2005 Ford F-150 Belt Chirp Noise Vexes Veteran Tech: Video

YouTuber and Ford technician Brian Makuloco of the channel Ford Tech Makuloco has cranked out numerous informative and helpful videos over the years, many of which have been dedicated to the Ford F-150 and its much-maligned three-valve Ford 5.4L V8 Triton engine, as well as various issues related to heater cores and starters, among various other parts. Now, Makuloco is back with yet another interesting video, this time centered around a 2005 Ford F-150 belt chirping noise that proves to be quite irritating.

This 2005 Ford F-150 is also equipped with the 5.4L Triton V8, but it’s experiencing a bit of an unusual problem with a strange fix, to boot. The issue is that the pickup was making a loud chirping noise that many would assume has something to do with a belt. However, after doing a little digging, Makuloco discovered that the noise was actually coming from the driver’s side valve cover.

The owner of this 2005 Ford F-150 recently purchased it with 245,000 miles on the clock and brought it by so that Makuloco could go through it and take care of all of the potential trouble spots that these trucks typically present. After performing all of that work, the engine started making the chirping noise after it warmed up and settled into idle.

After doing a little digging, Makuloco discovered that the culprit was nothing more than a loose spark plug – the owner had changed them out prior to bringing it into the shop, but one of the plugs didn’t seat correctly. As such, gases were leaking right through, and after further inspection, Makuloco found that the one particular plug appears to be defective. Thus, such a problem is quite likely to happen to someone else, and if it does, this video could save them a ton of money in the long run if the same problem is misdiagnosed by another shop.

    I have a 2010 Ford F150xlt Reg.Cab LB 4.6L 2V. When I first crankup only when JTS real cold it makes a buzzing noise for about 5-10seconds then quits ,sounds like coming from alternator, not sure , alt. is New but use to get this noise even with old alt. Do you know what this whinny buzzing noise may be? Or is this Normal because engine is cold?

      Hey Philip, I have a 2006 F-150 that do the same thing every cold morning since I bought it in 2011. I narrowed mine down to the power steering pump and I have had no problems with it. I hope this helps
