## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect replacement
*by T***N on June 6, 2024*

Great fit, great price, slid right into the car with no headaches. Would buy again (but hopefully not for this car!)

### ⭐⭐⭐⭐⭐ 2008 Subaru Forester
*by J***N on January 30, 2024*

Fits perfectly in my 2008 Forester. Easy install. Very happy.

### ⭐⭐⭐⭐⭐ Seems like a good quality radiator
*by M***. on March 6, 2022*

I am very happy with this radiator. It shipped quickly, was packaged well, and arrived early. The early arrival helped a lot because it meant my car got back on the road faster. The best part was the radiator fittings fit my 2007 Subaru Forester perfectly. The fittings for the transmission cooler come out of the radiator at 90 degrees, so they fit behind the heat shield and made installation easier. Both the radiators I looked at locally had fittings that came straight out and would not fit behind the shield.
