P80 bypass ps pump, which belt, which routing

[RickHaleParker]

You only have alternator load if you keep the AC off. But, I agree, getting a belt on tight enough to drive the alternator without slipping looks like a challenge

Remove the serpentine belt, run a length of string from the crankshaft to alternator. If the string is deflected by the Tensioner, the Tensioner will keep the short belt tight. If not, you would need to determine the length of the short belt with precision.

1. Disconnect the hoses from the PS pump to the Rack.
2. Shunt a hose from the PS out to the PS return.
3. Top the PS pump off with fluid.
4. Drive the thing home.

If one can get the two hoses off on the rack end then couple the two together that would do the trick.

Rick..next time I’m at a junkyard I will cut off a PS hose and attach and make up this return hose for an emergency. Then you can do the disconnect at the pump and not have to worry about those expensive PS lines

I think that’s the cleanest solution here.

Abscate you only need the Alternator to get home. I'm wondering if you can take one of them Emergency Adjustable V belts wrap it around just the Crankshaft and Alternator. As long as the Alternator keeps the battery up your make it home.

PS: If this would work might just as well add a pair of Pantyhoses to the Emergency Kit. Don't let the other half peek in the kit, it might be a hard sell explaining the reason.

How long will p80 run on battery alone?

You could follow with another car and swap batteries back and forth to charge them back up. Maybe.

About 30 years ago panty hose twisted and the knot burned together with the cigarette lighter is how we made it about 200kms without an alternator. We ran into two old ladies on their way back from lawn bowls who gladly gave up a pair (not from their legs, though)

When that broke we started tearing up nylon seat covers and doing the same thing. The battery went so flat in 300kms that we made it into a town called Beaufort where a mechanic welded our alternator brackets back together. Car was a 1974 Holden TA Torana with a 1600cc Dodge Colt engine and 5 speed Mitsubishi manual trans (in our market was called a Chrysler Galant)

Once you learn how to burn the knot your home and "hosed" haha

One could take a page from the Redneck A/C hack. Put a generator in the trunk, use it to power a battery charger instead of a 110V Window A/C.

Abscate, thanks for starting this thread. This is a very interesting topic.

Question to everyone: worse case scenario - if nothing is done and all fluid leaks out and no re-routing of any hoses, what would happen? Would the pump just burn up? If the rack is operated for extended periods of time with no fluid or only residual fluid, would it eventually just break apart? Could the steering completely lock up?

As I mentioned in the other post, if my rack is shot and needs full replacement, it’s likely the end of this V70. Just trying to see how long it might reasonably be driven until it fails completely.

Read that tip in the Haynes manual, no doubt.


There’s no danger to the rack, Sonic. Loss of pressure just means no assist. I’m not sure on the pump. I want to say you could make the 100 miles ok but I can’t back that with real expertise.

I have been very curious regarding this topic for a while. I think the best option would be to either loop the in/out line son the pump, or make the pulley freewheel. Another option I have wanted to explore is custom fabricating a bracket to support a pulley in place of the PS pump. If done right, would still use stock belt and stock routing. Of course, this would be a more long term solution than an emergency fix. How hard is it to pull the pulley off the PS pump?

As for safety, power steering is a luxury that benefits very low speed driving (i.e. parking). At speeds above 25mph, you should be able to palm the wheel with ease. At highway speeds, PS can actually be more of a safety hazard, as it makes it easier to throw your car into a skid (unless you're into that sort of thing).

Take the entire serpentine belt off - it isn't needed for this emergency... Pull my "red neck alternator" trick of putting a genny in the back seat with all windows open and a battery charger plugged in. ~10-15 amps @14V should do it unless headlights, brake lights, etc are on for long. Other option would be to loop power steering pump output back into suction/supply.
