Without the water pump, coolant can’t circulate properly, and that can quickly lead to overheating and severe engine damage. If your pump is leaking or worn, replacing it should be a priority to avoid expensive repairs.

Everything to Know About Replacing Your Water Pump

How to Replace the Water Pump in Your Subaru Forester

6. Reassemble and Refill

Reinstall belts, reconnect hoses, and refill the cooling system with fresh coolant.
