Overheated and now coolant issues

So far it's good. We pressured up to about 8-10 pounds and it was leaking. Just hoping the head gasket is good but with the rad leaking it's pretty hard to test any further

 

I think I had a really small leak in the rad before this happened. Every once in awhile I'd pull away from a stop sign or on a weigh scale and when my fan would kick in in would look like a bit of mist. But i wasn't adding much antifreeze daily so I thought maybe it was dust because I do drive on some gravel roads.
So I'm wondering if it did have a tiny crack already and the pressure just did it in.

 

One of the plastic ones. I found a replacement rad from Star Cooling in Edmonton that are made in Canada for 1200 CAD. Metal rad instead of plastic

 

Lol yeah it definitely pressure tested itself. Fingers crossed that the rad was the weakest point and saved from further damage.
