K-Seal can repair most leaks in your engine’s water pump casing and seals.
The cost of replacing a water pump will vary considerably depending on a number of factors, such as the garage you visit and the car you drive. Although the cost of a water pump will usually be somewhere between $50 and $75, the amount charged for labour will boost the total you pay. Some water pump replacement jobs can cost as much as $500. It’s therefore important to get quotes from a range of local mechanics so you can be sure you’re getting the best deal.
If you want to avoid expensive mechanic bills but don’t have the technical knowledge or experience needed to resolve a leaking water pump in any other way, K-Seal is the option for you – it can fix most leaks in the water pump casing and in the seals.

The water pump ensures that enough coolant liquid is flowing around the cooling system and engine in order to remove sufficient heat to prevent the engine overheating. The higher the load on the engine, the more the pump will circulate in order to deal with the greater levels of heat produced as the engine works harder.
A water pump uses centrifugal force to transfer water to the outside of the system as it spins, which means that it is continuously drawn back through the system. It passes through the engine block, cylinder head and radiator before returning to the pump.
There will always be some water pumps that malfunction unexpectedly for a variety of reasons and therefore have to be fixed or replaced completely. One main issue that can be encountered, and which K-Seal is capable of fixing, is the casing developing a leak. This allows coolant to escape which means it doesn’t circulate through the engine and bring its temperature down.
The reasons why a water pump seal might begin to leak include:
It is inevitable that at some point the polished rubber surface of the seal will succumb to the high temperatures it is subjected to every time the vehicle’s ignition is switched on. Tiny cracks or holes will subsequently develop and let coolant out.
It is possible for tiny abrasive particles to get into the pump and damage the seal, such as in tap water that has been mixed with antifreeze to create the coolant (this is why you should only use soft, distilled water if mixing coolant yourself).
Corrosive inhibitors in the seal plating deteriorate in effectiveness over time and the coolant becomes more abrasive the more it is used, which is why regular flush-and-fills are recommended. As the inhibitors deteriorate and the coolant’s abrasiveness increases, electrolysis on the seal face occurs and coolant is allowed to seep through it.
