2008 RX350 210k miles. Friends car. Has the common reservoir return hose leak. I think Lexus only sell the entire rubber+metal hose segment for over $100 ( PN 444060E020 link )

Anyone know alternative for just the rubber hose section on the reservoir return exit?

Hose makes a couple of turns so not sure can just use common stock hose (if so, any one know the ID?). Furthermore, auto parts store often just mix up vacuum/oil hose. Vacuum hose will collapse with heated oil in my prior experience.

 

Rock auto has one for $30 plus shipping.

THe brand is susong. I had to replace mine 5 or 6 years ago-maybe more. It's been a good part.

 

Thanks, looks like 2 different parts available. One has the hose on the other end.

Similar available on Amazon ( ) from A-Premium brand. Amazon also has Sunsong branded ones. Probably all from the same manufacturer.

Thanks

 

Was able to fix the reservoir leak without replacing the hose. Just pull out slightly to get fresh rubber on the bump on the fitting. Move clamp over this bump and added a 2nd clamp (probably not doing anything to help seal) 1 month / 500 miles later no leak.

Also previously exchanged 600mL of PS fluid with synth Dex3 ATF + a little Lucas leak stop and seems to have stopped the prior leak. Still full at max hot like before at 1mo 500 mile follow up.
