I have a 2004 Lexus RX330 and while changing out the power steering fluid, I noticed the overflow tube for the radiator is missing in action. I looked on the Lexus site and they want $9 for a piece of rubber hose. I was thinking I could go to Lowes and get a rubber hose cut to the proper length; however, I wasn't sure what size it was at the overflow connection. Anyone know? Thanks.

 

I cannot recall the size but I bought some from Home Depot and replaced it. I zip tied it as well to make sure it drained in The right spot.
