Water Pump

Water Pumps

A water pump is a device that circulates water through a system. In an automotive engine, the water pump circulates coolant through the engine block and radiator to keep the engine at a safe operating temperature. Water pumps are typically belt-driven, and they can be either mechanical or electric.

Mechanical water pumps are driven by a belt from the crankshaft. They are the most common type of water pump, and they are typically used in older vehicles.

Electric water pumps are driven by an electric motor. They are becoming more common in newer vehicles, as they offer better efficiency and performance.

Water pumps are an essential part of an automotive engine, and they play a vital role in keeping the engine cool. If a water pump fails, the engine can overheat and damage itself.

Types of Water Pumps

• Mechanical water pumps
• Electric water pumps

Symptoms of a Bad Water Pump

• Overheating engine
• Steam coming from the radiator
• Low coolant level
• Worn or damaged water pump belt

How to Test a Water Pump

• Visually inspect the water pump for leaks.
• Check the coolant level and make sure it is full.
• Start the engine and listen for any unusual noises coming from the water pump.
• Feel the water pump housing for any hot spots.
