Thanks for the advice!
I will have to check the relays.
i just want to make sure when it gets hot, that fan kicks on.
I use it to plow with, and on the highway the plow blocks the airflow!


My '72 W200 has a plow on it as well. With a 180* thermostat, driving around town without the plow, it would sit around 180*. Driving with the plow, it'd hit 210* Hopefully the mercedes fan will fix that.



Yeah i hope both of our fan problems are fixed!
I also installed a 160* thermostat so hopefully everything will work good this year for us both!
