So my son said car temp at gauge went to the red mark on gauge while idling, here I'm checking things and really find no issues?

My 1988 230E runs at About 85/87 degrees and runs happily at that no issues with that if it goes over 90 I'd be concerned tbh

Next time the gauge shows hot hit the top of the dash. Analogue gauge may have bad connection around display. It works on mine.

87 c is like 190 f for me to hot in the summer I’ll put it back in in the winter . These cars Iove cold wether . Someone said it would run about 55 c with out thermostat that’s about 110 f that sould be good in the summer

Mine goes over 100 in summertime, during conditions of stop &go traffic. New head gasket, new everything. Is it normal?

Ideally they should be between the 85 and 100 mark, over its hard on the engine, just keep an eye on it.

@@mygermancars7264 Thanks a lot! 100 is the next line after the 80 with no marks on it right?

Did you find the problem?

Yes, auxiliary fans high speed function did not work, only low speed worked. Climate control unit was not wired correctly.

It's at a completely normal temperature

I am going to run mine without the thermostat this summer. I gutted on I am going to bring it way down

These cars just run hot during the summer months, crazy system, I’ve replaced every part of cooling system and it still runs hot in stop and go traffic with AC on, the AUX fans high speed hack I did allows me to control them, turn them on with dash mounted switch, that. Brings temperature down in 30 seconds! I think installing electric fans instead of clutch fan would solve the issue permanently, all modern cars have that setup.

Going to get a electric fan sensor and replace it it say the fan should come on with the gauge half way up it all started making sense

@@jimmycarter9099 hope that helps you, on my 92 with the M103, the only time it starts getting hot is when using the AC , stop and go traffic, outside temps around 85F, the gauge starts going over the 100c mark which is 212F, that’s when high speed fan should kick in, to test the system, turn key to #2 position, engine off , hvac off, pull electrical connection at 2 pin blue sensor , high speed fan should activate, if does good, if it doesn’t, then you have to find out why, the signal wire goes to push button unit in dash, that unit sends signal to relay in fuse box, from there signal/power goes to ballast resistor by headlight, then to fans. High speed fan is critical to bring temperature down. That’s just a test for fans. The entire system has to be 100%, fan clutch has to be good, in stop and go traffic it doesn’t lock up and cool, it only locks up at 3K rpm when you’re driving, Mercedes did that so your not stressing engine and better mpg. Make sure your engine cooling system is 100%, coolant flow, electrical part of system, if using AC system right pressure’s, pressure sensors etc. As you can see it’s a pain in the ass to have it 100% lol. I spent over 1K getting it to 100%, but still where I live it can be 100F every day during summer time and this German car just doesn’t like it. If I had to do it over I would have removed the fan clutch, installed an electric cooling fan in its place, tied to sensor, that would be more forgiving and work like all modern cars.
