Why does my 1997 mecedes benz e420 run hot when I turn on the air conditioner
Couple of reasons. You may need to have the Radiator backflushed to remove sediment. You also have an Electric cooling fan which may be malfunctioning. They (fans) often have more than 1 speed and high speed may be broken so it can not keep up with extreme heat.
Some fans use more than 1 relay to switch the fans and the second stage relay may be bad.
Overall, the A/C coil is placed in front of the Radiator and depends on airflow to function. This makes the air available to the Radiator much hotter so the Radiator is having a hard time cooling the engine. The Electric radiator fans kick up the airflow to help both systems out.
A dirty radiator, old antifreeze, etc. can affect performance.
I hope my solution is helpful. Radiator shops can service most Brands.
