Question about 2003 Ford Mustang

Open Question

2003 Mustang experiences loud squeal and chugs to stall.

6 cylinder starts fine...after a couple of minutes the engine will squeal loudly, then chug to a stall...will continue to run if I press gas pedal but will cycle back to squeal and then stall again. I took off the tension belt and it still squeals and stalls. Thanks for your help!

SOURCE: multiple cylinder misfires

cross the wire, probably the firing order problem.

Did you change the distributor cap, sometimes the distributor cap inside cracked, you won't see it, take off the distributor cap, but you have to remember the wires' order, lightly drop the distributor cap see if you can hear the cracking noise.

Or during the dark night, get a dark place, start your engine,see if there is spark out, fix that, maybe your car will run better.

When I had my Union 76 service station, I have solved several cases like thiat.

I had a big Sun electronic scope from 1973 to 1984, during that time, something I could't ping point where the problem was, therfore I used many experience, maybe I am wrong, but you can try it, I like to try everything.

Hope this ccan help you, good luck.

SOURCE: squealing belt

Causes of problem like yours can be:

  1. the alignment of the pulley of your alternator and the alignment of your engine's pulley. you may check it by just looking at it, be sure they are precisely parallel with each other.
  2. The size of the opening of your pulleys, you try to measure it using a caliper, they should have the same mouth size
  3. loose pulleys causing wiggle
  4. rusts on your pulleys
Hope I helped you

Belts stretch from new. Try to tighten them again. Hopefully the are not glazed or this may stay with you.

2000 montero sport: There's a loud squealing noise coming from the engine. What could be wrong?

Squealing is most common with loose or worn belts, I would start by replacing the drive belt on the front of the motor and go from there, Its easier to troubleshoot a squealing motor if you know that the belt or belts are good.

2002 mustang 5 speed 6 cyl.....does it have clutch fluid and if my clutch was goin out would it make my car die when i depress it? when i start the car there is a loud squealing noise.....also there is a...

yes hydrailic and no will not affect engine. Engine problem is just more noticed when transmission not engaged.
Squealing is probably pilot bearing--not a big deal.
Tapping--maybe lifters pumping up
Engine light--get car scanned and report trouble codes back to us.
Autozone and Advance, among other parts stores, offer free scans.
