Question about 2006 Ford F 350 Super Duty

Open Question

2006 F350 6 Litre diesel whistling

This is a Kingranch, and I now have a whisling in the cab when I accelerate, also notice when pulling a hard hill when I take my foot off the accelerator I get a pop, pop,pop heard in the cab but definately sounds like air leak. Its been whistling for some time now and this popping of air is just a brand new thing. I worry about pulling my 38 foot fifth wheel this summer. I must say that last summer pulling hills with the trailer behind I blew the air to air lines off a few times. Bought all new and was tested for leaks and the Ford Dealership in Penticton could not find any leaks along with no loss of power pulling hills ect.

SOURCE: 2005 diesel excursion when towing 8000lb

From your symtoms I would suspect a clogged fuel filter. It may seem to run okay without a load, but it requires a larger supply of fuel under load. Anything that restricts the flow of fuel will cause what you described.

Did you get out and lock the hubs? Because that needs to be done but don't leave them locked because you will kill them and your fuel economy.

SOURCE: my 2005 kingranch f350 is intermittently charging.

The problem could be the voltage regulator in the alternator.A faulty signal from the ECU. A bad connection on the battery. Or a bad wire somewhere between the alternator and the battery. I would start with cleaning the battery posts very well and putting Vaseline on them to keep them from corroding. The reason that it could be the ECU is if the battery gets below 12 volts the ECU sees that and sends 12 volts to the alternator to excite the alternator. When the alternator has 12 volts to excite it, it puts out voltage to charge the battery. The way that you can check this is by checking for voltage at the alternator. If you have 12 volts there then the big wire on the alternator should be putting out around 13.5 volts. If you are getting less than 12 volts then you have a bad alternator. I hope that this helps!

Wh does 1st gear jump out on accelerator release ?

There are a few things to check. Engine and transmission mounts replace any broken or perished . 1st gear selector shaft has a indent ball and spring to locate the shaft when in gear, check the spring is not broken. The gear box bearings may be worn giving the drive shaft to much end play. also check gear shift linkage is not worn.

Whistle from turbo.. 2007 mazda bt50 2.5 diesel turbo. . While accelerating I get this whistle noise in the cab. High pitched sort of. it sounds like its around the passenger side footwell.. if driving...

locate the waste-gate and see if you can cover it temporarily while driving. see if this changes it any. It could have a pin sized hole in the diaphragm. just a guess.

I have a 2006 H3 and I just noticed red fluid leaking from the front end yesterday but today there is no leak. I did hear a strange hissing or whistling like sound when I accelerated. Is this somethin

Most likely one of the transmission cooling lines which go from the transmission to the side of one or the radiator expansion tanks has rusted through. It is making that noise because you are driving it with no transmission fluid in it. If you continue to drive it you will break the trasmission.

Hi ,, i have a 4 litre mazda t4000 ,, its a horse truck ... it blows a fair bit of black smoke when going up hills and some white smoke when i start it up ... should i worry ... thanks

The black smoke is unburnt diesel fuel- lift your foot. When I was learning to drive diesel trucks (many years ago, in one of these trucks) I was taught that when going up hill under load, I should lift off the accelerator until it just starts to die off, then give it a little bit just to hold revs. No more black smoke.

When you start it, do you let the glow plugs heat for long enough? (Does it have them? I can't remember).

Weak Torque?

has this been a problem since you had truck? or just started? truck might have a gear ratio not suited for the pulling you do.
