Coolant Reservoir – Volkswagen Touareg 2011 - 2018 (7P0121407B)

This high-quality Teilex coolant reservoir (expansion tank) is a direct replacement for Genuine Part Number Reference: 7P0121407B (also written 7P0-121-407-B or 7P0121407). This is the main engine coolant reservoir, fitted across both V6 and V8 petrol and diesel engine variants. It regulates coolant expansion and contraction as the engine heats and cools, allows trapped air to escape from the cooling system, and maintains correct coolant level and pressure. A cracked or leaking reservoir is a common cause of low coolant warnings and engine overheating on these models.
