87 190e 2.3-16V engine temp questions
 

Just curious. When I'm driving along the highway at steady speeds, the engine temp stays a little over 80 degrees. When I am stopped for an extended time, say at a stoplight or Tim Hortons drivethru, the temp goes up to about 105 or 110. But then when I start driving it goes back to a little over 80. Yes the fan kicks in and does drop it somewhat. The rad is about 1 year old. Coolant is recently changed. Any ideas if this is normal?

Those temps are normal with the A/C off! If you have a 3 pole GREEN temp switch for the fans you can lower those readings by using a RED 3 pole switch.

As "Doc" says, those are normal. The engine fan clutch activates at 100 degree C, the electric aux fans come on at 105 degree C.

the temp seems like my 1987 MB 190E 2.3L 8V.

thanks alot for the replies. I had a feeling they were normal. Just wanted to double check. Thanks!
