So to Everyone that has had cooling issues, I had the same! even after ALL the panels. Rubber fillers, Bottom panel. even the new clutch Fan and 160 thermostat still ran 185 at a steady 45 and 210 with the AC on.
I saw Bronze Bird put in a Champion Radiator so I figured it would work.
Wound up buying this
It is the 4 core version.
Very Nice Quality.
The original came out very easy, only issue was the lower trans line was seated FIRMLY in the radiator. After some persuasion it came out.
Here are some Pics of the Install
Original 4 core Radiator
Its Out! you can see the New A/C condenser.
Original Radiator (not throwing it away ha!) Im guessing it could be recored? didnt leak, but sure it had some repairs in the last 47 years.
All in,
Results are impressive! 165 or so cruising 175 or so with A/C on. hasnt gone above 175 yet! Sure this old engine finally likes being cool!
