Actually I don't have a clutch fan anymore, converted to electric puller fan with an 80/88 switch on the rad. Thermostat is 88 degrees and holds the engine temp pretty steady at the half way mark, it drops down a slight bit at highway speeds. Just went over the whole system when I changed the hoses, might drop in a 91 degree stat next time around for better cabin heat and to improve my highway fuel economy.

Mr. Ilia - I did follow the guide on M42club but made some slight alterations using a M44 hose to bypass the TB heater plate.
The major difference between my 318is and an e30 M3 is that the noises come from the engine and not the passengers
