Bad bearing in compressor? Bad bearing in compressor?
The symptoms you are describing could be caused by a leaky cylinder head gasket.
Who makes Air Force Ones, Boeing.
Could be a plugged catalytic converter.
Generally the coolant goes in the bottom of the heater core and out the top only because the coolant makes less noise this way if there happens to be trapped air in the system, otherwise it doesn't matter.
The sucking noise is usually a good thing, it means that the drain is working properly, the noise comes from a swirl in the water that goes counter clockwise and pulls the water. That noise is actually air. joe jersey
A whining noise present when turning the steering wheel indicates a faulty power steering pump. As the pump fails, it allows air to enter the system and a distinct whine.
If the compressor is running, the blower is blowing, and there's no cold air, you need freon. If the whining is from under the hood, the compressor may be damaged. That's what happens when running without freon.
if it sounds like a high pitched whining then it may just be your cool air intake
air filter might be clog/needs to be replace or if u have a aftermarket intake the whining noise is nuttin. its just sucking up air int other intake manifold
the Idle Air Control (IAC) is bad and needs cleaning or replaced
when you breath is air and force it out with your tongue it makes the hissing noise
A horn blows air and makes a noise
The whining noise most likely indicates that your power steering is touching something and when you turn, it'd rub against whatever it is everytime you turn OR the belt could be running against a hose, a frame if the motor mounts are broken the bottom air conditioner would be resting against the frame with belt in between, causing the whining noise.
When a car makes a whining sound when accelerating, it might be a fan belt that is not performing properly. If the fan belt is reasonably new, add a few drops of dish soap to the inside to quiet it. If the fan belt is showing signs of wear, like cracks or slack, put on a new fan belt. Also, check the air cleaner. If the air cleaner is missing, the car will make a horrible squealing noise when accelerating.
Could be low on P/S fluid and/or has air in the P/S system.
No answer for you - just want to state that our 2002 Caravan recently (7/09) starting making a load clicking noise when it is turned on. Belt looks good. I'm guessing its the compressor or clutch.
central airconditioner makes a clicking noise when running? any idea what to check?
