Seventh Series Radiator Thermostat Adjustment

Posted by LemuelGulliver On 2017/6/5 20:48:06

Hello!

I've got a couple of questions regarding some minor mechanical problems, but for the sake of the forum archives (say, someone looking for the answer to a particular problem) I'm going to start two separate topics.

I've been working on a 726, getting it back into roadworthy condition after some lengthy time garaged. One particular problem the car has had for decades is that the thermostat for the radiator isn't properly adjusted, and the shutters open too late, causing the car to overheat. The solution which my grandfather has always used was to simply prop the shutters open with sticks, which works well enough, but I'd like to get the car back to full functionality. The problem is, as I understand it, that the thermostat is buried under the radiator shell, and to get at it the hood and shell has to come off completely. That's something of a pain in the butt, so before I do any of that kind of work I figure that I should ask here and find out if anybody has any advice for adjusting the thermostat. Is there a way to adjust it and check its adjustment without having to take the front end of the car apart over and over again?


Thanks!
