As usual, what was supposed to be a quick process has turned into a month long journey.
First up, after looking at my M24 all aluminum radiator I noticed some surface spots. Initially I thought they were from something rubbing on the radiator. After quite a bit of research on modern aluminum radiator production I found out they are actually small spots of the anti-corrosion coming off/dissolving while doing its job.
I was already sending off my OE oil cooler to Pacific Oil Cooler to have it cleaned and tested after sitting for a few months. I called them and asked what they could do for my radiator and found out they could do the same for my radiator as well as Iridite coat it. I am not affiliated with Pacific Oil Cooler but I will tell you they are best known for cleaning and refurbing aircraft oil coolers to FAA standards.
More to come.
