Squeel with Key On

[gokeeper]

2005 Jeep Liberty CRD

New problem first thought it was the alternator then found it squeals horribly when not running. If you turn he key on it starts squealing horribly. I thought maby a fuelpump? but dont have any ideas sounds like its coming from the driver side near the egr. Any Ideas

I don't have a CRD but my Liberty squeals when the ambient temp is colder than -20'C. It only squeals for a second or to. In my case, it is a relay making the noise. Maybe you have a bad relay?

This is a real ear piercing squeal much louder than a relay thanks for he thought though doesn't go away even when you start the jeep.

Seams as though its the FCV anyone know of a how o to remove and replace also need to replace the EGR anyone have part numbers by chance? Thanks for your help.

Are you listening to ABBA or Spice Girls?

Just kidding.

It is a low pitch or high pitch? Does the engine temp affect it in anyway? Any other symptoms: lower mileage, less power, rotten egg smell?

 

[gokeeper]

very high pitched, Unplugged the FCV and it stopped. Happens whether the engine is running or not.

The gears in the FCV have gone bad or are stuck, try and clean it to see if that will help.
