Whining noise on my 2006 cadillac cts.Had the power steering pump replaced yesterday. Noise is back again today. What is it?

Had a whining noise for about a month. had my local garage check it out & they flushed the power steering liquid & replaced. Did not work, next day whining again. Took the car to a cadillac dealer, they said the pump had a crack in it, needs to be replaced. Had it replaced & the day after it was replaced the whining started again. Help!

SOURCE: Replace 2005 Cadillac CTS water pump

drain the coolant.remove belt by rotating belt tensioner cllockwise. water pump pulley will require a holding tool to keep it from turning while removing bolts. access to air ratchet can sometimes eliminate the need to hold but be careful cause thats a good way to skin some knuckles. also make installation more difficult to obtain proper torque. after pulley is off just a few water pupm mounting bolts remain. clean and dry gasket surface very well before reinstalling.

The problem is the wheel bearings that have the ABS sensor attached. Check the computer for the code as there is also an up date for the wiring sytem with a jumper for $60 fix that possible could solve the problem.

I do not mean to be hurtful and it will take some time to do. Maybe all day if you have no experience. If you need instructions just maybe you should have some do it for you.

Whinning noise when engine is off

Whinning Causes
The whining noise you hear coming from the power steering pump is one of three things. The first is more of a loud "hush" than a whine; this is the sound of fluid rushing through the bypass valve when you turn the wheel all the way to one side or the other. Sometimes the bypass valve malfunctions or doesn't open all the way, causing pressure to back up in the pump and cause your engine rpm to drop. The second and third causes result from cavitation -- vacuum pockets created behind the rotor's vane blades as a result of extremely high pump action -- or air in the lines.

Have it checked that the power steering fluid is enough. If so, could just be that the system needs bleeding.

Whining when i press gas

normally, the only part of your automatic transmission that will make a whining noise is the pump. it usually whines when iether the fluid is low or more commonly when the transmission oil filter is getting plugged up.

the power steering pump will also make a whining noise too.

turn the wheel all the way to the right and hold steady pressure against the stop. this puts maximum force on the power steering pump and, if the power steering pump is the one making the whine, it will change the sound of it. (usually louder).

if the trans pump is making the whine noise, it should sound different in neutral compared to drive. this test will really only work if it make the noise without the vehicle moving. if it wont do it at idle hold the rpms at 2000 or so.

if you decide the noise is coming from the transmission, and the transmission filter has not been replaced (assuming you installed a used transmission), replace the filter by removing the oil pan.



oh and also, if it is the power steering pump you should be able to make it make the whining noise while the vehicle is stationary. if it wont make noise unless its moving its not the power steering pump.

Where do I pour the power Steering Fluid?

Pull up on the engine cover. It should pop off with slight force. The power steering fluid reservoir is under it.
