Asked by jburke2046 Aug 17, 2013 at 09:54 AM about the Lincoln Town Car

Question type: Maintenance & Repair

After starting, and through warm up to normal operating temp, the electric radiator fan on my Towncar does not switch on.

If I have my air conditioner turned on, it switches on sooner.

Is this normal

Yes...the engine has to be brought to the operating temperature of 195...until it gets to this point fans will not come on, as the sole purpose of your thermostat is to block the coolant flow until operating temperature is reached~....now it it's starting to overheat, we must look 'pon the reasons~

Most cooling fans turn on around 210 to 212 degrees, that is why it is imperative that you maintain your cooling system properly with a proper mix of antifreeze and water and a good pressure cap. The cooling fan should also turn on with the A/C compressor, some systems are tied in with a high pressure switch that turn on the fans when it reaches a predetermined pressure setting. So to answer your question yes it is normal as long as your cooling fan turns on around those settings.

If it isn't overheating, don't worry about it. If it isn't working properly you will know soon enough. The LTC cooling system works great unless something is broken, then you will know very quickly.
