VAC E46 M3 Coolant Expansion Tank
Made of aluminum, this is the last coolant tank you will need to
buy. Perfect for race cars, and others that see consistent high
temps, or just to look cool under the hood.
Since most E46 M3s have many years behind them and many
ahead, the plastic, factory coolant expansion tank becomes
brittle with all of the heating and cooling cycles in addition
to just being plastic and several years old. When you
add the coolant pressures created by the beastly S54 motor, when
the factory, plastic coolant expansion tank fails, it is usually
catastrophic, not just 'a little leak' !!
This revision is a direct replacement for the stock E46 M3
coolant expanstion tanks and it does not use the factory
sensor. Because of this you will need to short the wires
to prevent the "Check Coolant" light on your instrument panel.
