Chevrolet Vehicle 6500 Regular Cab 4x4

Warning: To prevent property damage, personal injury, and/or death, maintain adequate clearance between all parts of the exhaust system and all hoses, wires, and lines for engine cooling, brake system, fuel system, power steering system, and electrical system. Heat damage to hoses, wires, or lines may cause vehicle malfunction.

1. Frame: Check for cracks or bends in the frame. Make sure there are no loose, cracked, bent, broken or missing crossmembers, or crossmember fasteners.

2. Transmission: Inspect for leaks.

3. Drive Shaft: Ensure that all the shaft couplings are secure.

4. Exhaust System: Check to see that all the component parts are securely mounted and no cracks, holes, or severe dents are visible. Evidence of soot build up around the clamps or connections is a clear indicator of a leak being present. Ensure that all the hoses, wires, and air lines are secured away from exhaust components.

Check the electrical wiring for proper security, damage, and chafing.;

Clean the outside of the windshield with glass cleaner

Clean rubber blades using a lint-free cloth or paper towel soaked with windshield washer fluid or a mild detergent

Wash the windshield thoroughly when cleaning the blades

Are there any bugs, road grime, sap, and a buildup of vehicle wash/wax treatments that may cause wiper streaking?

Replace the wiper blades if they are worn or damaged

Select the conditions that caused the damage

Sign off on the windshield/wiper blades cleaning

Warning: Do not start the engine or have the engine running with the engine air cleaner/filter housing open.

Caution: Water sprayed into or on the air intake box in the engine compartment may damage the air filter or electrical components. Do not spray water into or on the air intake box.

Warning: Operating the engine with the air cleaner/filter off can cause you or others to be burned. Use caution when working on the engine. Do not start the engine or drive the vehicle with the air cleaner/filter off, as flames may be present if the engine backfires.

Caution: If the air cleaner/filter is off, dirt can easily get into the engine, which could damage it. Always have the air cleaner/filter in place when driving.

Air Restriction Gauge in the green zone

If the gauge is in the red zone, replace the air cleaner/filter and then reset the gauge by twisting the black knob until the gauge is in the green zone.

Engine air cleaner/filter housing and nearby components are free of dirt and debris

Air cleaner/filter sealing surface and the housing base are clean

Engine air cleaner/filter installed correctly

It is not necessary to regularly check rear axle fluid unless a leak is suspected or an unusual noise is heard. A fluid loss could indicate a problem. Have it inspected and repaired.

All axle assemblies are filled by volume of fluid during production. They are not filled to reach a certain level. When checking the fluid level on any axle, variations in the readings can be caused by factory fill differences between the minimum and the maximum fluid volume.

Also, if a vehicle has just been driven before checking the fluid level, it may appear lower than normal because fluid has traveled out along the axle tubes and has not drained back to the sump area. Therefore, a reading taken five minutes after the vehicle has been driven will appear to have a lower fluid level than a vehicle that has been stationary for an hour or two.

The rear axle assembly must be supported on a flat, level surface to get a true reading

To get an accurate reading, the vehicle should be on a level surface.

The fluid level should be even with the bottom of the fill plug hole, located on the rear axle. Add only enough fluid to reach the proper level.;

Warning: This procedure requires trained personnel with PPE!

Tires rotated according to the Maintenance Schedule

If unusual wear is noticed, rotate the tires as soon as possible, check for proper tire inflation pressure, and check for damaged tires or wheels.

Wheel alignment checked if unusual wear continues after rotation

Check the wheel lug nut torque after 160, 1 600, and 10 000 km (100, 1,000, and 6,000 mi) of driving.

Outer tire on a dual wheel setup rotated

Warning: If the vehicle is operated with a tire that is underinflated, the tire can overheat. An overheated tire can lose air suddenly or catch fire.

All tires, including the spare, properly inflated

Tires rotated according to the rotation pattern
