I am the original owner and when the car was new the cooling fans came on only when the car was hot and would stay on after it was turned off until it cooled. I have had nothing done to the engine except for a several spark plug condensers, but have replaced three air conditioning compressors and the radiator along with the fans. I was completely surprised to find not a speck of dirt or grease inside the cover, a photo is attached. Because of an oil leak at the back of the valve cover it was necessary for me the remove the cover and replace the gasket. I use the car as my primary transportation and I has plenty of power and does not require oil addition between changes, which I have done every 3000 miles. My 1996 XJ6 currently has 340,000 miles on it and everything appears to be working ok, except for the coolant level sensor.
