Frequently asked questions about water pump repairs

How much is a car water pump?

The cost of a car water pump varies due to the cost of the pump itself, and labour involved for installation. We recommend getting a few quotes from different suppliers to better understand the cost you might expect to pay.

Can you still drive a car with a bad water pump?

If your water pump isn’t working correctly, try not to drive your vehicle until it is fixed. A failing water pump can lead to engine overheating, which can cause severe damage. If you suspect your water pump is failing, it’s best to have it inspected and repaired as soon as possible.

What are the symptoms of a bad water pump?

Symptoms of a bad water pump include coolant leaks, an overheating engine, a whining noise from the front of the engine, steam from the radiator, and consistently low coolant levels. If you notice any of these symptoms, get your water pump checked by a professional.

What happens if a car water pump fails?

If a car water pump fails, it can lead to your engine overheating. This can cause significant damage to your engine, resulting in costly repairs or even complete engine failure. It’s important to address any issues with your water pump as soon as you’re aware of them to avoid serious damage to your vehicle.

How often should the water pump be replaced?

Water pumps typically last between 60,000 and 100,000 miles. However, it's best to follow the manufacturer's recommendations for your specific vehicle. Regular maintenance checks can help identify potential issues early.

Is it necessary to replace the timing belt when replacing the water pump?

The timing belt often needs to be removed to access the water pump, and replacing both at the same time can save on labour costs and prevent future issues. While not strictly necessary, it is a cost-effective way of keeping your car in good condition.

How long does it take to replace a water pump?

Replacing a water pump can take between 2 to 4 hours, depending on the make and model of your vehicle. More complex vehicles may take longer.

Replacing a water pump can be challenging, especially for those without mechanical experience. We recommend you employ a professional mechanic to perform the replacement and make sure it’s done correctly and safely.

Is the water pump covered under warranty?

Whether your water pump is covered under warranty depends on the terms and conditions. It’s best to check with your vehicle's manufacturer or warranty provider for details.

Can a bad water pump affect the heating system in my car?

Yes, a bad water pump can affect your car's heating system. The water pump is responsible for circulating coolant through the engine and heater core. If the pump fails, it can mean that not enough coolant flows through the engine, causing the heating system to function improperly.

Is it necessary to use a specific type of coolant with a new water pump?

It’s important to use the coolant type recommended by your vehicle's manufacturer. Using the right coolant helps to make sure optimal performance and longevity of the water pump and cooling system. Always check your vehicle's owner manual for the recommended coolant type.
