A vehicle's irrigate pump is a indubitable relevant branch of the vehicle's cooling system. It circulates engine coolant throughout the engine and radiator to remove the excess heat produced by the engine. If this heat were not removed, the engine would overheat and destroy itself. Making sure that the water pump is in good condition and working properly is an important step in keeping the engine from overheating. Water pumps usually give signs of problems.
Instructions
1. Listen to the engine while it is running. Bad bearings in a water pump emit a high-pitched squeaking sound when the engine is running.
5. Remove the water pump from the vehicle by removing the mounting bolts around the exterior edge of the pump. Inspect the pump's impeller for damage. The impeller is used to push coolant through the engine's coolant passages. Leaking ares usually have a creamy-white to rusty-brown color. Also check the seal between the water pump and engine block. Leaks can hide there as well.
3. Look for coolant leaks on the ground where your car is usually parked. This is easier to see on concrete and asphalt than on a dirt or gravel area.
4. Remove the belt that drives the water pump. Shake the water pump pulley from side to side and back and forth. The objective is to see how much the pump shaft will move. If the shaft moves a lot, that is a sign the pump's main bearings are damaged.
2. Inspect the water pump visually. Use the flashlight to check the exterior part of the water pump. Look for wet areas on the pump and signs of leaks. Over time, impellers can become bent due to debris flowing through the cooling system. This is why it is important to have your system flushed.
