no, it’s not a leak issue. The problem is do to the fan not kicking on when the car is sitting. Once it reaches operating temp. It should kit on. Check your fan fuse, or your fan relay. If there is no fan on while sitting it will overheat

It seems a problem of air flow. Start by visually examining for air blockage. You can use compressed air over the radiator or water. [Do not use high pressure washer as it will bend the fins].
Then check the connector at the bottom of the radiator. Get the circuit diagram and confirm that you can short the terminals of the connector to see if the fan kicks in. [There is a thermal switch at the bottom of the radiator. I would like you to make sure it is safe ... both keep your hand/fingers out of the way, and electrically safe to jump the terminals].

So I'm narrowing it down and I went to AutoZone for a temp switch. The one they gave me is not like the one I pulled out. The one they gave is thin and has smaller thread. The tech manual I found online calls it water temp switch no. 1. The dealership says it's no. 2. It's at the bottom of the radiator on the passenger side. Lexus wants $120. Any ideas on a cheaper option?

Please check the online parts site ... such as Lexus of south atlanta. There is temperature sensor near the top of the engine and a switch at the bottom of the radiator.
Before you buy the part, follow instruction on how to test it. You can always throw a part.
