Emergency Roadside Truck and Trailer Repair Blog

Your semi truck’s engine plays a major role in the success of your operation. When the engine isn't working correctly, your schedule (and bottom line) takes a hit. While some issues start small, ignoring the warning signs can leave you stuck on the shoulder. Here’s a breakdown of common semi truck engine problems and what you can do to tackle them before they turn into bigger headaches. When your truck needs engine repairs in Phoenix, contact Emergency Roadside Truck and Trailer Repair. Overheating Woes Long hauls and heavy loads can push your engine’s cooling system to its limit. Overheating is often caused by coolant leaks, a failing water pump, or a clogged radiator. If you notice your temperature gauge climbing or see steam under the hood, don’t ignore it. Regularly checking coolant levels and inspecting hoses for wear can keep your truck running cool. A full system flush and professional pressure test may be needed if the problem keeps coming back. Injector Trouble Fuel injectors are vital for delivering the right amount of diesel to your engine. When they’re dirty or worn out, you might feel a loss of power, see black smoke, or experience rough idling. Routine fuel system cleaning and using quality diesel fuel can help prevent this issue. If symptoms persist, a technician can test and replace faulty injectors. Turbocharger Failure A turbo that’s lagging or making odd noises is often a sign of trouble. Excessive exhaust smoke or oil leaks around the turbo are red flags. Poor lubrication or debris can damage the turbo’s internal parts. Preventative maintenance like regular oil changes and using proper filters goes a long way. Replacing a worn turbo early can prevent engine damage. Sensor and ECM Malfunctions Modern engines rely on electronic sensors and engine control modules (ECMs). When one of these components fails, you might get error codes, reduced power, or poor fuel efficiency. A diagnostic scan can help pinpoint the problem quickly. Replacing faulty sensors or updating software can restore performance. Oil Pressure Problems Low oil pressure can mean trouble for internal engine parts. It’s often caused by a worn oil pump, clogged filter, or a leak. Don’t ignore the oil warning light, check levels immediately and inspect for visible leaks. Regular oil and filter changes are your best defense.

Spring is the perfect time to get your semi truck in shape for long road trips ahead. With the changing season, your rig might need a little extra TLC to ensure it runs smoothly and efficiently. Below are some essential springtime maintenance tips to help you prepare your semi truck for the open road. When it’s time for a tune-up in Phoenix, contact Emergency Roadside Truck and Trailer Repair. Inspect and Top Off Fluids A good place to start is checking your vehicle's fluid levels. Over the winter, fluids can lose their effectiveness due to cold weather and extended use. Ensure your engine oil, transmission fluid, brake fluid, and coolant are all at the proper levels and in good condition. A routine oil change with high-quality, synthetic oil can work wonders, keeping your engine running cleanly and reducing friction. Check Your Tires and Suspension The rig’s tires and suspension bear the brunt of the road. Check your tires for wear, cracks, or punctures. Underinflated tires can affect fuel efficiency and handling, so adjust the pressure according to the manufacturer’s recommendations. Additionally, examine your suspension system—shocks, struts, and bushings should be in good shape to ensure a smooth ride and to prevent premature wear on other components. Inspect Your Braking System Safety depends on your brakes, so have them checked regularly. Listen for unusual noises or a spongy brake pedal, and examine the brake pads for wear. Addressing any brake issues early can help prevent more costly repairs later and keep you safe on the highway. Schedule a Professional Tune-Up Having your semi truck inspected by a professional mechanic is a wise investment. An expert can identify hidden issues—such as air leaks, alignment problems, or failing sensors—that you might miss. Regular professional tune-ups help extend the lifespan of your vehicle and ensure that everything is road-ready.
