Because of their efficiency and durability, diesel engines have become the standard in work trucks, recreation trucks, and power fleets. Many of our drivers simply drive them off-road or take them to the lake to pull their boats or a trailer with their ATV or RTV or a multitude of other things. Our fleet customers use them for their business needs as they hold their value and do the heavy lifting other trucks don't.

Our diesel service technicians here at Kelley's Auto & Diesel Repair in Crestview, FL are seriously qualified and trained to work on your diesel Ford, GMC, Dodge, or Chevy truck engine and are up to date on all the training with the diagnostic equipment needed to service that Cummins, Power Stroke, or Duramax diesel engine whether it be a standard diesel service or maintenance job or a complete and in-depth diesel repair job such as an engine or transmission repair or replacement. Our diesel mechanics are the best in the business and can get your truck in the bay and out and let you know what is wrong with it as well as give you options for service and a plan of action at a cost that is less than what you will find at the dealership. Our diagnostic equipment you will find is as good as if not better in some cases than the dealership and our diesel mechanics see more diesel engines than their service technicians do. Also, we can do factory warranty work and factory service work right here in the shop saving you time and money!

Our diesel mechanics handle many kinds of repairs on the Ford, Chevy, Dodge, & GMC trucks that come into the shop such as electrical systems, major engine repairs, or retrofit engines with emission control systems to comply with pollution regulations. Diesel engine maintenance is becoming increasingly complex as engines and other components use more electronic systems to control their operation.

Diesel Maintenance, Key to Fewer Repairs

Your light-duty diesel engine is very different from a gas engine starting with the way it gains power using compression in the combustion chamber to ignite the fuel versus a spark like a gas engine. The real key to keeping that diesel engine in top shape is filters and with regularly scheduled maintenance and fluids - specifically diesel engine oil, exhaust treatment fluid, power steering fluid, coolant, brake fluid, automatic transmission fluid, rear differential fluid. On 4×4’s, you also have transfer case fluid and front differential fluid. It is more than you need on a gas engine but the durability and power you get with diesel are worth it and the routine maintenance will save you thousands of dollars in repairs easily.  Here at Kelley's Auto & Diesel Repair our diesel techs also realize that light-duty trucks are not all alike, thus keeping them at peak performance requires flexibility.

Some of our drivers are typical and can stay within the standard "suggested" maintenance and others are a bit harder on their vehicles based on the jobs they use them for or the way they "play" in them maybe while off-roading using the 4x4 features.  Either way, we can schedule their maintenance around those needs and make sure repairs are done when it is convenient and avoided where possible!  Here at Kelley's Auto & Diesel Repair, we call that reliable service!
