COOLING SYSTEM

Overheating; probably the most feared occurrence in a amateur motorist’s life. Tales of headgasket failure, clouds of steam and inevitable catastrophic engine failures surround the world of modified cars in particular, simply because people don’t pay as much attention to the cooling system as they should do.

Heat exchangers are implemented in almost every cooling area of a car’s setup, be it the main radiator for the engine or smaller intercoolers used to take heat from oil and water used to cool and lubricate ancillary components like turbochargers and superchargers.

Keeping your engine and powertrain cool is essential due to the damage that can occur when certain areas become too hot, especially gaskets and seals. All it takes is for one gasket to fail, water to enter somewhere it shouldn’t (like a cylinder) and you’ll be breaking your car for parts in no time. So considering car companies spend millions on research and development of their car’s cooling systems, precautions should be taken especially if you plan on modifying your car. As you can see from the previous equations, an increase in power means that a larger amount of heat energy needs to be dissipated to the surroundings, thus meaning that the cooling system must also be modified accordingly.
