Repair Cost Guide

Water pump replacement cost
for a Subaru Outback

Replacing the water pump on a Subaru Outback involves draining the coolant, removing accessory belts and covers, and detaching the old pump from the engine block, typically on the front timing cover. The cost is driven by the labour-intensive access, which often requires moving other components, and the use of OEM-quality parts to ensure reliability with the car's horizontally-opposed engine.

Whether the timing belt is replaced concurrently (common on older models)
Shop labour rates and use of OEM vs. aftermarket pump

Can you do it yourself?

Possible with skill — Requires mechanical aptitude, special tools for belt tension, and careful coolant system bleeding.

Tips before you pay

On many 2.5L models, the water pump is driven by the timing belt; replacing both simultaneously saves on future labour.
Use a Subaru-specific coolant to prevent potential head gasket or cooling system issues.
Check the thermostat and related hoses for wear while the system is apart.
