Replacement O-rings for power steering pump

[aturnick54]

Suffered a power steering leak at the pump, so looking to replace the high pressure line O-ring, and the reservoir O-ring.

Not too sure where to get these from, and struggling to find a part number or anywhere selling them online. Any advice?

Be an idea to let us know make, model & year of the vehicle in question.

It's a Renault Laguna Coupe 2010, it's the 2.0dci 150 version with the hydro electric pump.

Few suggestions:

Try parts dept of local Renault franchised dealer to see if they are available & if they have a part number for them make a note of it.

Remove the O rings, measure & search online for the size. You'll also need to know what material the correct ones are made of.

Remove & take into a local bearings specialist to see if they can identify.

Ask on a Renault Laguna specific website. Chances are someone will have done the job!

Thanks for suggestions, have contacted dealer to see if they can advise. Have a feeling they will try and sell an entire pump. £280 worth of pump for a 50p gasket, mad.

Measured them. One is 12mm x 2mm which is a fairly common size. The other one is 95mm x 3.5mm which is harder to find.

Sadly it is not documented on any owners sites

How about a quick ebay search?

All you need to know is what they are made of.

Thanks for link. I'd presume nitrile is suitable given that ATF goes in the pump.

Update:

Dealer have said that the gasket is part of the pump, pump is expensive and possibly needs coding to the car so trying to avoid a new pump.
They at least do the high pressure line O-ring so have ordered that.

As for the larger gasket, now looking at using gasket maker to help seal it. Can't see any reason why this wouldn't work.
