How Does Heat Build-Up in an Internal Combustion Engine?

Most drivers do not understand the intricacies of heat build-up in an internal combustion engine. First, any driver should know that an internal combustion engine is a closed system where intense fire builds temperatures as high as 2,000 degrees Fahrenheit, no matter if you are driving downtown or elsewhere. Pistons are immediately exposed to these temperatures. Fortunately, that exposure lasts only a microsecond. Otherwise, the aluminum pistons would melt.

The heated piston is cooled by a system where the cylinder in which the piston travels is immersed in a liquid coolant to whisk away the excess heat through the metal of the cylinder during the remaining stroke. As your engine runs, the liquid coolant heats up. To remove the heat, your water pump continuously moves the coolant to avoid overheating.

At Harris Porsche, check your fluid, thermostat, and water pump during each service.
