Denso 221-3604 Radiator

From my experience, Subies prefer Subaru branded or Denso components. The Denso I'm pretty sure came with the car when new. Given replacement takes 2 hrs., it's not worth saving $20 to buy an "off-brand" radiator. Fit was perfect, and it was packaged very well. I noticed one reviewer modified transmission lines to fit- all you have to do is loosen the nuts on the lines on the new radiator to match old radiator angles and re-tighten. Even though this Legacy has a MT, I've replaced other radiators on older Impreza's (05 and 07) with automatic transmissions and adjusting the lines on new radiator to match positions of old radiator solves this problem. Don't forget to replace radiator cap and hoses while you're doing this job.

Replaced the OEM Calsonic Kansei with this Denso radiator. Was a 100percent drop in replacement with the metal fittings for the power steering were already attached. One drawback for this unit is that it doesn’t include the foam at the top and bottom to create a snug fit in the car. You need to buy some foam that has a high operating temperature to handle the heat.

This Denso Radiator was a perfect fit. Exact dimensions, and locations/format of all fittings and mounting points.Product was shipped in its standard storage box, and the radiator was sliding around inside the box. After opening, I saw there were no packing materials to hold the radiator in place to protect it during shipping.Upon unboxing the radiator, it was in good shape, no damage to be found.Installed in the Forester quickly and easily.No leaks.Works perfectly!Very happy with the purchase!

Perfect for my Subie Forester. Metal transmission cooling elbow has backing washer where it mounts to radiator. Just like my original radiator. Day 2 so far so good, no leaks. This does NOT come with foam vibration strips. I salvaged the 2 foam strips from original. Double sided tape to hold them in place.

Fit was perfect, radiator works flawlessly, no problems.

There was a review with a picture of the side of a radiator someone received with a slight gap in it. If anyone is stressing about it, mine came the same way and so did the original Calsonic I was replacing. FWIW that Calsonic lasted 16 years and 164k miles before giving up. Well built!Separately, I can't help but feel like anyone who is having theirs give up prematurely is probably succumbing to electrolysis and just not monitoring their system closely enough - read: electrolysis.

It fit like it should, the transmission cooler lines are straight out on a factory radiator. On the Denso unit the are on a 90 degree turn. I cut the hoses some and was able to overcome the difference. The fans fit like they should and the mounting Tara’s all lined up. I removed the foam from the factory unit and used 3M spray glue and put the foam back as it should be. I would definitely use this radiator again.

What more can I say other than perfect fit, holds the coolest (no leaks) and does what it is suppose too!
