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.
PRECISION ENGINEERED FOR
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 to stay beautiful, year after year.
