Smoke around belt

I was parked and my car (chevrolet suburban 1999) was idling when i heard a weird noise. the noise was like a grinding and a few squeaks. i immediatly turn the vehicle off when i seen smoke coming out of the hood. so i let it sit a while about ten minutes and drove it to the nearest gas staion and i didnt hear anything again but i notice the heat was off. when i turn the heat on. thats is when i heard a grinding, and squeaking noise coming from inside the car (chevrolet suburban 1999). when i raise the hood, there was smoke and few sparks coming off the ?pulley? that rotates the belt. then the smoke increased. i turned the heat off and the problem seem to go away but i could still smell burning smoke.

Sounds like the a/c compressor clutch is shot. this should only engage if the defrost past of the heat is on. you will need to replace compressor. for now if you want to "unplug" compressor wire connector so it wont engage, that will be ok temporarily

The smoke is coming from the belt because a part has stopped turning ...you need to check which one it is... it could be the water pump...alternator ..a/c compressor...... power steering pump or the belt tensioner.... and your going to need a new belt

There is a grinding noise from the front of the vehicle while driving. All new brakes. The wheel bearings have been checked and are fine.


Is it more like a vibration and humming, than grinding noise? If so it would be a bad engine or transmission mount. To check bearings while driving.. Find an empty parking lot, Make right and left turns/circles. Making a left, if the noise get loader, the right side bearing is bad. and vice versa. Do around 10 MPH while turning circles.

Remove the water pump belt. Start and see if the noise is gone. If the noise is gone you have a bad component that is driven by the belt.

Started engine, heard a grinding noise & smoke


Sounds like one of the accessory pulleys locked up and smoked the serpentine belt. The air conditioning pump would be my first suspect, but grab all the pulleys and turn them. The problem pulley will probably be discolored, and have belt residue on or near it.

Smoke


If the smoke is blue and goes away after it warms up and the engine runs fine. It's most likely your valve guild are worn, they are common to let oil run in to the piston chambers when the engine has been parked for a few hours and most notice when parked over night. Nothing to loose sleep over, good luck

Smoke around belt and sparks on Pulley holding belt


Most likely AC clutch assembly. Have it checked & unplug wires to it, if necessary, to use temporarily, so that clutch doesn't engage.
