Description

WHY CHANGE?
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.
