Ford 4.2 V6 Squeaky Problem Part 4

New (2nd) water pump is not the root cause!
But, I have a "off the wall" lead on what it could be (been there before, haha)....

Just going through the squealing belt thing on my 2000 E250 with 4.2L. Glad I came across this.

Good luck on your repair! I just ordered a new cam sych and hopefully I can tackle that next weekend. Looks like I need to drain the coolant again to remove the heater pipe from the water pump to get it out of the way as well as the EGR pipe and valve itself. Ugh.

After over 50 years in the auto repair industry I have seen the distributor or sensor drive squeaking quite a few times. Other things I have come across are belts being too long even though the manufacturer will say they fit the application. If you can find a Goodyear belt for a squeaking belt problem it always took care of the problem. Most of all finding the problem
first will save a lot of work and money.

Yes on this one the root cause was the cam sensor drive as it turned out (R&R on 2 other videos). I had never heard of this problem before. Not being a pro mechanic I for sure have not seen it all!! Thanks for the comment!

Having the same issue with a 2003 5.9 Cummins, changed to a gates water pump, have used two new belts, one a Goodyear heavy duty and one Dayco, have used two new Dorman tensioners, two new idlers (one Dorman, one LITNS), changed Alternator, tried two new AC compressors, changed fan clutch which was bad, power steering was changed once, so I left that alone and the squeaking is not coming from that area, I’m going nuts and the squeaking is loud. Going to take the belt off and just run the engine to see if it stops and isolate the problem. One test I did was squirt water on the groove side of the belt and the squeaking stops, so many say it’s either the belt or pulley misalignment but I don’t see it…driving me nuts!..oh, I also changed the camshaft sensor bc I had an error code and that was fixed, I don’t show any codes….

DItto- cam sensor drive bearing squeak on my sons F-150 2007;. Looking closely on the new oem drive housing, an unused and untapped boss indicates engineering specified a oil lube point for the shaft bearing;
bean counters: "we can save 0.01343 cents per engine if we don't drill and tap that boss"..... and we will get to sell an overprices engine component in the future"....
