Description
OEM number 443121321, Audi / Volkswagen, Audi 80 / 90 / 100 / Volkswagen Golf / Jetta / Passat, coolant expansion tank pressure cap, genuine used and tested.
This coolant expansion tank cap closes the coolant reservoir on the Audi 80, 90 and 100 and the Volkswagen Golf, Jetta and Passat, maintaining cooling system pressure under normal operating temperature and releasing pressure at the calibrated threshold through the built-in pressure relief valve.
A worn cap that does not hold the correct pressure can cause coolant loss from the overflow, reduce the effective boiling point of the coolant and lead to premature overheating, particularly in warm ambient conditions or under heavy engine load.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
