NOTE: This Application Requires Notching The Rubber Tabs On Your Saddle Radiator Mounts To Make Them Square. This Is Because The Factory Tanks Are Molded Round And Champion Radiator Tanks Are Fabricated Square. This Modification Can Easily Be Performed By A Qualified Mechanic.

Just wondered if it's a good choice or go with the more expensive 2 core I saw for 530 this one's half that.

I believe that this radiator has an automatic transmission cooler mounted in the right side tank. I ordered one many years ago and was disappointed by the baffle that is very close to the coolant outlet port. I returned it for a refund.


You can see the fittings that the transmission fluid hoses would connect to on the right side tank. Of course on a ZR-1 these connections would be unused but the tube and fins heat exchanger is there in the coolant flow path.


I don't know if the cooler in the right side tank actually causes an engine coolant flow reduction, but it certainly can't make the flow better.

Go with the 2 core DeWitts.
Radiator's aren't a place you want to "cheap out"
Eckler's is always $$$!
Got mine at Summit $529, free shipping too!
Fit wasn't too bad.
Change your thermostat and hoses while you're there.

I switched to Dewitt double row and never looked back.
Minor modification to fan shroud is necessary.
