John C Garage Coolant Cap Kit For LML Duramax 2011-2016 High Flow Bundle

SKU JCGCoolantCapKit

This cap is made in house using the best materials to ensure no issues down the road. Some manufacturers that other EGR solutions or y bridge kits use a vacuum style cap for the coolant port on the passenger side and those have been notorious for failing and coolant going everywhere. Don’t get caught stranded with a coolant leak by using that supplied cap! I have been using these for over 2 years now and not a single one has leaked or failed.
