weird overheating issue

[jerry S]

you did change the cap right?

Not yet. I am going to wait and do my autometer install and see what my temps really are before I do anything else. I am pretty much for sure that I will get a bigger fan but I don't know my needs just yet. If I can get by with a 1600 cfm puller, I will do that. If my temps are higher than expected, then I will get a 3300 cfm pusher. But first I will wait and see.

The original post brings up a very good point.

When mounting an aluminum radiator ALWAYS use rubber between the radiator and the mounting points to absorb vibration. Otherwise the aluminum welds will eventually fail and you will have small leaks at first and then big leaks and then gushers and then total failure.
