Updates Took a ride with the blue driver OBD2. Drove on the freeway for a few miles coolant temperature stay below 187°f. Took the off ramp drove for a few more mile with moderate stop and go traffic. Temperature rise to 205°f. Still didn't hear high speed fans coming on. Once moving temps drop to 190°f. Outside temperature was 80°f I Pulled over and have the car idle, after a minute the temperature rise to 208°f and drop to 185°f when cooling fan (low) came on. High speed still did not came on. Is this normal? Any RX owners with this issues? Thanks in advance

30 minutes at most, haven't had the chance to drive much. I would say low stop and go traffic. Temperatures are in the low 90°f. I left the car idleing for 5-10 minutes still no high speed. Going to monitor coolant temperature when my scanner arrived today.

Out side temperature is high 80s to mid 90°f just got the car not long ago. I haven't a clue how Lexus cooling fan operate. Been driving a rsx type s for the past 12 years. Fingers crossed it's just not hot enough to trigger the high-speed.

A little back story, I bought the rx330 a few weeks ago with the issue of both cooling fans that run continuously on full blast as long as the car runs. Doesn't matter if AC is on or off. Found out that the issue was the cooling fan module. After replacement the fans only comes on after driving and letting it idle for awhile also with the AC running. The problem I now have is the fans would never kick into high speed it should kick in at 203°f . Car runs great its not overheating. The temperature gauge is spot on the middle. Just ordered a scanner with live data to make sure the gauge is reading correctly. I'll keep you guys updated if I find anything else. Sorry for the double post from earlier.
