As seen on so many NSX, the state of the rad core fins...... Some of the data taken in the past showed that the efficiency dropped like 50% on heavily blocked rad.

For C32B, this will cause issue on really hot summer day on track or twisty mountain road with thin air.

Another Koyo Racing radiator. I don't know how many of them I installed for UK based NSX....

Further inspection revealed that the old radiator was leaking even from the upper forward section.

In fact, the worst leakage was happeing at the bottom forward section that was hidden byt the bodywork.

You won't notice it until you see the coolant on the floor.

The A/C pipe.

Going to wipe it off as the dark light suggets that the compressor oil and refrigerant were splashed in the past and not the actual leakage from the receiver or the condenser fitting.

Still, it's leaking from the compressor and most likely from the bulkhead fitting at the evaporator.
