I'm just getting China drivable, and need to flush the motor a tad, so I just filled up with water in the block and radiator. I also burped top hose as much as possible. No overflow bottle on '80 240D btw.
Driving the car with the AC on, it was hovering around the 85-90 degree area for the first 5 minutes or so. {ambient mid-hi 80's} Then it creeps up the the 100 degree mark, and passed it just a tad.
Super clean, almost new looking radiator from looking through cap opening. New thermostat.
Is just running water enough to account for this higher temp? I've heard of folks running a few hundred miles to do a citric acid flush, so it would seem water should be OK, but yall tell me.....
Thanks
