## Customer Reviews

### ⭐⭐⭐⭐⭐ Fits with 2 small modified nuts for the upper bracket
*by M***. on November 16, 2023*

I was replacing the RX8 coolant tank, and as others have experienced, the plastic pipe on the top of the radiator snapped off.Needing a replacement ASAP, I found this one on Amazon and liked the fact it was not made of plastic.While the reviews about the fit were concerning, I ordered this aluminum one and it arrived the next day.The fan shroud hole was just 1/16" off and so a round file quickly adjusted the hole in the shroud.The nuts on the top bracket were another matter.When comparing to the old radiator, the bracket centers were 1/4" different, this looked like a show stopper.Looking closely at the radiator mounting brackets on the car, they have oblong holes that allow left/right adjustment to match the new radiator (images attached)Next, the original round flange nuts would not work as another person had mentioned in their review.Fortunately, I found a simple fix. Take two of the smaller square bolts off the old plastic radiator and file off one side at an angle along with shortening the corresponding isolation studs. The modified nuts fit perfectly in the brackets. (image attached).It does require screwing in the studs from underneath once the radiator is in place.Another tip, put piece of cardboard on top of the AC condensor to prevent scratching it when sliding the radiator back in (image attached), just don't forget remove it before securing the condenserI did make two additional changes:First, I added some nylon washers for spacing when I re-attached the AC condenser to the radiatorSecond, I picked up some new foam (FrostKing 2-1/4 in. square X 42 in. Gray Air Conditioner Weatherseal Foam from Home Depot) and attached it with 3M Supper 77 Spray Adhesive to the sides and the bottom after the radiator was secured.

### ⭐⭐⭐⭐⭐ Very good quality good cooling effect over stock.
*by M***L on February 19, 2023*

The media could not be loaded. Wobble out the top 2 hanging points before installing into the car. Loosen the top hangers from underneath the var ad well. The put radiator in and bolt it down. Everything else was very easy to put together.

### ⭐⭐⭐ Seems great, but does NOT fit right
*by V***V on December 19, 2024*

the mounting bits for the top that connect it to the rubber mounting bushings do not fit. I don't know who decided this was a good idea. The stud will not clear the radiator head and a nut will NOT go on.In order to make this work you will have to modify it with a rotary tool to change the hole to a slot, or tie it down some how. Now since I've already mounted everything back up except this I'm stuck with it and I'm not sure what to do.You think for $300 they'd have this figured out. The Koyo radiator doesn't have this issue and is only a little more expensive. Would not recommend this over the Koyo at all for this one reason.
