No PAS fluid in the reservior

Interesting vid, it's not a o ring problem unfortunately. It's definitely the line (no 16 in the diagram). Not sure what the connection on the other end is like. Most of them seem to be push fit on the diagram but no 16 looks like it is going into the rack so what the connection is like is unknown. Could always get under the car and see but I was hoping someone on the forum had done this job before. That pipe's going to corrode given that it stick out into the bumper. Hoping mine wasn't the first on the forum.

Looks a PITA to do given that the pipe goes from the front of the engine bay to the back and has numerous bolts along the way

As a temporary fix, using some petrol hose will be fine though. I have a similar lash up on my 4th gen atm as a temporary solution.

It's the same pipe (minor differences in the run between 4th/5th gen but basically all the same).
I just cut the metal pipe where it's good metal, slipped petrol hose over and jubilee clipped it. Sorted.

Cunifer home made would be the cheapest long term fix.

Never tried anything with Cunifer pipe (without googling it I couldn't tell you what it is) but I might try cutting out the rusted part and putting on some petrol hose and see if it holds pressure.

I've looked in the engine bay and some of the bolts may be rusted etc, its always the way. The pipe runs under one of the engine mounts as well. Don't know how flexible the pipe will be so getting it in and out of the bay may be tricky.

Satan's got more patience than me at times

Copper/Nickel alloy pipe.
Strong and corrosion resistant, but you can bend it about to whatever shape you like.

You buy it on rolls like this:

That hose is the low pressure return, it will be fine. There is already a section of hose on that pipe, to connect it to the reservoir.

The original pipe is steel and not flexible.
I expect if you're doing a complete replacement with original, then the engine mount will need to come out (from what I remember from being leant under the bonnet of Sam's 5th at Mimms in the middle of a monsoon, that's one of the differences in the routing between 4th/5th gen - 4th is longer and goes over the top of the mount, 5th is shorter and runs under the mount).

I've left the original pipe in place and cable tied the new hose alongside it, so that means it's kept in place, doesn't chaffe on anything or flap around.

I did take some pics of the repair I did but haven't posted them up yet

Here's one though, where I cut the pipe just behind the reservoir and joined the new hose onto it

Mine didn't need to be cut back anything like that far, but I just chose a nice easy spot to be able to cut it and fit the new hose/clip.

That would make a good signature

Now fixed

I hope

In the end I just chopped out the part that was rotten and replaced with fuel line. I drove the car into work so I'll have a look at it all when works finished to see if everything is holding up ok.

Fingers crossed.............................

I discovered a leak on the PAS cooler behind the 5 th gen front bumper.
Is it ok to remove the cooler and loop the pipes with high presure hose?
I assume the PAS cooler isn't essential in our climate?

That is what I have done. The part that was leaking was the bit that sits in the front bumper. I cut the pipes just before they turn right. I'll see if I can get a photo up tonight and confirm that it is not leaking any more.

Looks familiar.

Your leaks all fully sorted now then?

I just replaced my PAS reservoir hose clamps with jubilee clips as it was still leaking. Tested that and found it was STILL leaking!!

I found the source of mine is actually a few cracks in the PAS reservoir, where the mounting bracket is. It's leaking out the back of the reservoir and also letting air into the system, causing so much pressure that PAS fluid is being pushed past the jubilee clips on the hoses!! If they were any tighter they would be cracking the reservoir outlets...

Sourced a new one from JapanCars.ru for £20 or £30. Still cannot understand why Honda charge £130 for these in the UK.
