Hello, my name is***** code means you have a large evap leak which would not be related to radiator replacement. This usually means fuel cap, evap lines, or leak detection pump has failed. Do a good visual inspection of evap lines near charcoal canister in rear of vehicle. If everything looks good then next step is to replace fuel cap. If problem comes back your best option is paying a shop to do a smoke test to find the leak, if no leak is found replace the leak detection pump. Let me know if you have more questions or if there is anything else I can do to help. Thanks.
