Good to hear it's running cooler, the added fuel could have been just enough to help it, even though it's an idle adjustment. You can also help a hot motor with a timing adjustment, so double check that when you get time.
I was going to suggest adding a couple small heater cores behind your front openings to add extra capacity to the system, you could gain a gallon or two of coolant and extra cooling with not much work.
Thank you so much! Yeah, seems the little bit of fuel may have helped, even though it was just at idle. I think I forgot to mention that I also added a bit of coolant to my overflow bottle. That may have also helped a bit.
I love that idea about adding a heater core for cooling. I'm a big fan of practical solutions to things
I'm hoping when I add my heater core back to the circuit it will help.
My new fan is arriving today so that won't hurt either, when I get around to installing it.
Thanks for mentioning timing. I am planning to give it a look as it was last timed when things were running poorly (faulty coil, massive leak at the exhaust manifold), so it definitely wouldn't hurt to check.
