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.
Additional information
The elements of the Timing Kit with 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
- Tensioner
- 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.

The Poly-V belts are produced for auxiliary transmissions of cars, commercial vehicles, heavy duty vehicles and buses. Service belts control almost all auxiliary systems. They have very important functions controlling the correct operation of
- The climate control compressor
- The power steering pump
- In some cases even the water pump
- The alternator
Additional information
The Poly-V belt and the A/C compressor
The Poly-V belt, with a pulley system, powers the air temperature control system compressor. Its task is to compress the coolant gas circulating within the air temperature control system. It is recommended to always keep the service belt in perfect working order, especially in summer. The functioning of the air temperature control system also depends on this.
The Poly-V belt and the power steering pump
The Poly-V belt powers the power steering pump. The latter is present in almost all cars, ensuring smoother and safer driving. A malfunctioning service belt can make the steering system barely manoeuvrable, compromising the safety of all passengers on board.
The Poly-V belt and the water pump
On some types of cars, the service belt operates the water pump, ensuring the circulation of coolant within the cooling circuit. Thanks to the water pump, the engine and its components can remain at an optimal temperature. Without it, the engine would emit very high temperatures, causing malfunctions.
The Poly-V belt and the alternator operation
The main characteristic of the Poly-V belt is that it powers the alternator by recharging the battery that operates:
- Starting of the engine
- The dashboard control panel
- The headlights
- The electric windows
- The air temperature control system.
Materials
Dayco Poly-V belts are all made of EPDM (Ethylene-Propylene-Diene-Monomer) and guarantee:
- Excellent resistance
- Reliability
- Silent operation
- Long service life.
Main features of the Poly-V belts:
- Highly flexible for use on small diameter pulleys
- Power transmission also with the back of the service belts, in the case of the “DPK” (Double Poly-V)
- Resistance to high operating temperatures for longer service life
- Managing high workloads while maintaining consistently high performance
Poly-V replacement
Replacing the Poly-V belt requires technical equipment and vehicle knowledge typical of technicians or those who know mechanics. Attention must be paid to the correct tension to be applied to the service belt and the correct positioning on the pulleys. In any case, the best is to turn to a trusted mechanical technician. For this type of operation, it remains the best choice.
