Re: Diesel running cold (olio50)

Put a new thermostat in your bunny. It should be 190 degree F. When you drive around town your RPMs are LOW. Little heat is generated at low RPM in a diesel cause not much fuel is exploding. When you are running down the highway you make a lot more heat. Thus, you need a new thermostat or at least the right thermostat to get it up to temp and hold it there. Get a good German on if you can!
