Periodic Maintenance Inspection. Pontiac Sun Runner - 2WD (Canada) 1998

For 1990-2009 cars

#### Maintenance Inspections

Following are inspections and services which should be performed at least twice a year (for instance, each spring and fall).

#### Steering, Suspension and Front Drive Axle Boot and Seal Inspection

Inspect the front and rear suspension and steering system for damaged, loose or missing parts, signs of wear or lack of lubrication. Inspect the power steering lines and hoses for proper hook-up, binding, leaks, cracks, chafing, etc. Clean and then inspect the drive axle boot seals for damage, tears or leakage. Replace seals if necessary.

#### Exhaust System Inspection

Inspect the complete system. Inspect the body near the exhaust system. Look for broken, damaged, missing or out-of-position parts as well as open seams, holes, loose connections or other conditions which could cause a heat build-up in the floor pan or could let exhaust fumes into the vehicle. For exhaust system inspection diagnosis, refer to Engine.

#### Engine Cooling System Inspection

Inspect the hoses and have them replaced if they are cracked, swollen or deteriorated. Inspect all pipes, fittings and clamps. Replace these parts as needed. Clean the outside of the radiator and air conditioning condenser. To help ensure proper operation, a pressure test of the cooling system and pressure cap is recommended at least once a year.

#### Throttle System Inspection

Inspect the throttle system for interference or binding, and for damaged or missing parts. Replace parts as needed. Replace any components that have high effort or excessive wear. Do not lubricate accelerator and cruise control cables.

#### Rear Axle (All) and Front Axle (Four-Wheel Drive) Service

Check the gear lubricant level and add if needed. A fluid loss may indicate a problem. Check the system(s), and repair the system(s) if needed. Refer to Scheduled Maintenance Services to determine when to change the lubricant.

#### Brake System Inspection

Inspect the complete system.

Notice: To prevent leakage of oil filters, it is very important that you closely follow the installation instructions listed below or engine damage may result.

Inspect the brake lines and the hoses for the following:

1. Proper hookup
2. Binding
3. Leaks
4. Cracks
5. Chafing, etc.

Inspect the disc brake pads for wear and rotors for surface condition. Also inspect drum brake linings for wear and cracks. Inspect other brake parts, including the drums, wheel cylinders, calipers, the parking brake, etc.

Check parking brake adjustment.

The brakes may need to be inspected more often if driving habits or conditions result in frequent braking.

#### Clutch System Service

Check clutch pedal free travel and adjust as necessary.
