1989 Mercedes S124 230TE Ongoing Knackling

[Volksy]

Mine is showing around 300 flat cold

115 around 60c

65 at running temp of 82c

 

So mine, from the internetz advice is correct I guess! 

That's measured from the spanner flat to the pin.

Fantastic. At least I know what the issue is now. Thanks a lot!

Well I went back for the showroom experience today and collected the new sensor. The temp gauge is now functional again. Thanks for your help @Volksy.

With a spring in my step I set about fitting the clips and door trim.

Had to nick the end fixing off another door for the time being. I'll have a go at modelling a replacement for the 3D printer.

I had forgotten how much that bugged me and it all just came flooding back

The temperature sensor? I'm used to diesel's which are generally quite difficult to cook. With this having had OMGHGF in the past the lack of gauge was a bit unnerving. It actually seemed to run surprisingly cool when driving around. I had to leave it to idle for a while before it got up to that temperature.

The expansion tank is cracked. Presumably from over pressurising in the past. I'm not sure whether the fact that the system isn't really pressurised is affecting the running temps?

Soon find out. There's a second hand one winging it's way to me via Evri.

The temp guage was fine for me - or appeared to be - until it cooked.  I meant the door trim!

You might have a stuck thermostat, mine did when I got it - along with a weeping waterpump - so I replaced the lot. 

Mine gets up to 82° and will stay there all day. It only has an engine driven cooling fan.

Ta-da!

Oil pressure seems improved after a change, sitting at 2 bar at 80 degrees. We'll see what it's like once properly hot this week.

What a bastard that was to do though. Must have been the tightest oil filter I've ever encountered!

New (to me) expansion tank fitted today too.
