►Replacing your E46 M3's cooling system components is critical to keeping your engine in good health. The E46 M3 water pump, thermostat, and radiator comprise the core of the cooling system components, and all share a general replacement interval of around 80-100,00miles. Replacing the E46 M3 thermostat, radiator, and water pump is a reasonably involved job but nothing you can't handle at home with a few hand tools. It's also a great time to replace any OE parts with upgraded aftermarket components to bolster the S54 engine's cooling system for intense, spirited driving.

Follow along as Mike Hidalgo, FCP Euro's Professional DIY'er, takes you through an E46 M3 water pump, thermostat, and radiator replacement.
