Hi everyone!

The power steering cooling pipe on my 98 Terzo is looking a bit like a rusty sieve and I was looking at replacing it.

However, I have read that this may be a defunct item surplus to requirement and can simple be removed?

Has anyone done this?

Is it as simple as removing the metal pipework and associated hoses and replacing with a new flexi type samco pipe around the induction pipe?

Thanks in advance

 

Its there too help cool the hot power steering fluid, a samco hose would pop off with the huge pressure from the pump, just ask one of the breakers on here to send you out one, doubt it will be much second hand.

 

It's doing nothing in reality, probably soaking more heat in to the fluid from the radiator/engine bay when sitting in traffic. Not all Impreza's had them, so it'll be fine without. Just use suitable hose and clamps if you decide to bin it. I'm binning mine for the same reason as you and we aren't the first to do away with it.

 

Thought so, thanks.

Any idea what diameter the pipe is?

 

Sorry mate, not off the top of my head and the car is tucked away, away from home.

 

As has been said you can probably bin it without any issues.

However be VERY careful with fitting things in it's place. You need hose that is ok to use with power steering fluid. You also need a hose and fittings that can take the pressure. Luckily it's on the return side which is much lower pressure. You wouldn't want to go messing with the high pressure supply side as almost any fitting not designed for power steering would blow off spraying fluid everywhere and potentially causing a accident due to sudden heavy steering and a fire in your bay potentially writing off the car.

Just worth knowing as most people don't know that the power steering system uses very high pressure and that the fluid can cause fires.

 

I'm doing mine today, got a whole new pump to fit. I was going to delete the cooler and fit a braided hose... but if they pop off as others have mentioned I probably wont bother.

 

As FMJ says, to be honest, I can't imagine that the "return side" pipe has much pressure as mine is in such poor, rusted condition that if under any pressure it would probably spring a leak! :-)

I'll look in to pipe work type and would think a good solid jubilee clip should suffice as a fixing?

Thanks for the advice.

 

This is the hose I'm using with some finishers: http://www.ebay.co.uk/itm/1603967718...%3AMEBIDX%3AIT

Ok to use with power steering fluid according to the spec

 

how did it go with this hose CutMasterT?

 

I was hoping the hose and finishers would have arrived today but they are arriving tomorrow so haven't been able to do today. I'll update tomorrow with pics

 

Yeah guys just to clarify it's the supply side that needs proper high pressure fittings. That's why it's in one piece with a proper screw in fitting on the rack and a banjo on the pump. All my warnings refer to this.

The return side is still under pressure but far lower, as Subaru use fairly standard hose fittings for this hose on the cooler and tank it's safe to assume the same sort of fittings aftermarket will be fine.

When using braided hose make sure it doesn't touch anything. It works like a file with engine vibrations and cuts through things! If it touches anywhere either wrap that part with tape. Or before doing it up slide a nice clear piece of heat shrink tubing over the braided hose down to the area and heat it to create an invisible rubber cover for that part.

 

Done it today here's some pics.

You def need to cover up any parts of braided hoses that could be touching others, works like small file with engine vibrations. I used some cheap engine dress up tube to cover any parts that could touch anything.

Its an easy job, and looks good too

 

Great stuff, thanks for the pictures.

Keep us informed of any issues/problems that may crop-up.

Thanks.

 

Do Subaru actually list the hose to delete the cooler pipe
