oem 538 on autoatlanta akg rad csf quote was over 800$

 

AKG makes the OEM radiators for Porsche. I paid just under $1500 for all 3 if I recall. My race shop used OEM radiators for years on all the race cars including those running PCA sprint races and also on those running 12hr endurance races. It's generally pretty hard to outsmart those Porsche engineers. Many choices out there, go with what gives you the warm and fuzzy at the end of the day.

 

my front/center one took a poop last year, after 12-13 years, I don't blame it.

Next time soak it a bit with wd-40 before trying to unscrew it -

 

Just put a hole in the radiator trying to get bolt out. Made that decision easy

 

I finally replaced the radiators. It was not hard at all even for a newb like me. Onto the next project
