Strange noise when turning the wheel in the morning...Power Steering Fluid Level

[mouratos1a]

Hi all,
I am experiencing some strange noise when turning the wheel in the morning which disppears after running a few Kms. I want to check the power steering fluid level.
Which is the right condition to do that, in the morning before the first startup or after running a few kms?
Thank you

If it was a squealing noise, it will be the serpentine belt slipping, you check the fluid cold on the steering,if it is a hot reading then it will be marked on the stick in temp, 41 in the link

Had this on a 190 recently, it turned out to be the damper on the belt tensioner being very tired.

i agree with wireman and malcolm, you could also as a quick fix spray the belt with wd 40, it is just as good as belt lube,this revitalises and softens the surface of the splined side of the belt which age hardens becomming shiny and slippy. herbiemercman.

the Hydraulic fluid tank for steering was empty...
filled it up and all is ok now...
there is a leak at the pipe connected to the fluid tank...
Thanks for the posts...

An easy fix then, thats good :-D

I would not be suprised at WD40 making your polyvee belt a bit more soft, WD40 is mostly mineral oil and will attack and quickly destroy the rubber compounds of your belt, in the interim period there would be some increase in the stickyness of the belt but what you need is grip not stick, its a different kind of friction when things are moving.

WD40 great for shifting water, lousy for anything else.

The only place for a tired belt is in the boot as an emergency spare, the engine should have a nice new one if you suspect anything untowards about it.
If it fails on the motorway (like it did to my brother in law) the cost is disproportionate to what a nice new belt costs, £420 for one tow, one belt and alternative transport to destination.

Very true and the belt should be examined for hair line cracks. One should remember when you have a squealing
belt, it gets very hot and this glazes the rubber adding to the aging.

I would second the comment re WD40 being bad for belts.

Try to keep it away from any moving or pressure rubber. People (well farmers) have a habit of spraying it on hydrolic rams to keep them lubricated - it just accelerates the wear of the oil seal, usually ending in catastrophic failure.

It is however a good get you home if your belt is slipping so bad your steering is badly affected - or the braking, as was mine on a TD isuzu
