If there was pink in it before, which is OAT, it's not compatible with ethylene glycol so I hope you flushed it out properly before changing. It's not unusual for the odd leak to appear. I might get shouted down for this, but if the cooling system is in decent order a dose of radweld will usually cure it.
I use a dose of Barr’s Leaks in the cooling system each time I change the coolant. I use a good quality ethylene glycol antifreeze at a 25% mixture.
