All components are corrosion-resistant and built to withstand high heat and pressure environments commonly found in diesel applications.
Installation. Installation is easy and can typically be completed with standard hand tools. The kit is designed to be a straightforward, bolt-on upgrade without the need for cutting or modification.
Warranty. This Coolant Bypass Kit is backed by a limited lifetime warranty for long-term reliability and peace of mind.
