Since my radiator started leaking, I replaced it with a Zionsville all aluminium radiator. I'm very pleased with the upgrade. There were no fitment issues.
My oil temperatures take significantly longer to get past the first 1/4 mark. Even then, I haven't seen the stock oil temp needle creep up to the middle line. I don't have a water temp gauge, which would tell the full story though.
I'd like to thank George for his recommendation.
