Hello all.
I have noticed that my engine is tending to run hot when stuck in traffic (about 110 deg) it is a 190E 2.3, 1992. It is clear that the cooling fluid needs change.
However, I have noticed that the A/C stop cooling when the engine reachs that temperatures, as if it was unable to do more, is this normal?

Thanks!

Check the Aux fan.

Well, at least it works when you turn on the A/C with the engine at idle and cold, so I don't have reasons to suspect on it, right?
Thanks

I had a problem with the Aux fans where they were drawing too much current and not turning very fast. The car would start to overheat at a stop with the AC on. As soon as I replaced the fans, the engine temperature stays between 85 and 95.

The defective fans were also blowing the fuse as soon as I engaged the high speed mode.

You may want to turn the AC off and see if the car still overheats. If it does, then you may have a cooling system problem.
