This product is alot cheaper then the oem radiator, I feel if I can get 3 years out of it. id be content. wanted to get rid of the plastic junk. quality is actually pretty decent, Im a welder for trade and they aren't horrible. Box cam damaged but no damage to rad. So far 2 weeks no leaks. * update March 4 she started leaking I'd like a replacement if possible.

Does not come with trans line inlet or outlet fittings. Took from old radiator. Internal trans cooler has smaller holes than stock OEM. Trans temps have increased 10-20 degrees hauling in summer heat from stock radiator. May Bypass internal Trans cooler, or add dual external trans cooler. But over all no more coolant leak.

i got about 2000 miles on this radiator and its being replaced, not due to a leak or anything. its hard to see in the pictures but inside those fittings for the trans cooler, there are 2 small holes (maybe 1/8"). these holes are the only thing letting trans fluid through. i must of had some dirt or something in the system but my trans temps went from fine to overheating in 15 minutes. turns out that tiny little hole got clogged didnt flow any fluid. had to bypass this cooler for a second time and run the front trans cooler to make it home another 100 miles. look at the stock rad or another parts store brand and the holes for the trans fluid are about dime sized, lot harder to clog up. otherwise i had no other issues with this radiator, it did cool well, the oversight on the trans cooler is the reason i'm marking it at 1 star, i do not trust this thing anymore. i did try cleaning out the fittings with brake cleaner and compressed air and there is still something inside i cant get out. i'm putting mine in the recycling bin and getting a stock radiator. buy at your own risk.

Installed in my 2005 LLY. Everything fit, all lines connected perfectly and stress test after install without a single drip! The packaging was excellent quality as well. Box was damaged during shipping but every fin was still pristine. Very satisfied that I went with you guys!

Hole is so small and cuts lot of restrictions, I bypass it and run cooler in front. Other than that, nice and sturdy radiator. I would buy it again.

Installed this on my 05 LLY Dmax, didn't want to put another plastic tank radiator in my truck. This radiator was priced great and very nice quality. Thanks Erik

Size: 4 core radiator with fan and shroud
This radiator and fan combo is pretty stout on first appearance. It's been working well in my 04 gmc sierra 2500hd LB7 duramax. I tow trailers 99% of the time for my business. It hasn't overheated from the unit itself. But it's gotten a little hot from my negligence. But I'm waiting to see what happens during the summer in southwest Florida. That's the reason for a 4 and not a 5 yet. Have to male it through the summer heat in Florida first. Update- if you have been looking to change from a mechanical cooling fan to electric. These are the fans for you. Worked great through the summer. Temp in truck never got above 210°f during the summer. The only time it would get above that is my wiring would let 1 fan stop. I would fix it at my next stop. Then it would be good to go again. Other then my stupidity. I have no issues with the electric fans. Definitely recommend to anyone.
