fan is hotwired so it on whenever the car is on. A high flow may improve the situation.

But here a twist to the story.

Took the 240D today. New thermometer, same one use to post the temps above.
The car vents temps ran at 42 down the highway, 40 at one point, Vs. the 40 and 38. Outside temp is about what it was yesterday driving the 300TD.

Starting the car, then ran down the road, it acted like the 300TD. Very hot until just outside the neighborhood. Cooled down nicely but as I said 42 degrees in the vents.
I will put the guages on the car, check for leaks with the sniffer and the dye light. See if the R12 is leaking which may explain the higher temp in the R12 system vs. the R134a system.

I'll post when I get it done.

Tangent, sorry

Go here to learn the difference. Basically the same size parallel flow condensor is 30-35 % for efficent so the removal of heat from the freon is better, which with a converted R12 to R134a system you need.
