Faulty water pump: Here’s some important info

Your vehicle’s water pump is the key to making the entire system work. The water pump is located on the side of the engine under the timing belt cover. It gets its pumping power via a belt (engine’s drive belt) that connects it to the alternator. As the belt turns, the pump turns.
In order to run cool on those hot summer days, your engine needs to have a constant flow of coolant supplier from the radiator throughout the engine. The water pump is the primary component responsible for maintaining this flow. When the pump works properly, your vehicle will maintain a consistent operating temperature and run smoothly. A faulty water pump can lead to complete engine failure.

The primary purpose of coolant (antifreeze) is transferring heat and preventing engine damage caused by freezing or boiling. The blades on the pump force coolant to flow through the engine and back to the radiator to be cooled by a forced air-cooling fan.

Common symptoms of having a bad water pump:
1. Coolant leak at the front-center of your car- The water pump is comprised of multiple gaskets and seals that keep coolant contained and ensure that consistent flow of coolant is delivered from the radiator to the engine. Over time these gaskets and seals will wear out, dry up, crack or break. Coolant will then leak and drop to the ground.

2. Water pump pulley is loose and making whining sounds- When you hear a high-pitched sound that comes from the front of the vehicle, this is caused by a loose belt that creates a harmonic buzzing or whining sound as it circulates. The loose belt is commonly caused by a pulley that has become loose or that the bearings that operate with the water pump assembly are wearing out.

3. Engine is overheating- With a faulty water pump, it will not be able to circulate coolant through the engine block. This will cause overheating and eventually additional engine damage like cracked cylinder heads, pushed head gaskets, or burnt pistons (when metal gets hot enough, the pistons can weld itself into the cylinder)

The needle on your temperature gauge will move toward the “H” if the engine is starting to overheat. There is also a warning light on your dashboard that lights up when the vehicle is overheating.

However, it is not advisable to keep on driving with a bad water pump because it can lead to extreme damage. Trust your Audi and VW specialists at V.A.G Spec Centre to take care of your vehicle and to keep it cool!
