Thank you so much.
I'd like the temp to be a little higher. It is now around 80 degrees C and I want it to be in the 87 degree mark.
Maybe you can answer this question. Why old MB thermostats always get in that not fully closed position? In my other two cars, I have replaced the thermostats on both and both times, the temps were not high enough. After a thermostat replacement, the temp went right up to 87 degrees.
