Just a follow up .
Finally was able to complete radiator install on my 87 s3.
Replaced radiator with new unit from Vick, new upper and lower hoses, new clamps, new fan shroud.
Fan was in good order...not faded or brittle so I left it.
Bled out cooling system, replaced fluid, fired up....good to go!!
So far so good.
Was proud of myself for I have never replaced one before.
Thanks for all your input/guidance.
