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.

1B1-50 M162 ENGINE MECHANICALInstallation Notice
Make sure the crankshaft bearing cap properly seated in place in the crankcase side. When perfectly installed,the projected part (arrow) locates in the left side (intakemanifold side).
Assemble so that the projected part of the cap andcrankcase face the same direction.
Removal & Installation Procedure
1. Unscrew the connecting rod bearing cap bolt and remove
the bearing cap. Installation Notice
2. Unscrew the crankshaft bearing cap bolts and separate the upper and lower bearing shells and thrust washers. Installation Notice
Remove the bearing cap from front (pulley side) to rear.
Make sure that the upper and lower bearing shells do not change each other and coat with engine oil.
The oil grooves (arrows) in the thrust washers must faceoutward and insert the thrust bearing into the bearingcap.
There are five kinds of thrust washers by thickness. Selectthe proper washer when repaired.
3. Remove the crankshaft.
4. Installation should follow the removal procedure in the reverse order.
5. After completion of the installation, check for the rotating condition of the crankshaft.
Make sure that the upper and lower bearing shells do
not change each other.
Coat the bearing shell with engine oil.
Install the bearing cap according to the consecutive
number.

Inspection
1. Position the No.1 cylinder piston to TDC (OT) by turning the crankshaft. Notice When the OT mark on vibration damper is aligned with timing
gear case cover, the intake and exhaust cam of cylinderwill make the slope to the center and will face up. In this
way, the adjustment hole of the intake and exhaust camshaft will match in line with the cylinder head upper end, at 3
o’clock, and 9 o ’clock direction each other.
2. Check the timing as below procedure; - Check if the camshaft adjustment hole is positioned to 3 o’clock direction at the intake side and to 9 o ’clock
direction at the exhaust side, respectively and align withthe cylinder head mating surface.
- At this condition, check if the OT mark on vibration damper aligns with the marker on the timing gear case.
