GENERAL INFORMATION 0B-13
Weather-Strip Lubrication Apply a thin film silicone grease using a clean cloth. EACH TIME THE OIL IS CHANGED Brake System Inspection This inspection should be done when the wheels are removed for rotation. Inspect the lines and the hoses for proper hookup, binding, leaks, cracks, chafing, etc.
Inspect the disc brake pads for wear. Inspect the rotors for surface condition. Inspect other brake parts, theparking brake, etc., at the same time. Inspect the brakes more often if habit or conditions result in frequent braking. Steering, Suspension and Front Drive Axle Boot And Seal Inspection Inspect the front and rear suspension and the steering system for damaged, loose or missing parts, signs of wear or lack of lubrication. Inspect the power steering line and the hoses for proper hookup, binding, leaks, cracks, chafing, etc. Clean and inspect the drive axle boot and seals for damage, tears or leakage. Replace
the seals if necessary. Exhaust System Inspection Inspect the complete system (including the catalytic converter if equipped). Inspect the body near the exhaustsystem. Look for broken, damaged, missing, or out-of- position parts as well as open seams, holes, loose connections, or other conditions which could cause heat buildup in the floor pan or could let exhaust fumes seep into the trunk or passenger compartment. Throttle Linkage Inspection Inspect the throttle linkage for interference or binding, damaged, or missing parts. Lubricate all linkage joints and throttle cable joints, the intermediate throttle shaft
bearing, the return spring at throttle valve assembly, and the accelerator pedal sliding face with suitable grease. Check the throttle cable for free movements. Engine Drive Belts Inspect all belts for cracks, fraying, wear and proper tension. Adjust or replace the belts as needed. Hood Latch Operation When opening the hood, note the operation of the secondary latch. It should keep the hood from opening all the way when the primary latch is released. The hood
must close firmly. AT LEAST ANNUALLY Lap and Shoulder Belts Condition and Operation Inspect the belt system including: the webbing, the
buckles, the latch plates, the retractor, the guide loops and the anchors. Movable Head Restraint Operation On vehicles with movable head restraints, the restraints must stay in the desired position. Spare Tire and Jack Storage Be alert to rattles in the rear of the vehicle. The spare tire, all the jacking equipment, and the tools must besecurely stowed at all times. Oil the jack ratchet or the screw mechanism after each use. Key Lock Service
Lubricate the key lock cylinder. Body Lubrication Service Lubricate all the body door hinges including the hood,
the fuel door, the rear compartment hinges and the latches, the glove box and the console doors, and anyfolding seat hardware. Underbody Flushing Flushing the underbody will remove any corrosive materials used for ice and snow removal and dust control.
At least every spring clean the underbody. First, loosen the sediment packed in closed areas of the vehicle. Then
flush the underbody with plain water. Engine Cooling System Inspect the coolant and freeze protection fluid. If the fluid
is dirty or rusty, drain, flush and refill the engine cooling system with new coolant. Keep the coolant at the propermixture in order to ensure proper freeze protection, corrosion protection and engine operating temperature. Inspect the hoses. Replace the cracked, swollen, or
deteriorated hoses. Tighten the clamps. Clean the outside of the radiator and the air conditioning
condenser. Wash the filler cap and the neck. Pressure test the cooling system and the cap in order to help ensure proper operation.

Leakage Test1. Warm the engine up to normal operating temperature.
2. Disconnect the negative battery cable.
3. Remove the spark plugs.
4. Check the coolant level by opening the coolant surge tank cap and replenish if insufficient.
5. Open the engine oil filler cap.
6. Connect the tester to air pressure line and adjust the scale of tester.
7. Install the connecting hose to spark plug hole.
9. Connect the connecting hose to tester and measure the leakage volume after blowing up 5bar of compressed air. Notice Measure the leakage volume in the completely opening condition of throttle valve by pulling the acceleration cable.
10. Perform the pressure test according to the firing order.
Notice Firing Order : 1 - 5 - 3 - 6 - 2 - 4
11. Compare the leakage pressure with the specifications. 8. Position the piston of No.1 cylinder at TDC by rotating the
crankshaft.

Removal Procedure
1. Position the No.1 cylinder to TDC (OT). Notice Remove the oil filler cap at adjustment position, and check whether the intake camshaft cam ’s lobe (arrow) stays in the
upper side.
2. Cover the alternator with a clean cloth.
3. Release the tension by unscrewing the screw plug once.
NoticeIn case that the tension is reduced by unscrewing the screw
plug, reinstall after completely removing the chain tensioner.If the chain tensioner is tightened again without completely reducing its tension, then the detent spring doesn ’t return
to the original position and the tension gets excedded.

Installation Procedure
1. Connect the thrust pin (6) and the snap ring (5) to the chaintensioner housing (7). Notice When connecting the thrust pin, push in the thrust pin far enough so that it doesn ’t protrude at the chain tensioner
housing.
4. Carefully unscrew the screw plug (1), and remove the seal
(2). Notice
For the removal of screw plug, be careful that it can be
jumped out due to the force of compression spring.
Remove the screw plug only when the seal and
compression spring are damaged.
5. Carefully remove the filler pin (3), compression spring (4), snap ring (5), and the thrust pin (6).
6. Remove the chain tensioner housing (7) and the seal (8).
3. Insert the compression spring (4) with the filler pin (3) into chain tensioner housing.
2. Install the chain tensioner housing (7), thrust pin (6), snap
ring (5), and the seal (8). Installation Notice
