Mopar Water Pumps

Helpful Information

Here are some of the most common questions asked about automotive water pumps.

What does a water pump do on a car?

A car's water pump plays a vital role in its cooling system. It circulates coolant from the car's radiator to its engine block, ensuring the engine stays at a consistent temperature. Modern water pumps are more substantial, but there's a chance for them to break down after several years of use. 

How many years do mopar water pumps last? 

Typically, the service life of most high-quality water pumps should be 60,000 to 90,000 miles with proper care. There are cheaper water pumps for cars that start leaking at as low as 30,000 miles. Experts recommend regularly changing your coolant to ensure a long life span of your car's Mopar water pump. 

How often should you replace your water pump?

There's no concrete answer to how often drivers should replace their vehicle's water pump. Factors such as the car model, weather conditions, and driving behavior affect the water pump's lifespan. 

Typically, the recommended interval for replacement is every 60,000 to 100,000 miles. It’s best to create a scheduled maintenance routine to ensure maximum performance.

What causes water pump failure?

Four common causes of water pump failure include bad seals, loose drive pulleys, broken belts, and corrosion. While it's true that a vehicle's pump can fail over time, it's not common. 

Most of the time, it results from insufficient maintenance. Drivers should periodically drain and change their coolant to keep their pumps in great shape. 

What are the signs of a bad water pump in a car? 

The first sign of a bad pump is leaking coolant. When a pump fails, the coolant leaks from the vehicle gasket. If you notice water pooling under your car, you might need to get your pump replaced—other signs to look out for include squealing noises and an overheated engine.
