Engine radiator Denso or KOYORAD

Denso is the OE for most Honda rads. I've always used them and they're good.

Denso and Koyorad are good brands.

I also replaced the radiator (I went Denso, not oem). It\u2019s gxor-ish recommended preventative maintenance every 100k.

I spent two years (off and on, as it only overheated when idling in 90+ degree conditions or when doing low-speed jeep trail climbing in the heat) chasing this on my rig. Over time, replaced fluid, thermostat, radiator cap, clutch fan. No joy. Finally pulled the radiator, and the front fins were horribly blocked. Replaced with a new Denso, and problem solved. Only issue with the new Denso was that the mounting rails on the new radiator were shite, but it was a matter of four bolts to swap over the old rails (with upper shroud still attached) to the new radiator.

I put mine in about 6 months ago. Been great!

Koyo forever! I've run them on both my is300s and my jz swapped s13

Koyorad makes a good radiator, a little expensive but worth it

Super happy with my koyorad. I bought the manual version and kept my trans cooler from when I bypassed the stock one.

I've had a koyorad in mine for almost 4 years now, zero issues. Granted I've got a manual so the only thing running through mine is coolant.

I personally I have used a Denso radiator for my Mazda protege and it been working fine for almost 30,000 miles
