I’m using a 1/2 rad from a del Sol for my turbo setup, but I don’t like the way the drain hits the front crossmember. Instead of hammering or cutting away the crossmember to get access to the drain for whenever I need to drain and refill, I was thinking of relocating the drain to the end of the tank. I’ve never taken a radiator apart before so I don’t know if I can simply drill and tap a hole and plug it with a bolt or valve (or something like that).
not worth it. i had the same problem. i put a plug on the drain and when i want to drain it i just unplug the lower rad hose.
