If Your Water Pump Needs to be Rebuilt


1. Call us so we can identify which water pump you have.

2. Once identified, we will look to see if we have a reman already in stock.

3. If we have a reman, we will send it to you, and you will send to us the water

pump that needs to be rebuilt. Included on your invoice will be a core charge.

4. If we receive your core within 30 days of the date on the invoice AND the core

is not damaged and CAN be rebuilt, then you will receive a core refund.

5. If we do not have one in stock, then you will just send us yours, we will send

it to our rebuilder, and then return it to you once we have received it.

6. Our warehouse address can be found on our Contact Us page.
