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

Denso is an original brand radiator for Lexus. BUT the temperature sensor for the fans, which screws into the original heatsink, has an o-ring that seals it when installed. There is no room for an O-ring in a new radiator. The thread on the sensor does not taper, so it is leaking. After many different sealing attempts, I finally wrapped the threads with Teflon tape about 4-5 times and screwed them in. So far so good, but I've never felt so confident improvising with something like this.
