Coolant issue
So I finally got the LS on the road this past weekend. Everything was good until Sunday. I took it to the car wash and drove around a little in like 95 degree weather and once I parked it I noticed coolant was leaking out of the over flow tank by something that looked like a sensor. Once it cooled off and I drove it again everything was fine, until Monday. When the car is cold the overflow tank is empty but once you drive it around coolant comes into the tank and is boiling. The temperature is always at the middle. Any suggestions on what this can be? Thermostat? Fan? Blockage of some kind?

I could take a pic tom. Well the drive was maybe 30 mins. I think I'm going to change the thermostat see if that works. Do I pour coolant into the radiator or overflow tank?

I wasn't able to take any pics but I got this one off the internet. Coolant leaks out of the circled cap while the coolant in the tank boils. Any ideas?

If it is leaking out there it has to be the o ring as suggested above, the system is not pressurizing due to the O ring not sealing the system and the water is therefore boiling,pressurization raises the boiling point of the coolant.
Replace the seal and you should be OK
Lexus part # 90099-14129 $3.13
Spend the $3.13 now as if left you may damage the engine through overheating.

Upon closer inspection and the use of a flashlight, I found a small crack in the plastic near the sensor. I'm going to put epoxy as a temp. fix while I look for another reservoir.

Sorry to resurrect but is there a generic o-ring that can be used? Or could someone supply the dimensions of the real o-ring.
Unless someone can point me to one on ebay but can't seem to find a genuine one.
Lexus dealer is 2 hours away and they wont let Toyota order it even though the part number is good in there system
