Power Steering Flush and Reservoir Cleaning

*Please Read the Pinned Comment Below for some Helpful Tips.*
In this video, we show you how to perform a full flush of your power steering system followed by a thorough cleaning of the reservoir fine mesh filter screen. Power steering fluid renewal is one of those maintenance procedures people forget about and also avoid because there's not a straightforward way to accomplish it like changing your engine oil and filter.
We show you how to do the procedure on a Toyota 3.4 Liter V6 engine but the flush procedure could be used on any vehicle. The removal and reinstallation of the reservoir we show is specific to the Toyota 3.4 Liter V6 but the method we show to clean out the fine mesh filter could be used on many other vehicles.
**People have reported that the o-ring on the reservoir suction port has torn either while removing the reservoir from the pump or reinstalling the reservoir onto the pump. It would be a good idea to buy one of these o-rings in advance and replace the o-ring as part of this job. #90301-11016

*Here's the special parts we purchased for this job.*
*3/8” Hose Mender
This was used to couple the OEM return line to the 3/8” fuel injection hose that led to the 1 gallon catch-basin.

*Master Pro Hose Clamps 5/16-5/8”
Thees were used to secure the bolt to the short section of hose and then secure that hose to the return nipple on the side of the power steering reservoir.

*3/8” Fuel Injection Hose (Bulk) - I purchased 3 feet.
This was the hose used to make the return port stopper and also extend the return hose to the 1 gallon catch-basin.

*Bolt from Home Depot - 7/16” - 14 x 2-1/2” - Grade 8 Course
I cut the threads off the end of the bolt so all I had was the smooth steel shank. I filed down the edges smooth and used this as the stopper for the short section of hose that I connected to the power steering reservoir return port.

*Mitivac Fluid Extractor amzn.to/2q0m7xz
This looked like a nice tool to use for drawing fluid out from reservoirs like power steering, brake master cylinder or a supercharger nose cone so I bought it. With the turkey baster, you're limited on how deep you can get into the reservoir and you're also limited on the volume it can suck up. This extractor is 12 inches long and looks like it could draw out a lot of fluid in one shot speeding up the process to renew the fluid.
*1 Gallon Food Grade Container
This was used as the catch-basin for the flush procedure.
