At Amin Auto, we offer expert cooling system repairs for diesel engines in London, Ontario, helping you maintain optimal engine temperature, performance, and long-term reliability. Diesel engines generate significant heat under heavy loads, making the cooling system essential for preventing overheating, breakdowns, and serious engine damage.
If you’ve noticed temperature spikes, coolant leaks, or your engine running hot, it’s time for a professional inspection. Our experienced technicians are trained to handle the complexities of diesel cooling systems and provide accurate diagnostics, reliable repairs, and preventative maintenance to protect your engine and maximize its lifespan.
Whether you’re bringing your vehicle in for diesel engine diagnostics, DPF cleaning and replacement, or emissions service, we’ll inspect the cooling system to ensure it’s performing correctly under all driving conditions.
Why Diesel Cooling Systems Need Special Attention
Diesel engines operate at higher pressures and temperatures than gasoline engines. This makes them more demanding on cooling systems, especially in heavy-duty applications or long-haul driving.
Key components include:
- Radiator and cooling fan
- Water pump
- Thermostat
- Coolant reservoir and hoses
- EGR cooler and intercooler (in many models)
Any malfunction in these components can lead to overheating, cylinder warping, or complete engine failure. That’s why timely cooling system repairs for diesel engines are essential.
Our Diesel Cooling System Repair Services
At Amin Auto, we provide comprehensive cooling system services for diesel vehicles, from light-duty pickups to commercial diesel trucks.
1. Cooling System Diagnostics
We begin by performing:
- Coolant pressure testing
- Thermostat operation checks
- Radiator and hose inspections for leaks
- Temperature sensor readings
- Water pump functionality evaluation
We also look for signs of oil or combustion gases in the coolant, which may indicate a deeper issue.
2. Radiator and Hose Repairs
Leaks or clogs in the radiator or coolant hoses reduce system efficiency. Our services include:
- Radiator flush and replacement
- Upper and lower hose replacement
- Pressure cap testing and replacement
- Radiator fan motor and switch repairs
3. Water Pump Replacement
A failed water pump can prevent coolant from circulating, quickly causing engine overheating. We provide:
- Pump removal and installation
- Belt and pulley inspections
- Seal and gasket replacements
4. Thermostat and Sensor Replacement
If your engine runs too hot or too cold, a stuck thermostat or faulty sensor could be the cause. We repair or replace:
- Engine coolant temperature sensors
- Thermostat housing and thermostat unit
- Electrical connections to the ECM
5. Diesel-Specific Cooling Components
Diesel systems often include EGR coolers, intercoolers, and turbo-related cooling. We inspect and repair:
- EGR cooler leaks and failures
- Charge air cooler and intercooler issues
- Turbo cooling line leaks (if applicable)
These components often work in conjunction with others, so we may also recommend related services like turbocharger repair and replacement or glow plug testing and replacement to ensure full system performance.
Signs Your Diesel Cooling System Needs Repair
If you notice any of the following symptoms, schedule service immediately:
- High engine temperature or overheating
- Low coolant warning light
- White exhaust smoke (indicating coolant entering combustion)
- Visible coolant leaks under the vehicle
- Heater not working in winter
- Engine fan constantly running
Ignoring these issues can lead to major engine damage. For full system recovery, we also offer high-pressure fuel pump repair and DEF system repair to cover all emission and performance systems.
