You went through the true pain of DIYs and educated us on every detailed step, for that you have my "thanks".

Wow. what a trip.

My 85 300D Euro was getting to 115-118 degrees everytime out.

I bought one of the Auto-Zone thermostats and while taking out the old one, I noticed it had been installed backwards. I turned it around and BINGO, I can't make it get over 90 degrees, whew.

A question, anyone: What makes the Aux fan come on? After a five mile trip (75-80 mph) the fan is not running.
