Diesel Service Technicians and Mechanics

Diesel service technicians and mechanics inspect, repair, and overhaul buses, trucks, heavy equipment, and vehicles with a diesel engine. They may also work on a vehicle’s electrical system and install emission control systems to meet pollution regulations.

Routine maintenance from a reputable diesel shop can help extend the life of your diesel truck. Look for Diesel Pro LLC repair shop that specializes in your specific type of truck.

The cylinder block is the bedrock of the engine, housing critical components like the cylinders, pistons and crankshaft. It’s made from sturdy iron or aluminum alloy and designed to withstand the intense heat and pressure generated during internal combustion.

The bottom half of the cylinder block houses the cylinders, which are sealed with a ‘head gasket’. The head sits on top of the cylinders and contains valves and spark plugs that control air and fuel intake. Coolant and oil pass through the head and block, regulating temperature and lubricating moving parts.

A faulty block can cause several major problems. Visible cracks or warping are clear signs of trouble, but other symptoms include excessive engine overheating and oil pan leaks. Coolant leaking from the block and mixing with engine oil can lead to milky or frothy appearances on the dipstick or in the oil filler cap. Persistent engine knocking can indicate damaged cylinders or other issues with the block’s gasket sealing and compression.

Engineered to withstand the high stress, friction and vibration of internal combustion engines, a cylinder block must be properly machined in order to optimize its performance. The quality of the block’s design and materials, as well as the precision with which it is machined, have a direct impact on engine power and efficiency.

A faulty block can cause serious damage to the engine and may need to be replaced, but Stang Auto Tech is here to help!

Fuel System

The fuel system is responsible for storing and supplying your vehicle with the combustible materials it needs to generate power. Gasoline or diesel fuel is stored in the fuel tank, drawn up by a fuel pump and sent through a fuel filter or fuel injectors for injection into the engine’s cylinder chamber. The fuel pump also controls the pressure that the fuel is delivered at, keeping it in the optimal range for combustion.

A fuel system that is not working properly can result in poor performance, a failing engine, and even an outright breakdown. Some symptoms to look out for include difficulty starting the car, a strong fuel odor, or leaking fuel components. When these issues arise, it is important to address them promptly to prevent further damage and extend the lifespan of your diesel vehicle.

When the fuel system is working correctly, your diesel vehicle will run smoothly and efficiently. During the diagnostic process, a technician will inspect the entire fuel system for signs of leaks or restrictions. This will involve using advanced tools and techniques, such as a fuel flow test or an electrical resistance assessment of the injectors.

A faulty fuel injector can cause your engine to run poorly and use more fuel than necessary. This can result in a higher fuel bill than normal and decreased performance. Fuel injectors are a complex component of your diesel engine, so it is important to trust a professional when addressing any fuel system problems.

Whether you have a conventional carbureted diesel engine or a modern multiport Electronic Fuel Injection (EFI) diesel engine, your fuel system is critical to your engine’s performance and longevity. To ensure the optimum functionality of your fuel system, consider incorporating regular fuel additives that can improve lubrication, reduce deposits, and prevent corrosion in your fuel line components.

The fuel system of your diesel truck is an intricate and complex network of mechanical and electrical components. As a result, it can be more prone to electrical issues than other vehicle systems. These problems are usually the result of burnt or damaged wires that lead to one of the fuel system’s key components. For this reason, a thorough fuel system inspection is essential to finding and fixing any problems with your fuel system before they become serious or costly.

Fuel Injectors

Fuel injectors are a vital part of your engine. They deliver the air and fuel your engine combusts to create power. If the fuel injectors are clogged, it can cause problems with the overall performance of your engine. Fortunately, there are ways to diagnose and address the problem before it becomes worse.

If your car is experiencing symptoms like poor acceleration and decreased fuel efficiency, it could be a sign that the fuel injectors are clogged. Fuel injectors spray the fuel into the engine to create the proper air-to-fuel ratio for combustion, but the injectors can become clogged with dirt and contaminants over time. This can cause the engine to run lean and can also burn out a piston if the problem is not addressed quickly enough.

A common way to test whether your fuel injectors are working properly is to check for a consistent spray pattern. A clean fuel injector will spray the same amount of fuel in a consistent manner regardless of the throttle position, but a dirty fuel injector may spray too much or too little fuel. Another sign of a failing fuel injector is if you are experiencing engine hesitation or stuttering. A clogged fuel injector will starve one of the cylinders of fuel and can cause the engine to lose power.

There are a few things that can cause your fuel injectors to become clogged, including dirt and debris that gets into the nozzle orifice, carbon buildup on the injector plunger, wear on the needle or other issues within the injector body. You can try to clean your fuel injectors at home using a special injector cleaner, but it is usually best to have a professional take a look at them. A professional will be able to use more advanced equipment to remove stubborn deposits and restore the injectors to a clean state.

It is important to perform routine maintenance on your diesel engine, which includes regular oil changes and the use of fuel injector cleaner. A well-maintained engine will last longer and run more efficiently, so it is worth the investment.

Transmission

The diesel transmission takes the power from your engine and sends it to the drive wheels. This hard-working system is crucial to your vehicle’s overall performance and reliability, but like any mechanical component, it can develop issues over time.

Fortunately, a trained diesel mechanic can identify and repair many common transmission problems to ensure your truck keeps running smoothly. One of the most common indicators that your diesel transmission is in need of service is strange noises while shifting gears or during acceleration. These sounds can indicate that the transmission is shifting gears unevenly or that the transmission clutches are worn out.

Another sign that your diesel transmission needs service is when it starts to shift gears without your input. This issue may be caused by low transmission fluid levels or a problem in the hydraulic system. The diesel mechanic will inspect the transmission to determine the cause of the issue and then replace or repair the parts as needed.

The transmission fluid in a diesel vehicle is essential for keeping the system lubricated and functioning properly. Over time, the fluid can become contaminated with debris and lose its effectiveness. Regular transmission fluid changes can prevent this issue, and using the right type of fluid is important for ensuring that the diesel transmission remains dependable.

Modern diesel transmissions use complex electronic controls to help coordinate the mechanical and electrical components of the vehicle. As such, these systems are prone to a number of different problems that can affect the transmission’s function and performance. Diesel technicians can use advanced diagnostic tools to assess the transmission’s electronic components and identify any potential problems.

The diesel technician can also check the lead/acid storage battery to see if it is faulty or broken. If the battery is faulty, it will need to be replaced. This is a quick and easy fix, and the diesel technician can usually complete this job at their shop. The diesel technician can also look at the transmission’s fluid levels to ensure they are correct and free of debris. They can also look for signs of overheating and sensor malfunctions.
