That's an interesting approach for the dealer to take. When I got my 07 in the summer of 16' my power steering fluid looked like cola. I started sucking the fluid out of the reservoir about once a week and refilling with fresh. Took two quarts for it to look red after a week of driving. Now I will change it out at every oil change. Hopefully, this approach won't make my rack start leaking sooner but who knows.

We just purchased a used 2008 RX350 AWD our previous car was an RX300 AWD. I did the full transmission filter and fluid change on the old RX300 as outlined here:

-Specifically they locate the oil cooler outlet hose in the tutorial which allows you to drain a couple more quarts when you start the car (after putting new fliud in the trans), almost like a full flush with no possible damage:

I like that method as it fully drains the transmission fluid and cooler as well as unloading the magnets and freeing up flow with a new filter. Has someone identified the oil cooler outlet hose on our RX350's so I can perform the same level of fluid change on our new to us RX350?

Can anyone help me identify the oil cooler outlet line?
