    2012 Navigator Cylinder Head Temperature Sensor

    OK. I decided to quit screwing around and I removed the intake manifold. Sure enough there is definite rodent damage. 2 questions. 1. Can anyone tell me what this is? Can I repair it by wrapping / sealing it up or does it need to be replaced? I don't even know what it is. There are 2...

    2012 Navigator Cylinder Head Temperature Sensor

    Well .. I definitely found a wire that needs some attention. This connector comes from under the driver side of intake. It really couldn't be much harder to get at, and while it is definitely A problem, I don't know if it's THE problem. I'll guess I'll start trying to figure out how to repair...

    2012 Navigator Cylinder Head Temperature Sensor

    Thanks. I'm going to start tracing wires and looking around for evidence of a rodent or other funny business. Seems too coincidental that the cylinder head temp sensor AND the AC clutch start misbehaving at exactly the same time. Generally speaking, I don't believe in coincidences. Very...

    2012 Navigator Cylinder Head Temperature Sensor

    All- I feel like this is a long-shot, but going to give it a go anyway. I have a 2012 Lincoln Navigator with the Ford 5.4l 3v engine. I had let a friend borrow it for a while, and now that I have it back there are some issues. Dead battery, AC Compressor Clutch not working, temp gague in...

    Nice! I mentioned above about my 2012 Navigator. I did the plugs and timing chain/tensioners/cam shaft phasers. Nav runs like a top now.. hope it stays that way! I think I'm coming up on 300k miles.

    2012 Navigator Radio Popping

    Thanks .. I can definitely appreciate that it could still be something related to a short in a speaker somewhere. Since I really don't KNOW what is wrong, I can't really say for sure what the problem ISN'T. That said, there are a few things that would make me question that the problem is with...

    2012 Navigator Radio Popping

    Alright. Here is an update. Again, I'll try to be brief. I removed the original amp and returned the one I bought from 1FactoryRadio.com They were very easy to work with on the return. I decided to open the thing up and at least take a second look around. Here are some photos: Forgive me...

    2012 Navigator Radio Popping

    Awesome .. thanks for the information. I did open it up once to take a look. I was quickly overwhelmed just looking at it, so I put it back together and just started my quest for a new one. I'll go take another look now .. thanks! Just saw your other message about the programming. I have...

    2012 Navigator Radio Popping

    Hey All- It seems like there are some known issues with the radio, or maybe specifically the THX amp. Mine started to fail about a year ago. It would click and hiss and pop (video below). Eventually it got so terrible I had to disconnect everything. During the course of my trying to...

    I've got a 2012 Navigator. Original trans and engine .. has the 5.4l 3v. I bought it used with about 90k miles on it. It's been an "ok" vehicle. I think I've got about 235k miles on it now. I just had the timing chains / tensioner / cam shaft phasers job done to the tune of about $2700, but...
