Td5 PAS hose - reservoir to pump - barb fitting and gasket to suit?

[twr7cx]

It would seem that I have a power steering leak as when I checked my fluids on Sunday evening the PAS reservoir was missing 1/3rd. Traced the mess and fluid run to the bottom of the power steering pump, possibly the PAS hose that goes from the reservoir to the pump.

The reservoir side is just a standard hose slipping over a male bar with a hose clamp.
The pump side however looks to have two bolts mating it to the pump (one that is visible is circled in purple):

The replacement hose, ANR6974, however seems to not include this part, only the rubber hose part. So I assume the crimped hose clamp (circled in red) has to be removed and replaced to change the hose? The part of the hose in yellow below would slide over that hose tail and then require a clamp to secure and seal.

Are the original crimped hose clamps known to fail by loosing their tension over time or anything of the like?

Is there a gasket or anything to replace on that hose tail mounted on the bottom of the pump? I couldn't find in Microcat.

The clamps are called cobra clip you can get them of with a special tool,(I think you can flip them with a screw driver I bought the tool to remove them[smilebigeye]) they kept there tension very well and don't fail that often

The hose connections to your pump don’t look excessively oily so I am guessing that it is the ol’ metal U pipe banging on the sump trick (that our beloved mark is renowned for) causing your leak?

The Rave WS manual identifies the hose tail as a low pressure adaptor pipe and indicates that there is a replaceable O-ring under it. However, as you have found, Microcat doesn’t list a part for it. All the replacement PAS pumps I have seen come with this hose-tail already attached.

I too have a power steering leak and a similar question to yours but mine is on the high pressure side D2 Power Steering Pump Hose O-Ring? (https://www.aulro.com/afvb/discovery-2-a/271095-d2-power-steering-pump-hose-o-ring.html)

I am interested to know how many litres of PAS fluid are needed for the hose change over and bleed.

Just get a small flat head screwdriver to flip open the clamp, and fit a new "normal" hose clamp with the new hose. I actually would speculate that the pump itself is leaking between the 2 halves of the pump body. A common failure and leak point. Remedy is new pump unfortunately...

I cleaned up a trail of coolant away from the water pump weep hole (I replaced the pump in early 2015 - it hasn’t lasted that well...) so I guess it’s probably a water pump, power steering pump and bracket o-ring replacement all in one hit coming up.

I wouldnt be overly concerned,, I did 3 pumps in 6 months,, and (the last) two were really good ones! put on by Pro's... or so HE told me,,,, [bigwhistle][bighmmm][tonguewink]

OUCH! It is not only the cost of the pumps but the fluids aren't cheap either. Is it possible to change out the PAS pump while leaving the cooling system in tact (coolant pump with hoses still connected pushed out of the way)? Otherwise you're up for coolant as well. The RAVE manual doesn't mention anything about the coolant pump or the oil return pipe behind it that also looks to be in the way.

Yes, changing the PAS pump is reasonably quick and easy and does not require disturbing anything in the cooling system. Changing the water pump however requires moving the PAS pump out of the way to remove the bracket - it can be done leaving the bracket in situ but having successfully done this previously I would highly recommend against it - it's actually quicker, easier and less frustrating to remove the bracket than do in situ and you have the added bonus of changing the bracket o-ring seal too which is likely going to fail shortly if the pump has already.


Back to the original topic I went to remove my PAS pump only to find that the high pressure fitting was almost finger tight only loose. I disconnected it, replaced the o-ring and have refitted.
Turned out the water pump was also ok as I cleaned up the dried coolant train from the weep hole a fortnight ago, pressure tested the cooling system and replaced the bottom hose clamp on the top radiator hose to fix the only leak and in the past two weeks the reservoir hasn't gone down a drop and no visual evidence of coolant leaks underneath.
Looks like I just got lucky...
