Rated 5 out of 5 by from Works Awesome This is the first review I have written for a product on CJ Pony Parts. The radiator installed easily and with no modification. It is a little thicker than the stock radiator. I have a 289 with a fan clutch and there was about a half inch of clearance once everything was installed. I had cooling problems with my car but this fixed it. Highly recommend.

Rated 5 out of 5 by from improved engine cooling Living in FL, and having to drive in rush hour traffic at times, was a challenge for the original radiator in my '66. A hole the old one prompted the switch. This new aluminum radiator looks great and my temp gauge needle appears to peg at the thermostat setting even in traffic. I bough brass plug fittings for the transmission cooling ports just because it looked more finished.

Rated 5 out of 5 by from good radiator I bought this radiator a month ago and it is a good buy. I had to drill the installation holes slightly more to get it to fit but otherwise no problem. I have ran it in the Arizona summer heat and temp gauge is a little over mid range compared to stock radiator where it was pretty much red line!

Rated 2 out of 5 by from Don't bother. Get the Scott Drake 2 core This rad does not cool any better than the original and is very thick. Too thick to get anything larger than a 14" thermo fan in. Also the cap that came with this did not hold any pressure and leaked all the time. Don't waste your time or money.

Rated 5 out of 5 by from Radiator I accidentally destroyed my old aluminum radiator. I checked several sights, but CJ pony parts had the best price plus I upgraded to a three core that looks twice as good as my old one.

Rated 5 out of 5 by from Ideal for better performance and looks Perfect fit for normal flow. I dropped a 302 stroker with this 3 core and no shrowd cover and keeps the car cool in California weather. I'll have to wait until peak summer hits but I don't expect it to over heat with the 3 core.

Rated 4 out of 5 by from nice radiator ...BUT I installed the radiator and had the same problem another reviewer had...thicker radiator so had to get another fan spacer and smaller pulley as the transmission cooler lines rubbed against it from having to reroute them.

I have this radiator and my 65 still is a challenge on a really hot day. What electric fan will mount to this radiator?

Asked by: DEPONY
P/N: FAN9 would be a good option but you would want P/N: EFR2 relay to wire it up. P/N: FAN41 is an option that does not require additional wiring.
