💧 Denso 221-3401 Radiator: Top-Quality Cooling System Component for Optimal Performance Review

Based on our own experience, this radiator failed to last even a few months after installation. While it was easy to install, it didn't perform well in terms of preventing overheating. The only positive is that it comes with a warranty, but we wouldn't recommend it based on our experience.

I installed this Denso radiator 221-3401 on my 2002 Maxima with 6 speed manual transmission a few months ago. Fits perfectly and has been working great ever since. You will notice that this radiator has two pipes sticking out from the bottom. They don't use them on manual Max's as they are designed to connect to automatic transmission cooling lines. Just leave them alone and plug in a new heatsink.

This radiator works great, I replaced it on my 2002 Infiniti i35 with 22x.xxx miles which appears to be has the original heatsink. Well, that keeps the car 10-20 degrees colder and ready for summer. I'm using a Bluetooth OBD device connected to an old Android phone to track a car and it's a car that's running with the AC on then idling at a traffic light. In a few moments, the car rose to 210
