  • Good radiator for the price!
I installed this radiator in my 05 Dodge 5.9. It fit properly and cools well also. I've been running it for a couple years and have had no problems other than the drain petcock drips where it threads into the radiator. I didn't think to seal it before installing so that's on me. Keep that in mind. Even then it only drips when it's cold until the motor warms up then quits, so I haven't bothered with it. I'd buy it again. ... show more

  • Cheap quality radiator
This radiator lasted less than a year. And it's from the lake that cannot be fixed.

  • Perfect fitment, quality replacement, overflow barb is incorrect size.
I'll be adding coolant to the system tomorrow, however, upon unboxing, the rad seems to be a quality component. Welds seem to be proper (I filled the rad with water prior to install for a leak check, but we'll see what happens after some heat cycles & actual antifreeze is used). Perfect mounting fitment & it's noticably thinner that the alumi-plastic OE rad. Only negative is that the barb for coolant overflow isn't the same size as OE. Rad arrived in good condition; not bent as some other reviews have mentioned. ... show more

  • Great Radiator
I have been using this for around 6 months, it has been working great! It keeps the coolant temp lower during summer here in Arizona.

  • Don’t buy
Give this product a zero star review. Purchased about a year ago And had issues since it was installed. Don’t fit in rubbers radiator sticks up alittle. Not a big deal. The big deal is welds cracked. Leaked from tank to fins. Should have put the money towards a name brand radiator rather than this junk. If your the company looking at this review. Fix your welding issue. Find a new welder or something. ... show more

  • Leaking.
I have about 3000 miles on this and it is leaking. I asked about warrenty and they said it was over two years old. I get time but it’s still new. I’ll pass
