GMB Water Pumps - Designed to meet or exceed OEM quality, fit and performance

When it comes to healthy operation of your car, one of the most important things to keep in check is operating temperatures which are controlled by your cooling system. With more than 50 years of experience in the cooling system industry, GMB know what goes into a great quality water pump designed to keep temps within spec throughout a range of driving applications and climate types. With extensive product testing and refinement completed in-house, GMB sell their waterpump range confidently with quality assurance meaning you can buy, install and drive with confidence that your water pump will match or even outperform the original part in terms of fit, quality and performance. GMB water pumps are built without compromise using the finest quality components and materials. Die-cast aluminium, cast iron and forged steel make up the bulk of the body construction while impellers are constructed from pressed steel, cast iron or synthetic resin depending on the application to ensure durability, reliable coolant flow and outright performance. GMB relentlessly test their water pumps in-house for leaks as well as strict dimensional precision to ensure their high-quality castings fit within the tight tolerances required of modern engine bays.

Not sure if your water pump is a due a replacement? There are some tell-tale signs of failing water pumps which will indicate you're due for a replacement. Any combination of these issues can be a result of other cooling system failures, however changing your water pump ensures your cooling system is fully functioning in terms of flow and pressure. For a simple breakdown on some of the typical signs, see below:

• Coolant leak at the front of the engine - On front wheel drive cars, this will be on the side of the engine bay rather than the front. The water pump area is located around the accessory belts or serpentine belt, if you see any coolant leaks from this area then it is likely that your water pump has cracked, warped or the gasket sealing it to your engine has failed.
• Water pump pully is loose or noisy - Any loose rattles or noisy whines from the water pump pulley area indicate that the bearing has failed or impeller shaft has become damaged.
• Engine overheating - A non-functional, damaged or compromised water pump can in many ways cause engine temperatures to rise as you drive. Without the necessary circulation of coolant through the radiator, engine and other cooling system components, hot spots of coolant occur throughout the engine or radiator and can result in serious damage.
