Engine radiator Denso or KOYORAD

My all aluminum Koyorad radiator is a far superior unit than the factory original.

I'd stick with a new Denso if you want to replace yours.

I run the Koyorad 38mm radiator on my NB, with just regular Prestone green concentrate and distilled water 50/50, and OEM Mazda cap and thermostat. Coolant temps stay in the 190's at all times. It very rarely gets above 200 except on the hottest summer days, usually when sitting in traffic.

i used a denso radiator on a benz gle43. Worked out pretty well. I mean they are an oem supplier for many manufacturers.

Denso and other OEM for me. When insurance wanted to throw Napa parts at my radiator replacement destroyed by a napping squirrel in the fan assy, I ponied up the difference to go with the Denso and mechanic confirmed it was a solid choice.

Aisin water pump, Mitsuboshi or Bando belts, and replace the radiator as a preventative measure with a Denso unit.

I placed the thicker koyorad in there and fixed a lot of issues, together with hood vents helped me getting my drift car cool.

I replaced mine at 129k miles due to a small leak in the bottom of the radiator. I purchased an OEM Denso one on Amazon for 220 and it's been working great, no issues with trans temp as well.

I have the koyorad myself, bought it used. Spend some time sealing the nose to force all air through the radiator and you'll never have an overheating issue naturally aspirated.

When I ordered a koyorad I didn’t get this in the box. I sent back what I got from them it was all dented and didn’t fit.
