View Full Version : Mercury Crankshaft Position sensor for 4.6 engine:

I have the manual for the Mercury/Ford models, My problem is that the manual makes the removal and installation seem cut and dry, but while trying to replace the sensor, the air conditioning compressor pully won't give me enough room to remove the old crankshaft sensor. Is there a trick to this that I am not seeing? This is on a 2003 Mercury Grand Marquis with a 4.6 engine.:confused:

I would try removing the drivebelt, then unbolting the air conditioning compressor (without disconnecting the refrigerant lines) and see if that will give you enough room to get the sensor out. If it doesn't, then the air conditioning refrigerant will have to be discharged (recovered by a licensed technician) and the compressor will have to be removed completely.

Thanks for the info, I only need maybe another 3/4 of an inch more room. I really don't want to completely remove the air compressor, so I'll try your suggestion. Thanks for the reply, much appreciated!
