Power steering fluid help

[Howard]

Hi all

Bought some new power steering fluid for the A class ( OEM ) ...

Anyway , it's blue and is called 'multigrade oil' part number is A001 989 24 03 10 and was £13 ish.

However , the oil in the power steering reservoir is yellow , now i know that you can't mix ATF with power steering fluid , so any ideas why this fluid that is already in there may be yellow and not blue ?

Just want to make sure before i top it up.

Thanks

I think yellow is normal. The multi grade oil is the correct oil for the power steering so cant be wrong.

we use CHF from Euro Car Parts.. Its the proper yellow/green stuff for power steering.

Thanks Jay.

This is the genuine MB approved OEM fluid , for the A class ( i can't use it in the CLK as it takes a different spec according to the chart )

Really? I though the multigrade oil is suitable for power steering all mercs from around the 202 era and upwards.

You should use 0.8 litres of hydraulic fluid meeting MB 345.0 A0019892403 such as Fuchs TITAN ZH 4300B Synthetic Hydraulic / Active Suspension / Power Steering Fluid

ref MB 345.0 - Hydraulic fluids (Specification 345.0) - Mercedes-Benz Specifications for Operating Fluids

I thought A001 989 24 03 10 was the latest auto-transmission fluid ATF 4134 meeting MB 236.14 for latest 7speed boxes???

Hmmmmm ...

I bought it from an MB dealer , and thats what their chart said to use.

You can use it in a 209 CLK for the power steering as well as the A class , but not a 208 ...

Don't know what to do now ...

I don't know what to advise you Howard? The spec I gave you is sourced from an official MB list of lubricants and from Fuchs [OEM to MERC] technical literature. Without casting aspersions did you see the list your MB parts man used? Its quite possible the latest ATF ?? is an acceptable SUBSTITUTE fluid which would explain the different colour. and crucially---------is all they had in stock! I would go for correct stuff particularly if you are topping up rather than doing a complete change but that's just me.

Further to what Grober said about the spec being 345.0 ... see also:

Its is a green oil call Pentosin.

ECP sell it.

Based on the MB specsheet, is seems that both are suitable - i.e. the MB oil you bought (which appears to be the correct one) and the Pentosin oil.

One is green the other is yellow? So the question is not whether you got the right oil from MB - looks like you did - but whether the two can be safely mixed?
