After reading rave reviews about Koyorad on here, I decided to get one to replace the leaking unit in my I35. After installing it, I went to fill up coolant when I noticed fluid leaking out of the top seam underneath the upper rad hose. Quality control must've been asleep when they waved this radiator through because it was blatantly obvious the seam wasn't crimped enough.

So after all that work and getting coolant and ATF all over myself, I had to take out the POS unit and send it back. Bought another company's rad from Advance Auto Parts and it's working fine. Just my luck having a bad experience with a product that's supposedly great quality.

 

Story of my life.

 

Advance radiators are good. The one I got for my Z32 is Visteon.

 

Wow what A joke, they should send you fluid and pills too with A refund for that headache.
