Anyone have direct experience with this? Recently bought a new cheap ebay dual core radiator with 2 12" electric fans. This has cooled the car fine up until I use the AC in stop and go traffic on hot days. Without the AC on the car will stay around 190-210* (180 thermo). Even on 100*+ days I've seen a highest reading of 210 or so. On the highway I can run the AC on hot days without any overheating issues.

Due to my hx40 install and manifold choice I have no room for a schroud. But a 24" radiator is covered decently by 2 12" fans. I know a schroud is best, exploring all my options first.

Do you think switching to a 3 row core radiator will make that much of a difference? The 3 core units I'm looking at are the same 2" thickness as my current 2 core. I can't see them cooling that much better.

-Thanks!:thumb:
