When you continue driving when your engine's overheating you risk a catastrophic engine failure. It really is a good idea to pull over and let your vehicle engine cool down before driving again. If you add water or coolant, be sure your engine is cool or you risk serious burns
Now there's no way for drivers to know when their water pump will fail – they just wear out. This fellow's water pump replacement was more because his water pump is driven by his timing belt. That requires a lot of hours to get to the water pump and then put everything back on the engine.
A money saving tip from Accurso Automotive Repair is if your water pump is driven by your timing belt – replace the pump when you have your scheduled timing belt replacement. That way most of the work is already done and you don't have to pay for it twice.
