Original quality coolant control valve with OE number 059 121 737AM is a key electronic cooling system component specially matched for Audi Q5 with 3.0T diesel engine. Produced fully in accordance with OEM manufacturing standards, this control valve adopts high-precision internal valve core, durable sealing rubber and stable electronic drive module.
