VAC Moroso E36 M3 Coolant Expansion Tank
Made of aluminum, the VAC Moroso E36 M3 Coolant Expansion Tank is the last coolant tank you will ever need. Perfect for race cars, those that see consistent high temps, or just to look cool under the hood.
Since most E36 M3s have many years ahead and behind them, the plastic, factory coolant expansion tank becomes brittle during the heating and cooling cycles it experiences throughout the years. When you add coolant pressure created by the engine, the brittle coolant expansion tank fails. This is never just a “small” leak, and has the potential to seriously harm your car.
This revision is a direct replacement for the stock E36 M3 coolant expansion tank and 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.
