Diesel Truck Maintenance Checklist

Diesel fleet managers should follow a preventive maintenance checklist prior to their drivers hitting the road for each trip. This involves checking the important elements of the truck, including lights, tires, turn signals, hazard lights and much more. Those completing the inspection should watch out for unusual sounds and basic warning signs that indicate the need for repair, such as fuel contamination, oil oxidation or a black exhaust problem. Truck Trailer Mobile Inc. can provide comeplete PM services as well as administrative fleet assistance.
