The Ford 6.7-liter Power Stroke is one of the toughest engines in the heavy-duty truck market. It pulls heavy fifth wheels, works on farms, runs in commercial fleets, and tackles serious job sites every day across southeast Ohio. But like any modern diesel, it requires specific maintenance, and skipping that maintenance can lead to expensive repairs. Don Wood Ford's certified service department handles every aspect of Power Stroke diesel service for F-250, F-350, F-450, F-550, and F-650 owners.

Why a Ford Dealer for Diesel Service?

Independent shops can handle basic Power Stroke maintenance, but diesel work involves systems that benefit from factory-trained technicians and dealer-level diagnostic tools. Our Ford-certified diesel technicians have access to the same diagnostic equipment Ford engineers use, the latest service bulletins, and direct access to Ford technical support when an unusual issue arises. We use genuine Motorcraft and Ford parts, including the specific oils, filters, and fluids the Power Stroke is engineered for.

For warranty work, recall service, and any emissions-related repair, a Ford dealer is required. Even outside warranty, the technical depth on diesel work usually pays for itself in correct diagnoses and durable repairs.

Common Power Stroke Services We Perform

Oil and Filter Changes

The 6.7-liter Power Stroke uses a specific oil specification (Motorcraft SAE 10W-30 Super Duty Diesel Motor Oil or equivalent) and a sizable oil filter. Our technicians handle the full service with the correct oil and filter. Diesel oil changes typically run on different intervals than gas trucks, and we follow the schedule in your owner's manual along with the recommendation that fits your driving pattern.

Fuel Filter Replacement

The Power Stroke uses two fuel filters that need to be replaced on a regular interval. Skipping this service is one of the most common causes of fuel system damage on Power Stroke trucks. We use OEM Motorcraft filters and follow Ford's recommended replacement schedule.

DEF (Diesel Exhaust Fluid) Service

The 6.7-liter Power Stroke uses Selective Catalytic Reduction (SCR) and requires Diesel Exhaust Fluid to meet emission standards. We top off DEF, replace DEF system components when they fail, and diagnose DEF-related warning lights. If your truck is showing a DEF warning, the countdown to limited speed mode has started, and you should bring it in promptly.

EGR and DPF System Service

The Exhaust Gas Recirculation (EGR) cooler and Diesel Particulate Filter (DPF) are common service points on diesel trucks, especially trucks that idle frequently or run short routes that prevent the DPF from regenerating naturally. Our technicians can diagnose EGR and DPF issues, perform forced regeneration, clean or replace components, and address related codes.

Coolant System Service

The Power Stroke uses two separate cooling systems and a specific Motorcraft coolant. Coolant flushes on a manufacturer-recommended schedule are critical to long engine life. We perform full coolant services with the correct fluids.

Turbocharger Service

The Power Stroke uses a single variable-geometry turbocharger. Issues typically present as low boost, sluggish acceleration, or specific fault codes. Our diesel technicians can diagnose, repair, or replace turbocharger components as needed.

Injector Service

Diesel fuel injectors are precision components and one of the most critical wear items on a Power Stroke. We perform injector diagnostics, balance tests, and replacement using OEM Motorcraft injectors when needed.

Glow Plug Replacement

Glow plugs preheat the combustion chamber for cold starts. Failed glow plugs can cause hard starting in cold weather, which matters in Ohio winters. We test glow plug function and replace them as needed.

Transmission Service

The 10R140 heavy-duty transmission paired with the Power Stroke uses specific Motorcraft fluid. We handle scheduled transmission services, fluid changes, and any required repairs.

Used Super Duty Inventory

If you are considering a Power Stroke truck rather than maintaining one, we regularly stock used F-250 and F-350 Super Duty trucks with the 6.7-liter Power Stroke. Each truck goes through a multi-point inspection by our service team, including a thorough diesel-specific evaluation, before it reaches our used lot.
