W124 E300 Water pump

[Gazzaj]

Having collected my shining car from the body shop on saturday with its gleaming refurbished alloys, back and front bumpers, I thought thank god its finished, right up till my water pump bearings went on the way home!! How difficult is this job to do? Has anyone here done it before? are there any bits to watch out for ie siezed parts?

 

[television]

That was a shame,,I will see if I have a paper to do the job, its not too hard a job

I have heard that the impellers are plastic and can become brittle with age.

 

[Gazzaj]

What are impellers?

 

[television]

The impeller is what drives the water around, the newer replacements are now made in alli.

What is wrong with yours

 

[Gazzaj]

Bearings have gone, it was whining for the best part of of last month, now its upgraded itself to a metallic rattling

 

[television]

Are you sure that it is not the idler that sits underneath,, that it is not the idler, that sits underneath, its 99 times that

 

[Gazzaj]

Its losing water ? would the idler lose water ?

 

[television]

Its losing water ? would the idler lose water ?

OK we did not have that bit of info,, then you have got to change the pump

I will dig up some info later in the day

If I am honest with you in my opinion, these are one of the tougher merc water pumps to do.

 

[colechelle]

Gotta to agree there Ellsy, did one few weeks ago!!!

My 124 water pump went in the middle of Stockholm,,so that saved me the job of a DIY back in 1991, and that cost me all of £150 back then including picking up the car

I love your comment television "a nice little how to thread" !! Yeah its nice because he's missed out the several thousand steps I had to go through today, knees on ice, and hands caked in 21 years of crap. fails to mention the removal of the radiator, the power steering pump, the three quarter mile aux belt, the tensioner brace, and the tension shock!! and how he managed to get the fourth bolt out! I shall hunt him down!! I'm begining to regret starting this job !

I can send you the MB paper on how to do it

 

[Gazzaj]

Please do that would be great ! I have a haynes manual, which should be entitled "water pump what we think it should be like but dont really know, so we'll have a wild stab at it"

On my 124 320 coupe auto it is rated at 6 hours.

You would not want to be doing that again in a hurry so PLEASE only use a genuine Mercedes water pump.

It will last another 15 years, and only use the proper Mercedes ph neutral coolant to ensure long life in the other parts of the cooling circuit also ie. radiator, duo valves, etc etc etc.
