A by-product of power is heat, so a high-performance motor needs reliable cooling. Often, the first sign of a failing water pump is an overheating engine that's already caused costly damage to the head gasket. We recommend replacement as part of good preventative maintenance for every E46 M3. Made by HEPU to exacting standards, this water pump comes complete with gasket and o-ring.
Make sure you have enough coolant on hand prior to starting the job. You can find BMW Genuine coolant by scrolling to the bottom of this page.
