Ls400 Power Steering Reservoir Removal Tutorial

Recommended Posts

Hi,

I've got the usual weep all over the pump (and probably alternator!), but can find anywhere on the forum how to remove the reservoir to change the little seal everyone keeps talking about. Lexus Bristol quoted me £106.25 including vat, which seems like a resonable price to do anything at Lexus!

Before I go there, maybe someone could post a link to show me how easy/hard it actually is. I've cleaned the power steering filter, which was filthy, but it hasn't slowed the leak.

I've stopped using the car to try to prevent the alternator dying, but my wife diesel Focus isn't qiute the same experince - help!

I found that there was no leak at the reservoir after I was well into dismantling it. My Fluid loss was at the p/s piston end. The Fluid damage to the alternator must have been done by pouring fluid all over the place as it is tricky filling it without a funnel.

Well would you mind telling me how to get the reservoir off anyway,

Much appreciated

Hi,

There are 3 bolts securing the reservoir to the pump.

One is accessed through the power steering pump pulley ( look through the holes and move the pulley slightly as required.

The other 2 are on the side of the pump.

The reservoir then lifts off.

Before removing the reservoir use a turkey baster ( Wilkinsons Stores £1.49) to remove as much PS fluid as possible then put plenty of rags between the PS pump and the alternator below to catch any left in the reservoir.

The "O" ring part # is 90080-30040.

Below are some photos to assist

Only the bolt at the back is almost impossible to turn without an special angled spanner and it turns about 1mm at a time!

I didn't realise that as I bought a spare one and rebuilt it just in case so the bolts were easy with it being off the car.

You can get angled ratchet spanners fairly cheap now days if this would work

All done, took about an hour and a half, nut at back was a real slow job, especially difficult to put back without dropping it! Not for the beginner, but do-able with a good selection of tools. Pleased to say leak has stopped, and alternator is still working - touch wood.

Lexus in Bristol quoted me £98 including vat and oils to do this, which is a reduced rate for owners of "old Lexus' - to stop people getting their Lexus fixed by other garages " Well woth investigating.

I tried the power steering fliud flush, found elsewhere on the site, which involves 'blipping' the engine with the key whilst a hose from the return pipe sends old fluid into a bucket, and my engine hated it. Started spinning uncontrollably even with the key in the off position, so be I must say I can't recommend this procedure, it scared the life out of me!!. If you need to change the fluid, which we all probably do, do it properly.

Easy job except for the rear bolt!!!

It was at section 5 on this page http://www.lexls.com/tutorials/steering/psflush.html that the problem occured. "immediately shut off the engine" after 3 or 4 goes, resulted in the engine running after the key had been turned off, and draining all the fluid out of the reservoir, filling the system with air. Proceed with caution.
