Fault you gonna meet when you are using water pump
The water pump is a simple devices, water pump is the heart of the cooling system and continuously keeps the antifreeze/water mixture flowing through the engine, radiator and heater core.
The water pump which is connected to the fan in your car is installed on the front of the engine. In any case, it runs off a drive belt connected to the crank pulley, so there is something wrong with water pump, check the following ones:
l Identify the belt and check it for proper tension and cracks.
1) Tighten the belts by adjusting either the alternator or the idler pulley if it is too loose.
2) Inspect the front of the water pump for leaks of coolant, which is green, or engine oil.
3) Grab the fan and wobble it. If there is play from front to back in the fan, the water pump bearing may be going out.
As is known to all, there is a shaft on which the fan mounts. It drives an impeller, which is inside the coolant passages of the engine. There is an oil passage to the bearing which lubricates it. When the bearing goes bad, the coolant will leak out through the worn out bearing and will drip down the front of the engine. In some cases the impeller will slip on the shaft and the water pump will no longer pump. When this happens the engine will overheat, overheating can be caused by many things but don’t rule out the water pump. In this case the fins may be too worn and not allowing enough circulation throughout the system to keep it cool or the water pump is just leaking past the seal and you have lost too much coolant.
Almost every failed water pump will be the result of a bad bearing. You can hear the bearing squeal when the engine is running, usually. If the belt is tight it is probably a bearing. Listen around to determine that it is not an alternator, power steering pump, or AC bearing that has gone bad. If you see anything leaking out of the water pump housing, it will have to be changed.
Water pumps don’t break as often as they used to, but keeping an eye on your coolant level and changing the antifreeze at the proper intervals will help you eliminate problems to the minimum. A broken water pump will quickly leave you stranded and may cause severe damage to the engine if you try to drive too far without the flow of coolant created by the pump. As always if you are worried about the water pump take it to a reputable garage where they can at least pressure test the coolant system and see if there is weakness in system anywhere.
