06 RX330 running hot
Today my radiator cooling fan came on for the first time ever. A while later my temp needle moved toward hot. After stopping and let it cool some, I poured some water into the cooler reserve tank and the engined sucked about half of it in. Would it be that radiator was low on antifreeze? I have noticed no pinholes on hoses, steam or coolant leaks on driveway. After driving some more, I noticed it better but on stop lights the needle will still move some. Suggestions on what this might be are appreciated!

I'd start by replacing the thermostat and go from there.
Take a close look under the t-stat housing if the coolant plate is leaking as well.
Pressure testing the cooling system is also a way of finding small leaks.
Pink crust is also a sign of leak.
At least we know your fans are working.
How many by the way are turning ON when it gets HOT?
