Although the cooling system is not as efficient this way and there may be local steam pockets contributing to that, I've not had any issues whatsoever, despite temps up over 100F outside with the AC running. Baring mountains and other more serious stresses, should the need arise to run without the cap for a while, it seems to be innocuous enough to do so. I'm finally going to have some time Thursday to pull the radiator and get it fixed.

Charley came over and we pulled the radiator and had it fixed at my trusty radiator shop, Mel & Sons in Concord. It was bulging and verified leaking along one side. This is the third and last time for that side tank. The repair ended up OK, but one tab did break. That's why it's the last time. Anyway, if I get another 5 years out of this original radiator I will be happy. Heck, I should be happy it has lasted this long. If I can avoid overheating again, it might last forever.

Charley, thanks for the help!

Hey Bill, this is way off topic but since the thread is winding down, can you indulge a rookie?
I would like to hear this rabbit story.

I was rummaging around on some old threads and there was mention of a rabbit taking off your belly pan off at 150 mph. That sounds like one of those, if I survive this -- it will make a funny story, moments.
Regards.

FWIW, I had replaced the overflow tank and not done a good job of securing the small hose at the bottom of the tank. This caused a small leak at pressure in the cooling system. The car always ran hot when pushed, especially climbing the mountain on the way home....(bout a 1,000 feet clime over a coupe of miles).

NB the car is an 89 GT with a Murph stage II SC kit.

It didn't lose a lot of coolant I added maybe a couple of cups over a couple hundred miles.

I finally fixed the issue, no leaking any more and the car runs NOTICEABLY cooler, even when climbing the mountain on 100 degree days. I can only chalk this up to the integrity of the cooling system.
