Racingline VWR19G703 Billet Expansion Cap

The RacingLine Coolant Expansion Tank Cap will keep your coolant expansion tank at its perfect pressure to be sure that your high-performance engine’s coolant system is performing exactly as it should. 

  • The cap's a critical part of your car's cooling system to ensure that correct pressure is maintained, and never exceeded.
  • Older, worn stock coolant caps loose the ability to hold correct pressure to keep the coolant at maximum efficiency.
  • This is an engineered, billet replacement coolant cap to replace the cheap plastic one, with sophisticated internal springing and bleed off. 
  • Don’t confuse this RacingLine full replacement cap with other cheap covers - which simply stick on over the plastic cap. We think your car deserves better than that.


  • Meticulously machined with the latest CNC 5-axis technology.
  • Each cap starts life as a solid billet of aerospace-quality 6061 aluminium.
  • Sophisticated internal Japanese-made springing and bleed off mechanism.
  • Polished, then gloss-anodised in stunning Midnight Black to stay beautiful for year after year.
