A belt or hose failure can cause an overheated engine, loss of power steering, and loss of the electrical charging system. If a hose leaks coolant or the belt turning the water pump snaps, the cooling system is inoperable. If the engine overheats, it can suffer serious internal damage that requires expensive repairs and can ruin a summer vacation.
Overheating can occur anytime, but usually happens in the summer. Underhood temperatures are much higher, and heat can trigger or accelerate deterioration of rubber compounds.
Many of the same elements that attack hoses also attack belts—heat, oil, ozone, and abrasion. Almost all cars and trucks built today have a single multi-grooved serpentine belt that drives the alternator, water pump, power-steering pump, and air-conditioning compressor. Older vehicles may have separate V-belts that drive the accessories.
