This service includes complete disassembly and inspection of the water pump, followed by replacement of the factory impeller with a precision-machined billet unit. All seals, bearings, and wear components are replaced to restore proper function and reliability. Each pump is reassembled to ensure optimal coolant flow, durability, and long-term performance. This service is for Gen 2 and Gen 3-5 water pumps and has a 2-3 week lead time. Once purchased you will need to box up your core and send to A&C so the service can be performed.
