Answer to your question is -
Check with your local BMW Dealer. They recalled the radiator caps on a lot of the E32 because they were having problems bring the engine up to proper temperature or overheating.
Or you can do what I have done in the pass, call Bosch in Munic, Germany and talk with the head instructor over there. He happens to be one of the engineers and designers of the 750iL and very knowledgeable and read the BMW service manual.
