Notes:

Coolant-

• OE Replacement: CSF recommends following factory specifications.
• High Performance: Champion and Cold Case recommend Ethylene-based yellow/green coolant & distilled water only, to prevent premature wear on your radiator. Peak 10X is a great choice, as it is formulated to work with all vehicles and cooling systems, and has been thoroughly tested to work with these all-aluminum radiators. Using other coolant types can potentially affect your warranty. While "Asian Red" and "Toyota Pink" coolants are Ethylene-based, they have been known to cause issues with the full aluminum housings, and are discouraged for this setup.

Body Lifts & Radiator Hoses- If you have a body lift, then the distance between your engine and lower hose has been reduced. You may need to trim some excess length off your new lower radiator hose to accommodate the angle perfectly. You are responsible for ensuring hoses are kink-free prior to filling cooling system or running your engine!

Fan Shroud- Your factory shroud is reusable for this kit! However, there will be excess length at the bottom which can be easily trimmed off with a razor blade to match the height of the new radiator. We are currently working on a plug and play shroud.
