E200 overheating

[johnnyboy1234]

I,ve read most of the posts here regarding this issue and I,m getting most confused. So I,d be grateful if anybody can help me. How exactly do I test the viscous fan is working properly. If the fan stops when the engine is running, does that mean it,s broken, or is that what it,s supposed to do?

It,s a 1994 E200 W124 130k miles, no air conditioning, and like most of threads here, the temperature rises to the next mark after the 80 mark in heavy traffic, and goes back to the 80 mark when cool air is hitting the fan at higher speeds. Even as low 30mph will bring temp gauge back down. Can somebody explain exactl;y how to do the carrot test, and finally if it is the viscous fan problem, are there any diagrams / photos available to show how to change it.

Another thing is the heating system will not blow cold air out only hot all the time, been like that since I got it 2 years ago.

Ah the Carrot test. Ok so run the engine till its hot, very hot. Take one carrot and place it in the fan, holding on to one end, preferably the end not in the fan. If the fan dices the carrot then the viscous coupling to the fan is ok, if the fan stops then time to change to a new one (easy swap BTW). As for the heating, sounds like your duo valves are stuck. Do a search for duo valves as a member wrote a how to repair on them. Personally I would obtain a new set as the how to repair is hit and miss.

thanks for that Ian, now I understand exactly. Any idea if there are any diagrams to show me how swap them? I,m mechanically competent but my lack of self confidence in doing things new means I prefer to be handheld through the process. lol.

Excuse me from comming in, the 124 021 car shows that it uses a solinoid fan.

Please take a look at the fan belt and see if it goes around the fan pulley.if it does then you could just have a sensor fault

It does not matter either way to me as I will send you the work sheet when we know what you have

That's a 200E (M102) OP's car is an E200 with a M111 in it, no solinoid fan.

I am looking at a 124019 that is in my books an 200E and I also have a 124021 also a 200E. There are not any 124 starting with E in WIS

If the OP cares to put up the VIN first 6 numbers I will send him the correct instructions

124019 has a M111 engine, not a M102.

OP's car is a '94, all the four cylinder 124 were M111s by late 1992.

124021 is the early model with the M102 engine.

The post facelift cars all became Exxx rather than xxxE.

Big nut on the back of it, you'll need a big spanner and some brute force.

Some just use a hammer and a long chisel, but that can go horribly wrong if you're not careful.

I assume OP means me lol. Malcolm if you tell me where to get that number I,ll do it, but I remember getting shocks fitted from a FAstfit place and they sent shocks for a 200E and they were wrong. THe guy had to argue with the supplier that he sent the wrong ones. Whats the difference anyway?

Different cars.

Yours has a viscous fan, the 200E (generally) had an electromagnetic fan clutch.

They use two different engines, one the 102 and the other the 111.

On your log book for the car, the VIN number is shown starting with WDB124 and I want the next 3 numbers

They will be019 or 021

Are they on the engine or body. I,m in Ireland Malcolm, we don,t use such crude instruments as logbooks, we have vehicle registration tax documents, that are only good for the Revenue commissioners. There,d be no good reason for giving us mere mortals access to information that might be of any use to us (says he similing wryly). But seriously Malcolm all we get here is the chassis number on our legal documents.

And thanks for the quick repsonse from you both.

The chassis number is the one if it starts with WDB124

On your slam panel, or failing that on the bulkhead.

Hang on, the chassis number is all you need.

 

[grober]

the chassis number is on the VIN plate A on the front slam panel (i.e. the pressing that stretches across the front of the car on which the bonnet rests when shut and the secondary bulkhead B. It may also be on the nearside (RHD car) at the base of the windscreen C -you can read it from the outside thro the screen.
sorry Nick I see you posted this already.

Its the later twin cam engine with the viscous fan ( caution the big coupling nut has a left hand thread)

Ok thank you and I will print off the papers and post back in a bit

Can you please put up an Email address for a few mins, you can go to edit and remove it in a couple on mins
