Diesel trucks are common because they can last forever as long as you take care of them properly. The Duramax Diesel maintenance schedule is actually two schedules. One is for driving under normal conditions, and the other is for driving under severe conditions. At Mevert Automotive & Tire Center, we have more than one mechanic trained in maintaining and repairing Duramax Diesel trucks to keep the Duramax running for years to come.

So, what is the difference between ordinary and severe driving? Severe driving is when you constantly:

• Tow heavy loads;
• Driving in heavy traffic;
• Do most of your driving on gravel roads;
• Idle excessively; or
• Do a lot of mountain travel.

Additional Maintenance Items

The tires, brakes, fluids, belts, and hoses are just as essential as maintaining the engine and transmission. If you do a lot of driving, you should check the fluids every two weeks and top them off as needed. Bring your Duramax diesel into the shop to locate and repair the leak if you are losing fluids.

When our diesel mechanic does other maintenance, he will also check the belts, hoses, brakes, and tires. These items are wear and tear things that will wear out quicker the more miles you put on the truck. Also, driving on gravel roads wears tires out fast. Frequent driving on hills and mountain roads takes a toll on a truck’s brakes. Check these fast-wearing items more frequently – at least once per month.

When you need a maintenance tech you can count on, bring the Duramax Diesel to Mevert Automotive & Tire Center for all your maintenance needs.
