Start up from cold in am. 5-6 mls. up the road no reading on temp. gauge! More miles later Thermo fan is running at full speed. Then I stop the car, turn off ignition. Wait a 1min.or 2 then restart. Car then runs ok for the whole day! often runs ok for a day, week or longer without the fault! This has been going on 6-9mths. now. Merc Dealer/s have had the vehicle 3-4 times & even loaned me a car twice but still unable to find or experience the fault! Pls.help
