My power steering was leaking and I was just going to replace them with rubber hoses. You could get some from somewhere that sells hydralic hoses quite cheap I imagine. If you do go for rubber make sure you sheild the hoses if they run by the exhaust or somewhere hot.
Mine turned out to be a loose jubilee clip so I didnt need to do it in the end but someone on this board replied to my thread to say that they had done it on a Calibra.
Right i'm experienced in this problem after having it myself a couple months ago.
a)The long metal pipe that runs from the reserviour to the pump - this has rubber for the last 15cm either end and is only jubilee clipped on. Don't bother with a replacement metal pipe. Use a high pressure rubber hose. This hose cost me £10. Vaux wanted £130!!! for the replacement metal pipe. Plus the rubber hose is far more flexible. To get out the old corroded pipe, break the pipe and take it out in two pieces. Trying to get it out in one piece is pointless and difficult as feck.
b)the shorter smaller diameter metal pipe - this is the pressurised pipe. It connects to to another pipe about 3 quarters of the way along the bottom of the rad. This connection is likely to seized to fook. Use a blow torch to heat up the connection and it should unscrew. Best bet for this pipe is to take the pipe to a local hydraulic/pipe place. Give them the old pipe as something to work from. Again Vaux wanted more than £100 for this. I paid £35.
Don't bother removing the radiator. Just remove the fan, this gets you plenty of access.
And, remember to fit a new washer at the pump connection of the smaller diameter, pressurised pipe.
I've too had the same problem with my Calibra C20XE.
There was nothign wrong with the PAS pipes themselves, but when I remvoed the engine they looked like thy were only going to last 5 minutes due to the amount of rust that was on them. It looked like you could squeeze them with your fingers and them would crumble!
Had another look at the PAS pipes, there are 4 PAS pipes for my car (no air con). 2 of them need replacing, the othr 2 are ok. But the 2 rusty ones are rusted to the good ones (the unions won't unbolt). So I phoned up VX dealer for prices.
90 473 966 = PAS hose & pipe, reservoir to pump (ident KB)
90 473 964 = PAS hose & pipe, assy pump to cooling pipe (ident KD)
90 344 065 = PAS cooling pipe network (ident AA)
90 425 909 = PAS hose & pipe, cooling pipe to steering gear (ident TQ)
So autovaux can save about £10 per pipe.
If I went to VX and got them, inc VAT = £369
Autovaux would be, inc VAT = £304
Still a lot of money.
So what did you do?
Nothing, I kept them. I took them off the car (took a long itme to do since they would not unbolt), rubbed them down.....and there was nothing worng with them. It was just very heavy surface rust. Inspected the pitting, no problems, rocoated it with oxide and then painted them with ally paint. Jobs a good'en.
