Hi Mattman:
Thanks for your reply. My mechanic is a German engineer who works on and sells Mercedes, Audi BMW and VW as a hobby and has been doing it for many years and really knows his stuff. He has done my timing chain and other stuff flawlessly. When he says the rad is perfect,I believe him as he shows me why he says things - not "just take my word for it". The only thing he was mentioning is that he thought the temp. switch (mounted in the air cond. circuit) was only for freon temp. Is there another temp. switch on block for engine temp that is also in parallel with temp switch for air that would kick in aux fan???
I will look for the mod you mentioned in performance forum. Instead of trying to find new guage like one in dash, I have a laser infrared non-contact IR Thermometer at work which is very accurate. I will have to wait until spring when it warms up up here, but I will check the block temp. with it. Thanks for tweaking my memory!!
When you say this car has been well cared for you are not wrong. 2 years ago we stripped it and removed the interior and front & rear glass and had new metal put in wherever there was any sign of rust. Then stripped the car to bare metal and had it repainted and hand polished to a Factory shine. She looks like from the showroom!!! Even has chromed washer arms on euro headlights. Definately a looker!! Will have a digital camera by spring and will post pictures of her. Thank you very much for your assistance. With everything I have done so far you can appreciate why this problem should be corrected properly.
