2007 Lincoln towncar signature 29,542 orig miles, yes that is the correct miles.
Electric fan would not come on even with ac on, Jump fan directly to battery it worked.
Replaced radiator fan module and now it works like it should.
Read on pros and cons or also replacing the fan when you replace the radiator fan module.
Do I need to? If it aint broke don't fixit ,or should I?
Is there a reason why you should replace both at the same time?
Also if radiator fan module goes again, can I just jump the fan to the battery to get me home or is that a no no?
How I miss the simple reliable belt driven declutching fans easy to fix cheap and easy to diagnose.
Pure greed on the car makers to put this unreliable expensive junk in cars.
Been repairing my own cars for 55 years.
Thank You in putting up this great site Scotty.
Well first off, I like electric fans because they don't add load on the engine (not running off the accessory belt anymore) and can be controlled more accurately with the ECU. But I digress. If the fan itself is working perfectly fine when jumping to the battery, then you don't need to replace it. You only need to replace the fan module if it doesn't operate the fan correctly. Some cars have the fan and module as one unit which have to be replaced altogether, but yours is separate.
If the fan module goes out again while driving home, you only need to jump it if you're going to get stuck in traffic OR if you're going to use your A/C. When the car is stationary, the fan helps suck air through the radiator to cool the engine; it stimulates air flow when stationary. When you're driving on the highway, there is sufficient airflow through the radiator to cool your engine. Technically the fan becomes useless when driving at highway speeds...
