Radiator cap marked OE number 3B0121321 works as a vital pressure control component tailored for VW Sagitar and Audi TT. Mounted on the expansion tank or radiator filler neck, the component seals the cooling system and maintains preset internal pressure to raise coolant boiling point. Stable pressure prevents premature boiling of coolant under high engine load and avoids overheating risks. Built-in pressure valve and vacuum valve release excess pressure and refill liquid automatically with temperature fluctuation.
Worn radiator caps lose sealing capability or fail pressure regulation after long time service. Damaged caps cause coolant loss, frequent overheating and shortened service life of water pump and radiator. Replacement radiator cap adopts high-quality metal shell plus durable rubber sealing ring. Materials withstand continuous high temperature and coolant corrosion inside engine bay. Strict production standards keep opening pressure and thread size fully match OEM requirements.
All finished units pass pressure performance test and visual inspection before shipment. Quick installation needs no modification. Economical aftermarket spare fits auto repair garages, auto parts wholesalers and private car owners. Timely replacement stabilizes cooling system pressure, stops coolant leakage and protects engine from overheating damage for VW Sagitar and Audi TT.
