Matching Numbers Water Pump Rebuilding Service:

When Rebuilding the original is the best way to go!

A multitude of decisions must be made whenever the restoration of a classic or muscle car is undertaken. In most cases, choosing to rebuild individual parts rather than to replace them is the best course, especially when conducting a true restoration when correctness and originality are considerations. This is especially true when the car being restored has nearly all its original parts still intact. At Crown Auto Parts & Rebuilding we specialize in rebuilding matching numbers parts for classic cars and trucks to help you keep that classic matched and on the road to handle today's modern fluids.

The water pump is the heart of the cooling system. The pump circulates coolant between the engine and radiator to keep the engine from overheating. Inside the pump is a metal or plastic impeller with blades that push the water through the pump. The impeller is mounted on a shaft that is supported by the pump housing with a bearing and seal assembly. Water pumps typically fail one of two ways: the shaft seal starts to leak, or the impeller inside breaks, comes loose or the blades erode and wear down.

When a water pump starts to leak, the cooling system will lose coolant. If the leak is not discovered, the loss of coolant will eventually cause the engine to overheat. If the engine has overheated, the entire cooling system (radiator, hoses, water pump and engine) must all be inspected to see if there are any coolant leaks. If coolant is leaking out of the water pump shaft or vent hole, the water pump needs to be replaced or in our specialty, REBUILT! Cooling system sealer cannot stop this kind of leak.

Sometimes a water pump will fail internally due to severe corrosion wearing away the impeller blades, or the impeller comes loose on the shaft, or the shaft itself may break from metal fatigue (caused by flexing due to an out-of-balance fan). If this is the case it's time to rebuild your original matching numbers water pump.

Original water pumps were made specially for the engine size, vehicle type and option it came with from the factory. Over the counter water pumps are made to fit a several years of different vehicles engine sizes and time frame. By rebuilding your original matching numbers and date coded water pump you are assuring yourself that the correct fitment goes right back where it started.  One of the key points in rebuilding your OE part.  Never surrender the original! Rebuild it professionally.

If you have purchased a New Old Stock (NOS) water pump from ebay, it is recommended that it be rebuilt before attempting to use it.  We are always here to help.
