Bluebee, the classic crack is exactly where the UPPER Hose joins the radiator.
This is the area where the plastic neck (the hose attaches here) joins the plastic side tank.
The problem is: it may leak slowly, giving you time to fix, or it can erupt like a volcano with no warning.

Some people have crack radiator at 60K, some runs all the way up to 160K or so.
I am like Mack, stay on the conservatibve side, and replace the rad at 80-100K, considering that an overheated engine will cost you some $4-5K bones!
