Doesn't your pride and joy deserve better than cheap plastic parts in the engine bay?
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.
Of course, 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 lose the ability to hold correct pressure to keep the coolant at maximum efficiency.
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. This is an engineered, billet replacement coolant cap to replace the cheap plastic one, with sophisticated internal springing and bleed off system.
As you’d expect from RacingLine, it’s meticulously machined with the latest CNC 5-axis technology. Each cap starts life as a solid billet of 6061 aerospace-grade aluminum. It’s then hand-polished, then gloss-anodized Midnight Black to stay beautiful year after year.
