Vehicle Systems Overview - Belts and Hoses
What are the belt and hoses?
A vehicle’s belts and hoses are essential elements of the cooling, air conditioning and charging systems of the engine. When a belt or hose breaks down it can leave you stranded, so it is important to meet the set replacement intervals recommended in your owner’s manual.
What do belts and hoses do?
The timing belt is a notched rubber belt that allows the crankshaft to turn the camshaft. A timing belt is sometimes called a Gilmer belt or a camshaft drive belt. The camshaft opens and closes the valves in synchronized movement with the engine’s pistons.
Serpentine belts, also known as drive belts, provide power to the air conditioning compressor, power steering pump, cooling fan, air injection pump, and more.
Coolant hoses include the upper and lower radiator hoses plus heater hoses. Some cars include a bypass hose. Hoses provide a flexible connection for coolant flow between the engine, radiator, engine and heating block.
