My 380SL's twitched.

Again, this is not my area, but when the AC is on, isn't heat dissipated through the condensor, which would raise the temperature of the air going through the radiator.

Common problems which would be made worse by this:

- a marginal radiator in terms of flow,
- maybe your fan clutch is not turning the fan fast enough at idle
- aux fan not coming on as it should
