I'm getting ready to replace the power steering lines and reservoir on the 86.5. I have searched and only came up with advise for MY 87 forward. Not sure if the procedure is the same so I figured I would ask. Does anyone know of a step by step for 85 - 86.5 link? Any help would be great.
Thank you JD

Dwayne has generally the best write ups on S4s with lots of pics, but the PS system is pretty much the same as your car and the link takes you to a write up for the procedure you are asking for. I tried (and wasted money on ) and could not find a hose re-builder that could match the tolerances (angles) for the attachments to the rack for the hoses to/from the resv, so my advice is to bite the bullet and pay for Porsche hoses from our vendors here.

Good luck.

 

I am working from hazy recollection here, but I think it is all pretty straightforward except getting the hp line on the pump requires dropping the alternator. There is very little space around the pump. IIRC there are two clips securing the hose along its length. Sorry, I can't be more help, but it was all painless except getting the hp line on the pump.

 

Thank you to both of you. I have purchased the hoses from 928srus. I will take a look at Dwaynes write up again too.

 

For extra insurance, some of us have been fire-sleeving the high pressure hoses so that in the event of a failure, the flammable fluid under high pressure doesn't spray all over the engine bay. Run the sleeving down low and leave the bottom open. It also helps to protect the hose from the exhaust and engine heat so it should last longer.

What is the material you are using for this sleeve? Fire retardant I would assume, nomex or something?

 

It's a product made by the DEI company and their name for it is fire-sleeve. It's available in different diameters from Amazon. It's a silicone type outside with fiberglass internals so it keeps the heat away from the hose inside. Each kit comes with tape to seal the ends, but if you seal both the top and bottom and have a leak, you'll still have a bursting scenario so you seal the top and run the sleeve down past the junction between the rubber hose and metal line so that if a leak develops, it remains contained, the top stays sealed, and leaking PS fluid would be forced out the bottom of the sleeve.


In this photo you can see the open bottom of the firesleeve hose



Here you can make it out along the driver's side cam tower with the protective rubber grommet reinstalled outside the sleeving on the metal collar of the hose underneath
