When your diesel engine overheats, it is more than an inconvenience; it is also a warning sign of possible damage. Below, we discuss the most common reasons your diesel engine is overheating and how to prevent them. When you need diesel engine repair in Greenbrier or Springfield, Arkansas, give Custom T Repair a call. Clogged Radiator Over time, debris, dirt, and other pollutants can accumulate inside the radiator, obstructing coolant flow and impeding the cooling process. When the radiator becomes clogged, heat exchange efficiency reduces, resulting in higher engine temperatures. Regular maintenance, such as draining the radiator and looking for blockages, can help prevent this problem. The radiator can also be kept clean by maintaining optimum coolant levels and using high-quality coolants. Malfunctioning Thermostat To maintain appropriate operating temperatures, the thermostat regulates the flow of coolant through the engine, opening, and closing as needed. When the thermostat fails, it might become jammed closed, preventing coolant from properly circulating and causing overheating. It may also become jammed open, forcing the engine to run hotter than necessary, resulting in poor fuel efficiency. Regularly examining and replacing the thermostat as part of routine maintenance can help prevent this problem. Engine Coolant Leak Engine coolant controls engine temperature and prevents overheating. However, leaks can develop because of damaged hoses, gaskets, or radiator components, allowing coolant to escape and lowering system efficiency. When coolant levels drop, the engine is no longer effectively cooled, resulting in higher temperatures and possibly overheating. Engine damage can be prevented by regularly inspecting for signs of coolant leaks, such as puddles under the car or low coolant levels in the reservoir. Damaged Radiator Hose The radiator hoses move coolant from the radiator to the engine. Radiator hoses can decay, crack, or leak after being exposed to heat, pressure, and impurities over an extended period. When a radiator hose is damaged, coolant can leak out, which causes lower coolant levels and decreased cooling system function. As a result, the engine may overheat and damage critical components. Check the radiator hoses for signs of wear, such as cracks, bulges, or soft patches.

The transmission is your semi truck's heartbeat. Below, we discuss some of the top warning signs that your semi truck's transmission may be in trouble. When your truck needs transmission repair in Greenbrier or Springfield, Arkansas, give Custom T Repair a call. Transmission Fluid Leak If you notice red or brown puddles of fluid beneath your truck, it's a clear sign of a transmission issue. Transmission fluid is essential for smooth gear shifts and proper transmission operation, and a leak can cause major problems. The fluid acts as both a lubricant and a coolant, minimizing excessive wear and ensuring proper operating temperatures. A leak jeopardizes these functions, potentially causing permanent damage to the transmission. Strange Noises Strange noises, such as clunking, whining, or grinding, can indicate a variety of concerns, including worn gears, damaged bearings, or transmission fluid problems. Ignoring these sounds may result in more severe damage and might leave you stranded. If your truck is making unusual noises, listen to what they are telling you and bring it in for a professional inspection. Trouble Shifting Gears If your truck has delayed shifts, slipping gears, or rough transitions, it is most likely due to a transmission malfunction. These include worn-out clutches, fluid issues, and internal damage. Ignoring these warning signs has an impact on your truck's performance and, if not addressed, can lead to more damage. Smooth and effective gear shifts are critical to the overall performance of your semi-truck, providing a safe and dependable ride. Issues Accelerating When your truck fails to accelerate or responds slowly to acceleration commands, there are likely underlying transmission troubles. These issues might range from slipping gears to low fluid levels, limiting the transmission's capacity to efficiently transfer power.
