Question about 2005 Ford F-150

1 Answer

There is a really load noise coming from the area of the air filter. I think there may be a bearing in the alternator gone bad. Does anyone know if this possible.

Most likely no, check to make sure that all of your pulleys are turning correctly with the belt. If the pulleys are all turning then the thing that is probably causing the noise is your belt. Go buy some "belt dressing" from an auto parts store and spray all over your serpentine belt. Sometimes your belt gets water on it and will squeal afterwards, the belt dressing helps correct this. Hope this works, let me know what happens and I will see if I can help more.

Why is there a ticking noise in my engine?


Richard, It could be something as simple as a bad belt tensioner to something as major as worn bad rod or crank bearings.
Best to find a knowledgeable buddy or a mechanic you can trust and have them diagnose.
Hope this helps you out. Good luck.

My car makes a noise when I drive and someone told me I neeed a cold air intake but I don't know if that's right. But after a little while the noise goes away but I still don't like it.


Cold air intakes are for hot rodding. Try and pin point the area of your noise. It could be your alternator bearing, or an idler bearing, or just a loose belt. Any one of which may go away when the engine gets warm. It could be a dirty air filter needing to be changed. More detailed analysis will locate and find the cause.

1994 dodge caravan was making a noise in the area of the serpentine belt....the belt has since broke..what noise like a gear grinding would be associated with this?


Could be bad bearings in the belt tensioner pulley, bad bearings in the water pump, bad bearings in the alternator (though that would tend to squeal unless they're really trashed) or bad bearings in the power steering pump.  Get a wrench on each one and see which one won't turn.

Scratching Noise


Spray some WD-40 on the pully where the belt rests on the pully while the engine is running and the noise will go away, also make sure the belt is tight enough around the pully, if it is loose then tighten it

My head gaskets gone and the car makes a nasty knocking noise


if you think the head gasket is blown,and now you have a knocking in the engine,replace engine, bearings are probably bad due to water in the oil.you will need special tools to even do the head gasket and timing belt. sorrry no good news

Check vacuum hoses in area where you think it's coming from, for being disconnected or cracked.

Loud Sqeaul/screech from engine upon start up


could be your alternator. at start up. alternator usually has a big load because you just use your starter. it would recharge the battery and after a while the battery would be fully charge, the squealing noise will be gone.

check also all the belts if they are individual belts. use some belt dressings to eliminate the noise. sometimes the belt are just worn out and it would also make these noises.

tnx 4 using fixya,
