I posted earlier about my 81 240d running cold even in the summer. Now it barley makes it up to 60* after a long haul.
I put in a new mb T-stat and run a 50/50 mixture of coolant. I have checked the engine temps/ head temps with my infared heat gun and she does run cool..around 150* at best. My gauge appears to be fine.
btw.. I did put in a new bosch water pump a few weeks ago.. had a small drip from teh weep hole...................so my question is....

should I run cardboard in front of the radiator ?.........or
should I remove the fan and and fan shroud until spring ( and watch teh gauge) when temps get above 65* ambient?
