What do they do?

The timing belt keeps the crankshaft and camshaft mechanically synchronized to maintain engine timing.

Whether serpentine, V-belt or fan belt (the belts on the outside of the engine), they all transmit power from the front of the engine to accessories that need to be driven, such as the air conditioning, the charging system and fans.

Radiator and heater hoses carry coolant to and from the engine, radiator and heater core.
