About this Water Pump
The BOSCH 0-392-023-513 water pump circulates coolant through the engine, radiator and heater. If it leaks or stops pumping, the engine can overheat quickly, so water pumps are often replaced preventively on high-mileage cars.
Frequently asked questions
What does a water pump do?
It pushes coolant around the cooling system so heat can be carried from the engine to the radiator. Many modern European engines use electric water pumps, and some also have an auxiliary pump for the heater or turbocharger.
What are the signs of a failing water pump?
Coolant leaking from the pump or its weep hole, a whining or grinding noise from a belt-driven pump, the engine temperature rising, heater output dropping, or a warning message from an electric pump.
What should I replace along with the water pump?
Replace the gasket or O-rings and any single-use bolts. On belt-driven pumps it is a good time to replace the drive belt, tensioner and idler pulleys; on timing-belt-driven pumps, replace the pump with the timing belt.
How do I refill and bleed the system?
Fill with the coolant your car's manufacturer specifies and bleed the air out following your car's procedure. Cars with electric water pumps often need a bleed routine run through the car or a diagnostic tool.
How do I make sure this water pump fits my car?
Compare the part numbers listed on this page with the number on your old part or in your vehicle's parts catalog, and check the fitment information. If you are unsure, contact us with your VIN before ordering.
