    • 2012 Suburban without EOC perfect fit
Installed in April. Perfect fit and as others said take rubber fittings from old one. Took it on first road trip about 300 miles one way with many mountain ups and downs. Worked fine and engine temp middle all the way. Transmission temp is about 10-15 higher than stock radiator as several have mentioned. Weather is 90's also, hot summer. That is why 4 stars only. Otherwise, no leaks till now, coolant level same as day of installation. ... show more

    • Nice Radiator
I bought this radiator as a replacement for my 28" radiator so that I could convert my truck from a clutch fan to electric fans. This radiator works just right. Keeps the engine temperature right at where it should be.

I'm not sure if this is a rebuild or re-man radiator, but it was clean, doesn't leak and keep the engine cool. A good and affordable solution for folks hanging on to their old rides. Hot spotting the top of your modern V-8 may be the one thing that will most likely lead to a cascade of expensive failures. ... show more
