Radiator?

[Satchmo]

I'm leaking some Antifreeze from somewhere.

Bought the truck a month or two ago, changed oil, did some other work. I took off the cap a couple of weeks ago and it was pressurized (even when cold) some fluid leaked out, but now it seems to keep leaking.

Would a cap suddenly fail like that or is it a rad issue?

Here's some pics.

Radiator caps can fail just like any other part. It doesn't cost much to replace one though.
