Calvin you've only used one radiator all this time?
I bought my car in July 2002 and I think I am on my fourth radiator.
The first burst and failed within 6K miles, under warranty, a common fault.
The second burst about a decade later I think?
The third I still have but one day it was 48' out, I was stuck in traffic, and the asphalt temperature must have been at least 60' and for the first time ever I saw the needle move on the gauge. Never overheated, but it moved up a few mm until I started rolling again.
I went out and bought a larger all-Al radiator and am using that one ever since, and I kept the OEM third radiator in the garage just in case.
