Water pump replacement explained in 13 easy steps | Gates Europe
Do a final visual inspection to ensure there are no leaks after the cooling system refill. More pronounced seepage and drips from the weep hole after this break-in period or leakage from the mounting surface are abnormal and signal part failure or faulty installation. Keep in mind that some leaks will become obvious when the engine is cold, but others only when it is hot. Cookie disclaimer This website uses cookies to bring you the best visitor experience.

A water pump that is failing causes an engine to overheat.
If a water pump does fail, the damage to the engine could be catastrophic. Therefore, it is important to check the water pump at each service interval. The 'standard time' for installing a belt kit usually includes fitment of a water pump.

A decision to change the belt now, but not to replace the water pump at the same time, assumes that the water pump will last for another complete duty cycle of the belt. Do the job once!
Gates recommends changing water pumps whenever belt kits are fitted and recommends the replacement of old gaskets and seals with new ones. Our water pump kits include everything for a complete drive system overhaul. All Booster Pumps must get there supply from water from a Storage Tank. Booster Pumps cannot simply be put in line with the municipal feed. Please refer to Schematic Drawing of Pump and Tank.
Poor piping design and installation is a common cause of poor centrifugal-pump performance or failure.
INSTALL A SUBMERSIBLE PUMP: 6 Lessons for Doing It the Right Way
Poor piping can result in:. Piping should be at least one nominal pipe size larger than the pump suction Inlet. Suction lines should be short and free of all unnecessary turns. For flooded suctions, piping should be continuously sloping downward to the pump suction so that any vapour pockets can migrate back to the source vessel. For static lifts, the piping should be continuously sloping upward with no air pockets install gate valves in horizontal position.

No non-return valves, strainers or filters are to be fitted between Pump and Tank. The pump already has a non-return valve fitted to it and cannot push back on the Tank. Strainers must be fitted on the pipe work that enters the Tank. Filters can be fitted before entering Tank or on the outlet side of the pump. Make sure that filters can handle the pressure of the pump. When making upstream orientation changes, only long-radius elbows should be used. They should not be connected directly to the pump suction flange, and a minimum of at least two to five pipe diameters of straight pipe should be between the suction flange and the elbow and between successive elbows.
This reduces swirl and turbulence before the fluid reaches the pump. Otherwise, separation of the leading edges may occur, with consequent noisy operation and cavitation damage.

The outlet pipe may be reduced to suit the application. Important to remember the smaller the outlet pipe the less volume of water can be pushed. The Pump must be covered and protected from the elements. Pumps incorrectly installed are not covered under the Manufactures Warranty. This vapor is carried over to the discharge side of the pump, where it no longer sees vacuum and is compressed back into a liquid by the discharge pressure.
This imploding action occurs violently and attacks the face of the impeller. An impeller that has been operating under a suction cavitation condition can have large chunks of material removed from its face or very small bits of material removed, causing the impeller to look spongelike. Both cases will cause premature failure of the pump, often due to bearing failure. In automotive applications, a clogged filter in a hydraulic system power steering, power brakes can cause suction cavitation making a noise that rises and falls in synch with engine RPM.
It is fairly often a high pitched whine, like set of nylon gears not quite meshing correctly. The high discharge pressure causes the majority of the fluid to circulate inside the pump instead of being allowed to flow out the discharge.
As the liquid flows around the impeller, it must pass through the small clearance between the impeller and the pump housing at extremely high velocity. This velocity causes a vacuum to develop at the housing wall similar to what occurs in a venturi , which turns the liquid into a vapor. A pump that has been operating under these conditions shows premature wear of the impeller vane tips and the pump housing. In addition, due to the high pressure conditions, premature failure of the pump's mechanical seal and bearings can be expected.
Under extreme conditions, this can break the impeller shaft.

Discharge cavitation in joint fluid is thought to cause the popping sound produced by bone joint cracking, for example by deliberately cracking one's knuckles. Since all pumps require well-developed inlet flow to meet their potential, a pump may not perform or be as reliable as expected due to a faulty suction piping layout such as a close-coupled elbow on the inlet flange. When poorly developed flow enters the pump impeller, it strikes the vanes and is unable to follow the impeller passage.
