coolant discoloration

DANIEL TINDER (11/27/2024)

BTW: I LOVE the transparent coolant filter assembly I installed. Nice to visualize the color & flow. Not concours orig., but a worthwhile upgrade (IMO). No debris to speak of accumulated on the screen as yet, so new alum. radiator is likely well protected.

BTW: Some recent discussion on the ‘Vintage’ forum re: interaction of aluminum radiators & iron blocks has me wondering. Possibly, more frequent coolant changes (even using propylene) are likely indicated (?). How well do the alum. rads. hold up over time, (considering the ‘dissimilar metals’ issue) ?

It will be a different color from typical green antifreeze. Joe-JDC. JDC
