If its a squealing noise it probably is a belt, check for oil residue or cracks , and belt tension

Whining would be the pump or low fluid. Squealing would be a loose belt.

Sounds like you have a loose belt on the compressor. Check the engine belt for loosness, or frayed edges (might be time to replace it too). You can put a dab of oil on it- sometimes that will make the sound stop for a short time but the real fix is to tighten or replace the belt.

Loud sound from the engin when start and agos after 10 minuts


What kind of noise ae you hearing ????,,,

If it is a screeching/squealing sound this might be the fan belt, which when it gets loose, can slip and squeal on the pulleys. It should just ned to retensioned or at worst case, replaced.....

If it is some other noise, please let me know and I will hope to identify it for you.

Loud noise when air is on had belt tension replace still making noise now im told its the engine mount


This is hard to answer without hearing the noise, a 2005 altima it would have to have alot of miles or have been drinen hard to need a motor mount, the compressor could be noisey or may be a loose heat sheild on the exhaust,a squeal noise would be a belt a rattle noise could be a pulley going bad or something loose, when ac is on it puts more strain on engine causing things to shake,i would have a second shop just look at it before doing anything, see if they both come up with the same problem, and dont tell them what the other shop told you about the mount, tell them only after they tell you its something else.

Van wont start, loud, has a burning smell and the oil light is on


I'd feel best if you can find a reputable mec and have it looked at. There are a mess of things that can make loud noise. You could have anything from a bad berring to a blown engine. When your'e on the road remember go to someone who is reccomended or a national chain or dealer..

Strange loud buzzing noise on 1997 Ford Explorer XLT


Only thing that comes to mind with description is maybe heat shield on exhaust, getting loose. Wait until vehicle is cooled off and get under there & check any heat shields you see wrapped around or near exhaust, above it attached to floor of vehicle etc, and give them all a little shake or rap with rubber hammer or similar to see if any rattles are present.

I have an 03 nissan altima engine makes loud clicking noise


1st check the the oil level and the vehicle's oil type.(owners manuel) 5w30-10w30
10w 30 is a thicker oil and could possibly be causing this.(Moves more freely through the engine heats the oil)

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.
