Refer to BR-Section for air-bleeding procedures.
2. With a vehicle equipped with ABS(Anti-lock Brake System), refer to BR-section.
3. Connect a vinyl tube to the bleeder screw of each wheel cylinder. Put the other end of the vinyl tube in a vessel to receive the brake fluid.
4. Depress the brake pedal a few times. Then loosen the bleeder screw(with the brake pedal still depressed), and tighten it after the brake fluid stops flowing.
5. Repeat the above operation until there are no air bubbles in the brake fluid.
6. Repeat these steps for the other cylinders.
7. Add new brake fluid up to the "MAX" level in the reserve tank.
Brake fluid : DOT 3 or DOT 4
CHECKING TIRE INFLATION PRESSURE
Check the tire inflation pressures as follows.
TIRE INFLATION PRESSURE (CHECK WITH TIRES COOL)
Tire size 205/60 R16
Front 33 psi
Rear 30 psi
ROAD TEST
Drive the vehicle and check for abnormal conditions.
1. Check oil, fluid, fuel, water and exhaust gas leaks.
2. Check free play of clutch pedal and brake pedal.
3. Check operation of brake booster.
4. Check the operation of service brake and parking brake systems.
