I've got the Fordillac's new radiators in, filled and burped. No leaks, and idling in the shop the cooling fans now cycle on, then shut down, and repeat. Never did before, they came on and stayed on, regardless of ambient temps. The new front radiator required a little trimming on the grill shell strut rod brackets, and the rear fans shrouds had to be trimmed to fit under the floor brace, but it's all tucked in. We'll find out tommorow if it runs cooler driving in summer heat. I'm pretty confident the new set up will keep the big Caddy cool. It certainly LOOKS better, way more tubes, deeper core, more capacity. We'll see! Brian http://flynbrian48.wordpress.com/
Drove it today, 85 degrees, temp never over 190, let it idle in the drive about 10 minutes after the drive, still never over 195. Success! I'm very impressed with the new radiator, it even LOOKS like Hot Rod parts!
Brian, Congrats on taming the Caddy's overheating ! Do you think you still need two radiators ? May have missed something in that part of the build thread.
