Complete inspection of the fan belts, belt tension components, radiator hoses, heater hoses, and rear heating systems on vans and larger SUV’s. Replacement and adjustment (where applicable) of serpentine belts, v-belts, radiator and heater hoses, and hose clamps.
Importance of Service:
Belts on today’s vehicles (serpentine or v-belt style) are responsible for the operation of the alternator, water pump, power steering pump, air conditioning compressor and is some cases the radiator fan itself. Coolant hoses are responsible for the routing of hot coolant from the engine to the radiator were it is cooled and routed back to the engine to keep it at optimum operating temperature. Heater hoses are designed to take the hot coolant from the engine and route it to the heater core for purposes of heating the passenger cabin air and defrost operation.
What May Happen if The Service is Not Performed:
Belts: Depending on the type of belt, there are several things that could happen from a broken or loose belt and could include the following:
- the alternator could stop operating and cause a dash board light to come on and the battery would lose its charge.
- the power steering may stop working causing the vehicle to be hard to steer especially at low speeds.
- the water pump may stop working and cause the engine to overheat which could cause possible engine damage.
- a belt operated fan would stop cooling the radiator
- an air conditioning belt loss or breakage would cause the a/c system to be inoperative
Hoses: Depending on the type of hose, there are several things that could happen from a old, worn, or inoperative hose.
- a radiator hose that is too soft can implode and cause a blockage of the coolant flow. The hose may bubble and burst and may cause a loss of coolant which would quickly overheat the engine and cause possible engine damage.
- a heater hose can leak, implode or burst causing a no heat in the vehicle.
