i have a 01 lincoln ls 3.9v8. i am fairly mechanically inclined and have worked on the car sevral times, but this problem has me scratching my head. It has happened 3 times now. the engine temprature alyways runs at halfway on the gauge. and it will start like this. i hear a noise that sounds to me like an auxillary fan from underneath the hood(that i never otherwise hear) then within 1-2 minutes the temp gauge starts climbing untill it reaches the H then of course the check engine temp warning comes on, then a minute or so later the reduced engine power warning comes on. this process takes less than 4 minutes start to finish. in the mean time i will pull over and there is no steam, no boiling, no obvious signs that the car is overheating. i let the car sit for 5-10 minutes then get back in start the car and temp gauges is sitting on halfway as always and car runs fine then. it is my opionion that the car is not overheating but that something like the thermostat or something electrical is sticking or misreading. and the car being turned off is reseting this. any ideas or any one experienced this? all info and help is greatly appreciated in advance.
