Replacing components with the timing kit with water pump guarantees durability and performance of the entire transmission system. The engine cooling system stabilises the engine operating temperature by limiting the rise above the expected limits. The coolant is circulated by the water pump, which must ensure the correct flow at each engine speed. Incorrect operation of the water pump can cause significant damage to the engine. For this reason it is extremely important that it is systematically checked. In many applications, the water pump is controlled by the timing belt. Therefore, its control and any replacement during maintenance to timing control system is extremely important.
The elements of the Timing Kit with Water Pump
The Water Pump
The major elements that characterize the quality of Dayco water pump are:
- The bearing: supports the impeller on one side and the pulley on the other side. This element must ensure constant smoothness and withstand the loads generated by the system. It can be a double ball bearing or single ball bearing (impeller side) and a roller bearing (pulley side). The determination of the bearing geometry is made by the engine manufacturer according to the loads generated by the system.
- The impeller: can be made of synthetic material reinforced with fibreglass, steel or cast iron. The profile of the impeller blades is important, because it must ensure the correct flow and avoid cavitation effects. The design of the impeller is complex as it ensures constant flow of liquid at all engine speeds.
- The seal: mounted between the impeller and the bearing. The seal must ensure that the liquid is sealed at all operating temperatures and speeds. The aim is to prevent liquid from entering the bearing and compromising the quality of the grease, damaging the pump.
- The pump body: generally made of plastic or aluminium. The pump body must guarantee the correct stiffness and geometry of the system.
The other elements
The kit contains the following elements:
- Timing belt
- Idler pulley
- Accessory kits
The water pump in the kits is an original equipment derivation pump, offering maximum safety and durability as required by manufacturers.
