Dayco explains its water pumps

CVW takes a closer look at Dayco’s ability to provide effective engine cooling through its water pumps in order to optimise emissions control.

Although the current Euro VI engine emissions regulations are primarily achieved through the use of exhaust treatment systems, the control of the engine’s temperature remains an incredibly important factor to provide the stability that is required to ensure the process is carried out effectively and the designed emissions reductions are delivered in practice.

The auxiliary drive system and the water pump it powers are, therefore, vital elements within the engine. These must operate correctly to allow the entire unit to work in the optimum temperature window to ensure the inlet and exhaust gases are not unnecessarily influenced by avoidable temperature fluctuations. Only when the overall thermal system is managed effectively will the engine run at its greatest efficiency and its emissions potential be realised.

Dayco, an engine products and drive systems supplier for the automotive, industrial, and aftermarket industries, is a major player in the heavy duty (HD) sector, where it supplies important original equipment (OE) components, such as tensioners, idlers, dampers, and belts to HD vehicle manufacturers (VMs) across Europe and around the world.

The company’s engineering pedigree equips Dayco with the expertise required to design and manufacture the components within the drive system that best suit the needs of the application and work
in unison with the engine’s other crucial elements, including the water pump, to guarantee its thermal management is controlled well.

To ensure the aftermarket has access to the high quality replacement products it needs to enable it to provide a first-class and reliable repair solution, Dayco has introduced six water pumps – produced and supplied to Dayco by the OE pump manufacturer – for the 10.8 and 12.9-litre, MX11 and MX13 engines used in a number of popular DAF applications.

These OE water pumps, which Dayco identifies with the part number prefix DP, cater for two MX11 (DP1979 and DP1980) and four MX13 (DP1975/6/7/8) applications and are supplied with or without speed sensor, in line with the original specification stipulated by DAF.

Steve Carolan, National Sales Manager for Dayco, explains: “By providing the OE water pump for these popular vehicles, we can supplement our existing, premium quality range, and give commercial vehicle workshops and fleet managers the tools they need to compete with the VMs dealer networks.

“These OE water pumps and the existing poly-v belts, tensioners, and idlers in the Dayco aftermarket range allow technicians in the independent sector to maintain this standard. It also ensures these vehicles not only remain reliable for their owners and their customers, but also operating within their intended design criteria, which correspondingly benefits the nation’s overall health.”
