I have a slow leak... low coolant light comes on about every 2 to 3 weeks. it seems to be leaking around the metal clamp that gm decided should go on a PLASTIC radiator top!!! no cracks or anything seen but it just slowly seeps out (from what i can tell)... anyone every taken the top off the radiator and checked the seal on that? ever used any radiator stop leak? i'm willing to try anything before taking it into the freakin dealer.... this should be a recall, but its not!
