#HONDA CIVIC POWER STEERING FLUID FULL#

I did not know at that point that they'd used a full reservoir's worth of Dex III ATF. Rather than clean the pieces out and rebuild the pumps on both Gen 2's, they purchased new pumps and I helped with the installation, system cleanup (reservoir removal and flushing) and flushing the systems repeatedly with quarts of Honda PSF. Every single seal in either pump, to include the backplate O-ring which is a captive, non-moving item, had physically degraded. I was shocked at how black the PSF was compared to mine, and theirs was newer! After draining the reservoirs, I assisted in removal of the pumps and their disassembly. A couple months later, something didn't 'feel right' in the steering, so they said to me.īeing that they did the PSF changeout based on my recommendation, I felt compelled to help them. They didn't have enough Honda PSF on hand when finished.so they shared a bottle of ATF and filled up their PS reservoirs with Dex III. Two neighbors saw me doing a PSF change on my 2003 years ago, so they did a PSF change on their Odysseys as well. Reason I know this? I've had this academic discussion before with friends of mine (and one relative) working for Exxon Mobil and a college buddy-now-materials scientist as an after-action discussion for the following event: It doesn't need to be anything better or pricier. The rubber in our PSF pump is probably the same ultra-generic nitrile makeup used in a 1980's Honda (read this as very inexpensive). They're not even close to what they used to have in them 20 years ago. It would be lousy in a recirculating ball system of any sort, whether it be one used in a steering rack, manlift, or any other application.but Dexron III can excel in these applications.Ĭurrent iterations of Dexron III have changed markedly, with compounds that will intercalate into modern synthetics used in transmission seals while remaining friendly to older spec transmission seals, and both classes of friction modifiers are now heavily halogenated. However, it's an excellent specialty fluid in this app. It does only one thing well, and that is, act as a power transmission medium in rotary vane pumps for a single motion system like a steering rack. It is the most narrowly specified hydraulic fluid I've ever seen.

The problem with with Honda PSF is that there truly is nothing magical to it, as you said. Honda PSF is still the same heavily refined, narrow fraction petroleum distillate it was in the 1990's.

Cnn, I will say in current Honda systems, do NOT do it.
