The History of Antifreeze
The history of antifreeze has three main players, one of which may be poised to make a comeback.
What is Antifreeze?
Antifreeze is a chemical additive that is used to lower the freezing point of water. Ethylene glycol has been the dominant antifreeze for half a century, but recent studies are indicating the possible return of a long-forgotten solution to this age-old problem.
What is a Radiator Cooling Fan?
Radiator cooling fans can be either mechanical or electric, and they help push or pull air through the radiator. However, these fans aren’t responsible for the bulk of the cooling that a radiator performs.
What is a Radiator?
Radiators are the components in water cooling systems that actually remove heat from the coolant via the mechanism of convection.
What is a Drive Belt?
Drive belts transfer power from the crank or camshaft to the alternator, air conditioner, and other accessories. The first belts were leather, but they’ve been made from rubber and various polymers since the 1920s.
What is a Thermostat?
The purpose of a thermostat is to regulate engine temperature by controlling the flow of coolant. These remarkably simple components have remained relatively unchanged for almost half a century.
What is a Heater Core?
Heater cores are like tiny radiators that use the hot coolant from your engine’s cooling system to warm up the interior of your car.
What is a Water Pump?
Water pumps have been around a lot longer than the internal combustion engines that they help keep cool.
