LS 400 Power steering leak.

[shanra]

I had replaced my steering pump and reservoir with a refurbished one from the USA nearly two years ago and at my last MOT a slight leak was noticed. I had a new o ring to seal the reservoir to pump joint so I took my car to my local garage to do the job and lo and behold when I got home the leak was far worse than before, so back to the garage and they had too much work and no o ring, so I ordered another and did the job myself this morning. A few tips for doing this job, remove spark plug/distributor cover as that will give you easier access to the top bolt as that's the difficult one, use vaseline on the o ring when replacing it as this helps ease it in without hopefully damaging it (a tip from an ex mechanic) be very careful when lining up reservoir for the bolts you don't damage that delicate brand new o ring and do the bolts up gradually so as again to not damage the o ring. The rear bolt is quite fiddly to get on but patience is the key. The old o ring was torn almost in half by the mechanic at the garage not taking care when replacing the bolts and doing the bottom and side bolts up too tight before having to back them off to replace the top one. I shall not be using that garage again needless to say! One more thing I would recommend is to get your Pump refurbished in this country as then warranty claims will be a lot easier!

Perhaps naming the garage will prevent others from having problems in the future?

This is a good place for pump refurb https://www.carparts-direct.co.uk/power-steering-pumps
