Great product.
Radiator looks great. Fit in my jeep perfectly. I did need to clock the passenger fan to miss the bolts for the old clutch fan, that was super easy.

Perfect Replacement; Fans are awesome
Bought for a ‘89 Cherokee build. Fans are fantastic and function as needed. If you’re outside the year window like myself, you will have to cut some needed space for the filler next and cap to clear. If you can replace a radiator, you can handle it.. 10/10 for my LS swap project

Missing parts
Radiator looks decent, fans look decent...The kit comes with one relay, one relay harness...a random fuse block and some basic connectors...The fans are all wired for plugs and/or a harness that isnt included. Ill have to build that myself apparently.Kit isnt complete at all.

As ordered will need to be wired in
Rad works great and as ordered. Came in undamaged and all the fittings and hose sizes were direct replacements from original only thing for anyone not experienced ordering this kit beware you will need to make connectors or splice into the fans in order to wire them to a switch or the original harness. Overall very happy with my purchase.

The fans aren’t as cool as they might seem.
Install was easy and the radiator is great quality and build. But, the fans suck. I had to remove the factory mechanical fan which I knew I’d have to but the studs were too long and hit the fan. I had to cut them to make it fit. And after all of that, the passenger side fan fell apart causing it to stop working, and the driver side spun the opposite way, I checked my wiring and it was all color correct so it is something inside the fan. That fan blowing backwards caused the transmission fluid to not properly cool, causing it to overheat and foam out of the seals in my transmission. Since then I have removed the fans, went back to the mechanical fan and oem electric fan which moves a lot more air, and will be adding an auxiliary transmission cooler. The fans are the weak point. The radiator is great itself. I’d recommend buying just a radiator and save yourself the trouble. I swapped all the fans today and it runs 20 degrees cooler and the transmission fluid hasn’t given me issues yet.

Dissatisfied
2 of the fans quit working within 2 weeks of installation. Customer service is horrible trying to get warranty or replacement information. Very dissatisfied.

Just as ordered!
Pulled the old one out and put this one in and it fit perfectly! Only took me an hour and I was ready to roll!

No where near a direct fit for me.
Took more drilling and had to remove my stock ac out to make it fit. So far seems fairly solid the little wires you get are junk I just ran mine with 10gage to a switch in the dash.
