The water pump is significant to the engine because it ensures that it doesn't overheat by having coolant travel to the engine's water jacket, and the water pump cover seals the coolant in the water pump.
Water pump cover importanceThe water pump cover is essential to the water pump since the seal keeps any coolant from leaking out of the water pump. The seal also keeps any dirt or debris from going into the cooling system. The water pump cover must be in good working order to prevent the engine from overheating on you. If you notice any cracks or leaks, the cooling system can be compromised.
