Your radiator stores the coolant your engine needs to maintain proper operating temperature, but it wouldn't be going anywhere without your Jeep water pump. The Jeep water pump is an essential part of your vehicle's cooling system. The function of the Jeep water pump is to keep the coolant circulating throughout your engine while your vehicle is running. Without a working Jeep water pump, your coolant would just sit in your heads and engine block, getting hotter and hotter. When the coolant does not circulate to the radiator, the temperature rises tremendously. The overheating caused by a faulty Jeep water pump can cause excessive wear and tear on your engines, warped heads, or even blown head gaskets. The most common problems with the Jeep water pump are leaking and failure due to other engine problems. When your Jeep water pump is leaking, you will find that you have to add coolant to your system much more often than usual, since the coolant is simply emptying from the pump. It is possible to just keep adding coolant, but the leak will just get worse and eventually the Jeep water pump will fail altogether. The best solution for a leak is to replace your Jeep water pump. Problems with other areas of your engine can also lead to Jeep water pump failure. No matter what the cause, if your Jeep water pump is no longer working, it must be replaced immediately to prevent extensive damage caused by overheating.
