Professional Repairs at Mango Automotive & Diesel for Common Diesel Engine Problems

Jesse Jackson • December 6, 2024

Diesel engines are designed to handle demanding work environments and offer superior fuel efficiency and long-term performance. However, like any complex machine, diesel engines can encounter problems over time, especially if they are not properly maintained.


At Mango Automotive & Diesel, our team of diesel mechanics in Las Cruces provides expert repairs that address common engine issues. By offering professional diagnostics and precise diesel repairs, we ensure that your engine runs efficiently for years. This will help minimize costly downtime and improve overall vehicle performance.

Common Diesel Engine Problems

Hard Starting or No Start

Diesel engines rely on a combination of components, such as the battery, glow plugs, and fuel system, to start efficiently. Malfunctions in any of these components can cause difficulty starting or even prevent starting altogether. One common reason for hard starting is a weak battery, as diesel engines require more power to turn over than gasoline engines. Inadequate battery power can hinder this process. Glow plugs also play a vital role, particularly in cold weather, by preheating the engine’s cylinders to aid in fuel ignition. Malfunctioning glow plugs can make it difficult to start the engine in lower temperatures.


Fuel system failures are another frequent cause of hard starts, often linked to issues with the fuel injectors, filters, or pumps. Contaminated fuel or clogged filters can obstruct the diesel flow, making it harder for the engine to start. Our team of diesel mechanics at Mango Automotive & Diesel in Las Cruces is equipped to quickly diagnose and fix these issues, ensuring your diesel engine starts reliably every time.


Engine Misfires

Engine misfires are common issues in which one or more cylinders fail to fire properly. The primary causes of engine misfires include issues with the fuel injectors, worn engine components, and malfunctioning sensors.


Fuel injectors spray the right quantity of fuel into the combustion chamber at the right time. If they become clogged or damaged, the engine will receive an incorrect fuel-to-air mixture, which can lead to a misfire. Another cause of engine misfires is the wearing down of engine components like pistons, valves, and compression rings with time.


In addition, sensor malfunctions, such as issues with the crankshaft or camshaft sensors, can send incorrect signals to the engine control unit, disrupting the engine’s timing and fuel delivery system. When these issues occur, the engine may misfire, leading to poor performance and reduced fuel efficiency. At Mango Automotive & Diesel, our experienced diesel mechanics in Las Cruces can perform detailed diagnostics and resolve the root cause of engine misfires, ensuring smooth operation and better engine performance.


Overheating Issues

Overheating is a serious problem that occurs when the engine's cooling system fails to regulate temperature properly. If left unaddressed, this can lead to severe engine damage. Common causes of overheating include low coolant levels, thermostat failure, and radiator blockages.


A common cause for engine overheating is low coolant. The coolant absorbs the heat generated by the engine and maintains an optimal operating temperature. If there is insufficient coolant, the engine can overheat quickly. This could be due to a leak in the cooling system or simply because the coolant hasn’t been topped off in a while.


A faulty thermostat can also cause engine overheating. The thermostat regulates the flow of coolant to the engine, and if it becomes stuck in the closed position, the coolant won’t circulate properly, resulting in the engine reaching dangerous temperatures. Radiator blockages are another factor. Over time, dirt, debris, and rust can build up in the radiator, preventing proper airflow and coolant circulation.


At Mango Automotive & Diesel, we are experts at diagnosing and repairing overheating issues. From simple coolant leaks to more complicated thermostat or radiator problems, our experienced diesel mechanics restore your engine to safe operating conditions.


Low Oil Pressure

Low oil pressure is a critical issue that can accelerate wear on engine components or lead to engine failure if not addressed. It occurs when insufficient oil circulates to properly lubricate engine parts. Common causes include oil leaks, malfunctioning oil pumps, and worn bearings.

As engine gaskets and seals degrade over time, they can allow oil to leak, reducing the amount of oil available to lubricate the engine and causing a drop in oil pressure. A faulty oil pump can also result in low oil pressure by failing to circulate oil throughout the engine properly. Additionally, worn engine bearings increase the space through which oil can flow, which lowers the pressure within the system. If not addressed, these issues can lead to severe engine damage.

At Mango Automotive & Diesel, our diesel repair team can accurately diagnose the cause of low oil pressure and provide the necessary repairs, from fixing oil leaks to replacing damaged pumps or bearings. Ensuring proper oil pressure is crucial for the longevity of your engine, and we are the diesel mechanics near you who help to keep your diesel engine in peak condition.


Excessive Exhaust Smoke

Excessive exhaust smoke can indicate underlying issues in your diesel engine. The color and type of smoke can provide key clues to diagnose the problem.

  • Black Smoke: This usually means the engine is burning too much fuel. Issues such as clogged air filters, faulty fuel injectors, or over-fueling can prevent complete combustion, leading to black smoke. A malfunctioning fuel injection system can also cause excessive fuel to be delivered, insufficiently mixed with air, and burned incompletely.
  • Blue Smoke: Typically, blue smoke means the engine is burning oil. This can occur when oil leaks into the combustion chamber due to worn piston rings, valve seals, or other engine components. This not only reduces engine efficiency but also leads to increased oil consumption.
  • White Smoke: White smoke often indicates coolant contamination in the combustion chamber, which can happen when a head gasket blows or an engine block cracks. This type of smoke is typically accompanied by a sweet odor and signals a potentially serious issue requiring prompt attention.

At Mango Automotive & Diesel, our team of skilled technicians can identify the cause of excessive exhaust smoke and repair it. With our expert diesel repairs in Cruces, we ensure your diesel engine runs cleanly and efficiently.


Loss of Power

Power loss occurs when the engine fails to reach its full potential, often due to clogged air filters, malfunctioning turbochargers, or exhaust blockages.


Clogged Air Filters: Air filters provide clean, filtered air to the engine. When the air filter becomes clogged, it limits the amount of air entering the engine. This reduces the quantity of oxygen available for combustion and can result in decreased engine power. Regular air filter maintenance and replacement are vital for maintaining engine performance.


Faulty Turbochargers: The turbocharger boosts engine performance by forcing more air into the combustion chamber. If the turbocharger malfunctions, it can lead to reduced air intake and, consequently, a loss of power. Common turbocharger problems include worn bearings, damaged blades, or oil contamination.


Exhaust Blockages: Blockages in the exhaust system, such as a clogged diesel particulate filter (DPF), can also cause a loss of engine power. When the exhaust system becomes obstructed, it restricts the engine’s ability to expel exhaust gases, leading to increased back pressure. This can affect the engine’s efficiency and reduce its power output.


At Mango Automotive & Diesel, we diagnose and repair diesel engine power loss. Our diesel mechanics in Las Cruces can inspect your air filters, turbochargers, and exhaust systems to identify the root cause and provide the repairs necessary to restore your diesel engine’s performance.
