This rubber cap from Dorman has a 5/8” inner diameter (ID), making it suitable to cap-off 5/8″ hose-barbs and other fittings that are no longer in use. This cap is supplied in Improved Racing’s C7 Corvette factory oil cooler system deletion kit.
- 1 x HPL-1001 – 5/8″ ID coolant barb cap
- 2014+ (C7) Chevrolet Corvette
- 2012-2015+ (5th Gen) Chevrolet Camaro SS / ZL1
- This cap is a sub-component in the C7 Corvette factory oil cooler deletion kit (Part # HPL-1003-KIT). Capping only the radiator hose-barb alone will not delete the factory oil cooler and will leak coolant from the factory cooler.
