How to remove and install oil level sensor?

Most Fords I've seen and especially theolder designs like 5.0L have a simple screw-in type oil level sensor. It looks like a hollowed-out hex bolt and the entire assembly is 1 piece that simply screws in-from the OUTSIDE of the oil pan-like a drain plug does. (OBVIOUSLY, Check the oil level in the pan with the dipstick before unscrewing it.) Once the old one is out, inspect the pan threads and the area right around them for possible damage as the sensors are sometimes struck by something that may bend the pan where the sensor screws i-and may cause a crack that could leak, so don't ignore the possibility. (IF IT IS BENT, you may want to think hard about using a regular bolt that hugs the pan instead of sticking out, as whatever happened before may happen again-with worse results. CLEAN the connector very well before reattaching it, flushing out all the old grease and/or gunk first with solvent, then burnish the contacts (if you have to) to get a shiny surface on the metal pins or sockets and use dielectric grease unside for the best connection and longest protection. (If there is corrosion there you'll likely be needing the dielectric grease for more connectors, such as indicator, stop and turn signals.) To save yourself some possible unneeded work, unclip the connector FIRST (before even unwrapping the new part, as it could be returned if not needed) clean it out and examine it closely as sometimes the connection is the problem, not the sensor. It can get corroded inside ANY connector, ESPECIALLY SO if you're in the Snow Belt or anywhere the roads get salted. If its got green crud inside, that's usually a sign of corrosion of the metal contact pieces and/or the ends of the wires and may very well be the issue. In any case, if its not SHINY clean inside, clean it out and try reattaching it. If it then works, the sensor is ok and you could just put some dielectric grease inside the connector and you're done. If the connector is very bad, they do sell that connector with pigtails to replace it with. The engine can function fine without the oil level sensor (as you probably already knpw) , so if you want to put a bolt back instead, you could just clip the wires, tape then individually so the idiot light CAN'T come on, however, you WILL have to remember to check the oil.....all by yourself.)
