'00 Pathfinder, makes a squeaky noise when engine starts

It only lasts for a second but it sounds horrible. I don't know if it's the engine or a belt or what.

More than likely the belt is glazed or it is a pulley bearing that is lacking grease. Easiest way to figure this out is to use a can of WD-40 and, with the engine running, spray the pulley area of the alternator, then the waterpump, then power steering and A/C....then the belt last. Do one at a time....this should narrow down your troubleshooting......but sounds like a glazed belt.

What causes a squeaky sound from the engine of an 2000 Isuzu rodeo when engine is running?


it could be one of the belts. if you put a little wax or brake fluid on the belt in a couple of places and the squeak goes away then you either have a loose belt/s or the belts/s need replacing. if no change it could be the timing belt making the noise.

My 2000 BMW 328i has a horrible squeaky noise when it is cold and stops after about 15 minutes what is the problem and how do I fix it?


I assume that the squeaky noise stops after 15 minutes, not the engine. If that is the case, you may have a very worn belt. This won't cost you a ton of money. You have a serpentine belt on your car, so that is a likely culprit. You may also have a bad battery, which in cold weather would perhaps have just enough to start the car but would also demand the alternator (and by extension, the belt) to provide enough amps to recharge the battery after a severe draw,
Before the winter, I recommend a new serpentine belt and a new battery, after a test of your alternator output and the battery at a good shop. You should not expect to spend more than $200 max, if everything is wrong.

Short duration screech when car is started. Last longer in cold weather. Had top two belts replaced within last 24 months. apparently there are three belts.


One of the belts is loose. I would say it is the Alternator Belt.
What happens is that when you use the battery to start the car, the alternator immediately attempts to charge the battery back up once the car starts.
If the belt is loose, the belts slips some, making that horrible screech, until the battery is charged enough that the belt no longer slips, because the alternator no longer needs to make as much power, and the screech goes away.

Check to see that your alternator belt is the next one to replace, and tighten it up to specs.

My check engine light is on. There is a squeaky cricket noise when the car is in motion; it is not a loose belt. I don't want to take it in and be overwhelmed with major engine problems. Any ideas what it...


for the check engine light:
-you can go to auto zone and have them hook it up to the computer for free!!!!!

for the squeaky cricket noise:
-could possibly be a wheel bearing starting to go bad, or possibly a wear sensor on the brakes....

that is only if it makes the noise when the vehicle is in motion.... if the sound is there while it is sitting still, then you could have a pulley bearing going bad... hope this helps.... please rate this...

Loud squealing noise


The noise is most likely the serpentine belt. Check it's condition and that of the belt tensioner. It sounds like the belt is slipping, causing the squealing noise u describe. As the belt warms up, it's getting a better 'grip' and the noise stops. Turning on the heat also turns on the a/c in newer cars, this added drag on the belt (one more component to turn, the a/c compressor) would explain why it happens when u turn on the heat. Is the belt original? If yes, it's time to change it, and check the belt tensioner to make sure it's doing it's job of keeping the belt snug on all the pulleys. Let me know how u make out.
