High Clearance Radiator Conversion (HCR) - 3.4L V6
$295.00 $335.00
Introducing the BEST cooling system upgrade for 96-02 4Runners & 95-04 Tacomas - the complete, bolt-on HCR kit from Opt Offroad! See below for lead times.
THE PROBLEM: This kit addresses one of the biggest design flaws on our 5VZFE powertrains: the haphazard low-hanging radiator... It extends several inches down past the frame ready to get smacked, while also sacrificing your front end ground clearance and approach angle. Whether you are an off-roader or not, this is simply not a risk worth taking. We have seen many front end collisions (even minor on-road "fender benders") that have left people stranded waiting for a tow... and it was easily preventable. What a waste.
THE SOLUTION: The HCR kit replaces your vulnerable stock radiator with your choice of a Premium OE Replacement or High Performance unit that mounts above your frame rails, where it should have been from the start! All kit options are a complete bolt-on replacement and easy install process. They also all come manufacturers with a proven track record and Lifetime Warranty.
Increased Performance. Higher Clearance. Safer Mounting.
HOW IT SHOULD HAVE COME FROM THE FACTORY.

IMPORTANT NOTES:
-
Coolant-
- Koyo recommends following factory specifications.
- Champion recommends 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 with Champion. 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.
- Fan Shroud- Your factory shroud is reusable for this kit! However, there will be excess length at the bottom. It can be easily trimmed off with a razor blade to match the height of the new radiator, if you prefer. Champion is working on a plug and play option for us.
- Maintenance- Overheating issues can be caused by a number of problems (dirty fluid, broken water pump, fan clutch, thermostat...) so don't expect a nice new radiator to fix your problem if something else is being neglected. Your cooling system is just that, a system. So treat it as such and maintain it!
