GPU AIO hybrid cooler unit repair

[scole of TSBT]

I have an EVGA GTX 1080 FE with an EVGA AIO hybrid cooler that has a small coolant leak somewhere. I haven't found where it's leaking from. I only smell it. It's the distinctive anti-freeze smell. I would just replace it but you can't even find a used one any longer. I was considering DIY radiator replacement. Does anyone know of others who have done this or have any advice?

If the leak is in the tubing, you can replace that with little effort. Just have to find the right inside diameter. If the leak is in the rad itself, may want to check out automotive rad repair solutions - external ones. Or even solder could patch it.

I can't see where it's leaking around the radiator. No residue anywhere. Going to open the cover and remove the pump to have a look at that. I'll take another closer look around everything though.
