but it's probably got an auxiliary drive belt, which is the now correct term for what used to be called the fan belt when engines were predominantly longitudinal rather than transverse, and the fan was therefore rotating in the same axis as the engine crank, so could be driven from the engine directly.
now the auxiliary drive belt drives such things for example as air conditioning compressor, power steering pump, water pump, alternator and so on. This list is a generalisation and neither make nor model specific.
