Review on 🌡️ Denso 221-3120 Radiator: Efficient Cooling for Optimal Engine Performance by Mario Beaklini

Revain sent me the wrong radiator (part number 221-3102) the first time, so my car sat on the ramp for a week. When the correct part arrived, I was able to install it with no problems. This is an OEM part for the IS300 and I've had no problems. Be sure to remove the cooling fan switch sensor from the old radiator near the lower radiator hose on the passenger side. I threw away my old heatsink with it and had to order a Beck Arnley 201-1801 Engine Cooling Fan Switch. I blame Revain for sending me the wrong radiator the first time. As for the cooler itself, I have no complaints. Perfect fit, good price.
