  • The purpose of the Engine Cooling System is to prevent the overheating of your vehicle’s engine. With engine combustion reaching extremely high temperatures, the resulting heat needs to be dissipated. An efficient cooling system is essential to prevent the engine from burning!! Another function of the cooling system is to regulate the temperature inside the passenger compartment, insuring your comfort and that of your passengers.


    On most recent vehicles, the engine cooling system is pressurized. You should not attempt to effectuate maintenance or repair work on the system. Servicing or repairing this system requires specific tools and adequate training. That is exactly what Autotech Performance can do for you!

  • Coolant leaks can occur anywhere in the cooling system. Nine out of ten times, coolant leaks are easy to find because the coolant can be seen dripping, spraying, seeping or bubbling from the leaky component. The first symptom of trouble is usually . But your car may also have a Low Coolant indicator lamp. If you suspect your vehicle has a coolant leak, open the hood and visually inspect the engine and cooling system for any sign of liquid leaking from the engine, radiator or hoses. The color of the coolant may be green, orange or yellow depending on the type of antifreeze in the system. You may also notice a sweet smell, which is a characteristic odor of ethylene glycol antifreeze.

    The main parts of the engine cooling system are the radiator, pressure cap, hoses, thermostat, water pump, fan, and fan belt (except on electric fan engines). The system is filled with coolant, which should be a 50-50 mixture of antifreeze and water. No matter where you live or how hot or cold the weather becomes, the mixture should be maintained the year around.

Thus, it is desirable to have a diesel engine cooling system that overcomes the drawbacks of conventional engine cooling systems. In particular, it is desirable to have a system with the ability to more accurately provide the desired engine coolant and oil cooling, while minimizing the number of components required for the system.
