DEF system diagnosis

A diesel DEF system helps reduce harmful emissions from diesel engines. But problems with the system can affect performance and trigger warning lights. Our technicians can diagnose the diesel DEF system to identify issues with the DEF tank, sensors, pump, injector, or related components. If you have been wondering, “What is DEF?” it stands for Diesel Exhaust Fluid. Proper diagnosis helps ensure the system works correctly and keeps the vehicle’s emissions system operating as designed.

DPF cleaning and forced regen

A diesel particulate filter, or DPF, captures soot from diesel exhaust to reduce emissions. Over time, the filter can become loaded with soot and require service. Diesel filter particulate cleaning can help remove accumulated material and restore proper exhaust flow. Cleaning a DPF may involve a forced regeneration when normal regeneration cannot complete on its own. Regular DPF service can help maintain engine performance, fuel efficiency, and proper emissions system operation.

Injector and high-pressure fuel system service

The fuel injector system delivers precisely measured fuel to the engine for combustion. Modern diesel engines use a high-pressure fuel injection system that requires clean fuel and properly functioning injectors. Over time, deposits, contamination, or worn components can affect fuel delivery. Injector and high-pressure fuel system service can help address these issues and support smooth engine operation, proper power delivery, and efficient fuel consumption.

Turbocharger service

A diesel turbocharger helps force more air into the engine, supporting stronger performance and improved efficiency. A damaged or worn turbo can cause reduced power, unusual noises, excessive smoke, or other performance concerns. Our technicians can inspect the turbocharger and related components to determine whether service is needed. When repairing a turbocharger, proper diagnosis is important to identify the underlying problem. Professional turbocharger repair can help restore performance and protect other engine components.

Fuel filter change intervals

A diesel fuel filter helps keep dirt, water, and other contaminants from reaching sensitive fuel-system components. Following the recommended fuel filter replacement interval can help protect the injectors and high-pressure fuel system. How often to change a fuel filter depends on the vehicle, engine, and manufacturer's recommendations. Replacing the filter at the proper interval can support consistent fuel delivery, engine performance, and long-term reliability.

Diesel oil change service

Diesel engines rely on engine oil to lubricate internal components and help manage heat and contaminants. A regular diesel oil change helps maintain proper lubrication and can reduce wear on important engine components. Our technicians can use the appropriate oil and filter for the vehicle based on the manufacturer's specifications. For drivers searching for an oil service near me, Sherwood Ford provides professional diesel oil change service near Edmonton, AB, to help keep diesel trucks and vehicles running smoothly.

Emissions software and recalls

Modern diesel vehicles use sophisticated computer systems to monitor and manage emissions. Emissions management software can control systems such as the DEF system, DPF, and other emissions-related components. Software updates may improve system operation or address manufacturer-released updates. Our service team can also check for applicable recalls and determine whether a vehicle needs emissions-related service. Keeping software current can help ensure the vehicle's emissions systems operate according to manufacturer specifications.

Fuel gelling and winter blend timing

Diesel fuel can become thicker in extremely cold temperatures, a condition known as diesel fuel gelling. Winter-blend diesel is formulated to improve cold-weather performance and reduce the risk of fuel-related problems. Timing the switch to winter-blend fuel is important before temperatures drop sharply. At temperatures below seven degrees Celsius, a diesel engine may need additional time to warm up, and extended idling may not be the best way to reach operating temperature. Proper cold-weather fuel preparation can help support starting, fuel flow, and reliable operation.

DEF freezing and thaw

Does DEF freeze? Yes. Diesel Exhaust Fluid can freeze at approximately 12 degrees Fahrenheit (-11 degrees Celsius). Freezing DEF does not necessarily mean the fluid has been damaged. Vehicles are designed with DEF systems that can thaw the fluid and resume normal operation. In temperatures around -30 degrees, the system may need additional time to thaw after startup. Drivers may also notice that regen behaviour changes while the engine and emissions system warm up. Allowing the vehicle to reach operating temperature can help the DEF and emissions systems function properly.

Block heater use

A block heater warms the engine coolant and engine components before starting, making it especially useful during severe Alberta winters. Using a block heater can make starting easier and help the engine reach operating temperature sooner. A block heater can be particularly valuable for reducing cold-start strain and shortening the warm-up period. Diesel trucks may also take longer to reach the temperatures needed for normal idle and regen behaviour in extreme cold, like what we have in Alberta winters. Plugging in the block heater before a very cold start can help the engine warm more efficiently and support reliable winter operation.
