    Fuel Filter Change

    Diesel engines have two fuel filters: 

    • a primary filter to remove larger contaminants
    • a secondary, finer filter to catch smaller particles 

    Replacing fuel filters at the recommended diesel repair and service times is essential for maintaining your engine’s performance, protecting critical components, and ensuring fuel efficiency. It’s a preventive diesel engine maintenance task that can save you money in the long run by avoiding costly diesel repair and service and improving the overall reliability of your diesel engine.

    Air Filter Replacement

    A clean air filter allows fresh air to flow into the engine. This action is crucial for combustion, as diesel engines require a precise air-to-fuel ratio for optimal performance. 

    The engine has to work harder to pull in air when the air filter is clogged with dirt and debris, reducing engine power and decreasing fuel efficiency.

    Oil Change

    Oil traps and carries away contaminants from your diesel engine, such as dirt, debris, and combustion byproducts. As oil circulates through the engine, it picks up these particles, keeping them suspended and preventing them from causing damage. The longer oil stays in your diesel engine, the less effective it becomes at carrying away contaminants, leading to sludge buildup and engine damage.

    In your diesel engine, oil also works to dissipate heat. Diesel engines operate at high temperatures and generate a significant amount of heat. The oil helps dissipate this heat and prevents the engine from overheating. 

    Over time, oil can break down and lose its ability to do its jobs, causing damage to your diesel engine. Replacing the oil in your diesel engine every six months will keep your engine in tip-top shape.

    Coolant System Inspection

    Having your coolant system inspected through regular diesel repair and service can help prevent and detect problems that could lead to costly replacements.

    A properly functioning coolant system helps regulate your engine’s temperature, preventing it from overheating. When your engine becomes overheated, it can cause damage. 

    Coolant can break down over time and become acidic, leading to corrosion in the engine’s components. Inspections can identify signs of corrosion and prevent further damage.

    Regular diesel repair and service can uncover coolant system leaks, preventing loss and potential engine damage from insufficient cooling.

    Evaporative Emission Control System (EVAP) Inspection

    Regular diesel repair and service and inspection of your diesel engine’s EVAP (Evaporative Emission Control) system can help ensure that your vehicle remains compliant with emissions regulations, operates efficiently, and minimizes its environmental impact.

    Keeping the EVAP system in good condition is essential to responsible vehicle ownership and contributing to cleaner air quality.

    Turbo Housing Inspection

    The turbocharger plays a significant role in improving the performance and efficiency of a diesel engine. It compresses air before it enters the engine’s combustion chambers, allowing for more air and fuel to be burned, resulting in increased power output and improved fuel efficiency. 

    At T&S Automotive, our Turbo Housing inspection checks for general wear and tear of the intake system. We take out the intake to check for damage, cracks, scrapping, and wobble or movement of the fan pump or shaft.

    The wobbling of the fan pump can cause problems in the intake system due to the pressure it can produce while in use. Excessive wobbling of the fan pump can cause the fan to make contact with the sidewall and potentially cause pieces of metal to enter the intake.

    Inspecting your diesel engine’s turbocharger housing as part of regular diesel repair and service is essential to ensure the engine operates efficiently, safely, and reliably.

    Glow Plug Inspection

    Your diesel engine’s glow plug plays a crucial role in ensuring that the diesel engine starts smoothly with minimal cranking wear on the starter. It does this by providing heat.

    Diesel engines rely on high compression and heat generated during compression to ignite the air-fuel mixture in the combustion chamber. In cold temps, the heat generated during compression may not be enough to ignite the diesel fuel effectively. Glow plugs provide supplemental heat to the combustion chamber to assist in ignition.

    Like all diesel engine parts, glow plugs are subject to wear and tear over time. Regular inspection allows you to identify any damaged or worn glow plugs and replace them during diesel repair and service as needed to ensure the reliability of your engine.

    Drive Train Maintenance

    The drive train transmits power from the engine to the vehicle’s wheels. Since diesel vehicles are often used for tough jobs, this power transmission system must be robust and well-maintained to handle the high torque diesel engines generate.

    A well-maintained drive train ensures power is delivered efficiently to the wheels, allowing the vehicle to accelerate smoothly, tow heavy loads, and handle rough terrain effectively.

    It’s essential to follow the manufacturer’s recommended maintenance schedule for diesel repair and service as well as the drive train components to ensure your diesel vehicle’s continued reliability, performance, and safety.

    Belts Inspection

    Over time, belts in a diesel engine can wear out due to the stresses of constantly moving and driving engine components. Inspections can help identify signs of belt wear, including cracks, fraying, or glazing (a shiny appearance), which can lead to belt failure.

    It’s essential to have your belts inspected at regular intervals as recommended by the manufacturer or your mechanic to ensure the reliability and safety of your diesel engine. If any issues are identified during an inspection, promptly replacing the belts during diesel repair and service is important. Doing this will help maintain the proper operation of your diesel engine.

    Tire Inspection

    Many diesel vehicles are designed to carry heavy loads. The tires play a critical role in supporting the weight of the vehicle and its cargo. Regular inspections help ensure the tires are in good condition and can handle the specified load-carrying capacity.

    Diesel vehicles are also often used for heavy-duty jobs, requiring adequate traction for off-road or rough terrain. Proper inspections ensure the tires have sufficient tread depth to provide traction for safe and effective operation.

    At T&S Automotive, we always do a proper tire inspection during your vehicle’s diesel repair and service.
