Our Stage 1 OEM Cooling System Overhaul Kit for E46 M3 includes all the common preventative maintenance parts to keep your cooling system from failing at an inconvenient time. Unlike our Stage 2 and 3 upgrades, this kit consists of cost-efficient OEM and Genuine BMW replacement components for a 1:1 swap of your stock system. This overhaul service typically needs to be performed at 80-100,000 miles with stock parts due to normal wear and tear of water pump bearings and plastic fatigue on the radiator tanks.

WYIT: This is not all of the parts that could be replaced in the E46 M3 cooling system. There are several other "While You're In There" parts that can also be replaced, including belts, pulleys, fan & clutch, expansion tank, and possibly more. Contact us if you would like to discuss additional parts to possibly include.

Coolant: we do not include coolant/antifreeze in this package even though fresh fluid is required. We do sell BMW coolant, and other brands, but due to shipping costs you may want to source your own coolant locally. Remember to mix coolant with distilled water.
