Leaking of Coolant

Many water pumps have drain holes in front of the seal, if the seal is broken, coolant will leak out from the drain holes.

When you open the cover and start the car, if you hear a low friction noise, maybe the water pump bearing is going to be broken.

If the circulating coolant is insufficient due to leakage or water pump failure, the engine temperature will rise and the overheating warning light will turn on.

White Smoke From The Radiator

The steam in the radiator is produced from an overheated engine, which can happen if the water pump is not working perfectly.
