Saw my radiator had coolant on the fins this morning so it def seems like it is leaking. Noticed one of the bolts for the bracket is very weird, it's round and looks like it has a hex engraving but it is not deep at all which has me scratching my head. Is this normal? How exactly is this supposed to be turned? Also if I need to get a new one any suggestions? I have noticed our radiators cost a arm and leg for these small *** radiators. Which I dont get and what's the difference between a 01-06 radiator from ours. Because I found this and these are reasonable.

You remove the bolt from the other side and slide the radiator off that, its just a post to secure your rad.

 

See if a local radiator shop can fix the leaking core. It should be cheaper that getting another one.
