Rejuvenating Old Car Batteries

By David Doyle
The cooling systems of most common HMVs have three basic parts: 1) A water jacket cast into the engine block that surrounds each cylinder with liquid. 2) A radiator where most of the heat from the water is transferred into the air as it flows through the radiator core. This air is either pulled or pushed by the engine’s fan at low speeds or when the vehicle is stationary. or is forced through when the vehicle is driving down the road. 3) A water pump, which is the heart of the cooling system. The pump circulates water through the engine block, where it picks up heat, and then pushes the hot water through the radiator tubes where the heat is transferred into the air. The cycle is completed when the cooled water—which has given up its heat to the air—is pulled back into the engine for another go-around.
