How to Deal with a Leaking Car Water Pump?

If the monitoring hole of the freshwater pump also leaks, the freshwater pump should be removed from the engine body and disassembled, followed by replacing the water seal. Clean the leaking area thoroughly, then use a metal brush or scraper to completely remove the metal paint and rust.

Last time I noticed a water pump leak in my car, and it felt like a big deal because a faulty water pump can easily cause the engine to overheat, leading to more expensive repairs later. I immediately stopped driving and found a safe place to inspect it. The leak is usually around the pump body or the seal. If a lot of coolant has leaked, adding some purified water can be a temporary fix, but don’t rely on it long-term. It’s best to tow the car to a professional repair shop and have them assess whether to replace the pump or the seal—it usually costs a few hundred bucks, so don’t delay. During regular maintenance, always check the cooling system to avoid issues with older cars, saving both hassle and effort.
