THAT sounds like a bearing in either /Alternator/belt
idler/water pump/or powered steering.
You say when it get to 70 but what is the rpm not speed as all pullys are differant sizes so rotate differant speeds OR check the power steering belt and others for cracks or loose.

I get a whistling noise inside the car when you reach 50 to 70 mph but goes off above 70 and below 50 what could be the cause


Most likely is the door seals, check there are no holes or splits. If it has always been the same it could be the mirrors. It depends lot on the age of the car as well, but I would check the door seals first.

I have a 2003 ford expedition with the 5.4L that whistles at 30,60, and 70 mph when its cold out


Not sure the significance of the cold part. Typically when I hear a vehicle whistling, if it's under the hood, I always suspect a vacuum leak. A late model vehicle like that should throw a check engine light and some trouble codes if it were a vacuum leak.

Whistling when accelerating outlander turbo diesel


turbo whistle is common as it comes from the tips of the compressor wheel passing through the sound barrier and the turbulence occurs. IN the older trucks you would the turbo whistle as the engine reached full RPM just before a gear change. In smaller engine it is not do noticeable as there is an excess of air pressure that keeps the compressor wheel at a lower rpm and the pressure is dumped out. Turbo compressors reach revolutions in excess of 120.000 rpm under full load If it has just started to make the noise then check the intercooler system for leaks--loose clamps--- splits - Have the turbo compressor checked for damaged fins from the ingress of fine dirt from a bad air filter---check the air filter is not blocked as the turbo speed may result from running in a partial vacuum ( no load on the compressor wheel)

My engine is idling very high


High idle speed is an indication of a vacuum leak. Listen for a small whistle. Find the whistle sound, you will find the leak. Now repair the bad hose, or broken plastic tube with a small chunk of hose that will fit over the tube. If it is more major, it could be an intake manifold gasket. The engine uses an idle air motor to control engine RPM. After fixing the vacuum leak, the engine may not idle at all, until you drive the car for about 5 minutes above 40 MPH. The idle air motor resets itself to 0.

Whistling sound can't keep car from running hot


It could be your power stearing pump. But it sounds more like a vacuum leak to me. Does it go away when you speed up your motor or get louder? It also could be just a belt. Or a tension pully.

2008 toyota tacoma whistling noise


I don't know how loud the noise is, but its weird that you mention 50 mph. At that speed or above you are keep a constant rpm level. I say this because it might just be your air box loose and the sound of the intake air is making it. A 2008 truck should not have any major problem. Sometimes an alternator will sing or whine but never heard anyone say something is whistling. One other thing is sometimes for some reason ive heard a noise like that coming from the speakers of my car that goes up and down with the speed of the motor, but that was when I was tinkering with speakers and sub outs and amps. Thats all I can think of.

Loud whistling noise when travelling at higher speeds (ie above 50mph)


I had a problem with a whistling car after 50 mph and it turned out to be the front window gasket. I put silicone on the trim and problem solved.
