I noticed the other day that the radiator cooling fan keeps speeding up and
slowing down. It seems to start doing this when the engine temperature reaches
70 degrees. The normal running temperature is 90! It appears to be putting a large strain on the electrics as the headlights become noticeably dimmer when the fan speeds up. It stops when I switch off. Even if I allow the car to rest for about 15 - 20 minutes to allow the engine to cool before starting it again, the fan starts to do the
same thing when I switch on the ignition before starting the engine. I have had this car a few years and know that this is not normal behaviour. Coolant and oil levels are fine. Climate control is not switched on but it appears to be working properly when I do switch it on. I took the car into a garage the other day and they were not able to diagnose the problem. The only time I have ever noticed this fan in the past was when it kicked in for a minute or so after switching off the engine in the summer when it was very hot. Now it seems to be on almost all the time but not at a constant speed – it speeds up and slows down every 4/5 seconds.
