Your Mitsubishi water pump is slightly misnamed. At least we hope so. Your Mitsubishi water pump is designed to push coolant around your engine and through your radiator. And the coolant that your Mitsubishi water pump circulates should be a 50/50 mix of antifreeze and water, not just straight water. But old habits die hard, and the Mitsubishi water pump got its name way back when water was all it pushed. Besides, Mitsubishi water pump does sound better than Mitsubishi coolant pump. So, we know we have a Mitsubishi water pump, and we know it keeps your car cool by moving the coolant through the engine. What about failure modes? The Mitsubishi water pump will generally be located on the front of the engine, and your Mitsubishi water pump will usually begin to fail by leaking small amounts of coolant through a weep hole. That leakage indicates that the internal seals in the Mitsubishi water pump have failed, and you'll need to order a new Mitsubishi water pump pronto.
