Subject: Re: SAAB 9-5 Overheating Issue


Don't know about 9-5 Saabs, but this holds true for most cars: - The eclectic fan either has two speeds or there are two fans - low and high (most likely two speeds with a resistor for the low speed) - The low speed kicks in now and then during normal driving; high speeds is for serious overheating or when the AC is on. - If something goes wrong with the low speed you may never notice it if the car is constantly moving (air cools it), but if you're stuck in traffic it will start to overheat. Once it gets almost to the red, the high speed will kick in and bring the temperature down. - In the summer, with the AC on, the high speed is on all the time, thus hiding the porblem with the low speed fan. - Best way to confirm that is to let the car idle for some time - 30 min. or more. See if the temp raises and see if the low speed kicks in.
