Keep Your Diesel Running Through Every Season

Book Seasonal Diesel Prep & Maintenance in Abilene

Temperature extremes in West Texas place heavy demands on your diesel pickup's fuel system, battery, and cooling components. Cold mornings can cause hard starts if glow plugs or fuel heaters fail, while summer heat stresses cooling systems and accelerates battery degradation. JR Diesel Performance provides seasonal diesel prep and maintenance services that address cold-start reliability, fuel system protection, and cooling performance to keep your truck ready for work, towing, or long highway drives throughout Abilene.

Your seasonal prep service includes cold-start system checks, fuel filter replacements, coolant testing and top-off, battery load testing, and air filter inspection. During winter prep, glow plugs are tested and fuel additives are recommended to prevent gelling. Summer prep focuses on radiator flushing, fan clutch operation, and ensuring cooling capacity matches towing demands.

Prepare your truck for the season with targeted diesel maintenance that prevents breakdowns in Abilene.

How Our Process Works?

You schedule your seasonal prep appointment, and the service begins with a full inspection of systems most affected by temperature changes. In Abilene, winter prep focuses on glow plugs, battery cranking amps, and fuel quality, while summer prep emphasizes cooling capacity, belt tension, and airflow through the radiator.

JR Diesel Performance tests each glow plug for proper resistance, checks battery voltage under load, and inspects fuel lines for leaks or restrictions. Coolant is tested with a refractometer to confirm freeze and boil-over protection levels. Air filters are replaced if dirty, and fuel filters are swapped to prevent contamination during seasonal transitions.

After all checks are complete, you receive a summary of findings, parts replaced, and recommendations for additives or upgrades if you tow heavy loads or drive long distances regularly.
