Coolant Reservoirs: AWE ColdFront for Audi B8

The coolant reservoir, or expansion tank, holds extra coolant and lets the system manage pressure as it heats and cools. Factory plastic tanks become brittle with age and heat, and a cracked tank can leak coolant and lead to overheating. An upgraded reservoir is a reliable fix on cars known for tank failures and a clean look in the engine bay.

This collection features the AWE ColdFront Reservoir for the Audi S4 and S5 B8 with the 3.0T supercharged V6. It replaces the factory coolant expansion tank with a more durable AWE design built to handle the heat of the supercharged engine and the repeated pressure cycles that wear out factory tanks. It is a smart preventive upgrade for any B8 S4 or S5 owner, and a natural addition when doing other cooling system work.
