Electric fan???

To match the airflow of an engine-driven fan, you need a powerful electric fan. The 2-speed Taurus fan move a lot of air and is popular with hot-rodders.

The Contour dual fans move a lot of air, and fit nicely on a 26" radiator. Keeps my 451 cool in mid-90's humid Missouri summers :)

The electric fan turns on from refrigerant temperature, so its main purpose is to cool the evaporator when idling. Even that isn't sufficient, since the AC gets noticeably warmer when sitting at a long stoplight. That is also true for my 2002 Chrysler minivan, and yes I verified that both fans turn on. Once you start moving 30 mph, the AC gets noticeably cooler.

I believe you meant, "cool the condenser" :poke:

Sounds like you don't have enough condenser if both fans are working and the A/C warms up. Or did you do a conversion to R-134a on your MB diesel?

I used to own several (220D, 240D, 300SD) and on the 60 hp 220D I'd turn off the a/c when I needed every hp sometimes :D
