STL Diesel • Crystal City, Missouri

Diesel Maintenance & Preventive Service

Maintenance recommendations for Ford Power Stroke, Ram Cummins and Chevrolet/GMC Duramax trucks are based on model year, mileage, engine hours, condition and how the truck is used.

Preventive Maintenance

Maintenance built around the truck, not a generic package

STL Diesel does not use one fixed interval for every diesel. Towing, commercial use, extended idling, short trips, dusty conditions and high engine hours can all change what should be inspected or serviced.

Fuel System Service

Fuel-filter condition, water contamination, supply and injector-related concerns are considered along with the manufacturer maintenance schedule.

Cooling System Service

Coolant type, concentration, contamination, hoses, pressure, radiator condition and operating temperature all matter to diesel engine life.

Engine Oil Service

Oil specification and interval should match the engine and duty cycle. High idle time, towing and severe service may justify earlier maintenance.
