Default Whisteling noise on cold start up

hi all ,new to the forum and i have been searching every where for this kind of issue (I THINK SOMETIMES ITS IN THE HEADING)
It has probably been covered but thought i would ask anyway ,
every morning i start up the pajero i get this whisteling noise (sound like a steam whistle like a train)
whirring sound .
Its not the vacuum hoses tested them ,its comming from the front of the engine .

i am leaning to believe it is one or two of the idler pulllies as when i spray them with so WD40 it stops for a few seconds then returns .once the engine is warm and has run for a bit its gone?


then returns the next cold morning on start.

have ordered the pullies and a new belt to fit what would be the next thing to look at .
only had the car 2 weeks .oh and ( I AM THE WARRANTY )



any advice would be nice cheers

I had a similar noise that I described as a whistle on a TD Santa Fe a few years back and it was the exhaust manifold gasket, only takes a tiny fault / crack or the like to create a whistle when cold and once it was hot that small air passage was closed due to expansion. Noise gone once replaced.

Perhaps check the tension on the belts before you take them off and maybe a squirt of 'Belt Grip'

I'm not sure the likes of WD40 is a good thing on belts.......just my thinking.....

I've known of a crook alternator producing a high pitched whistle. Short brushes or faulty diode(s).

High charge rate (after startup) or heavy electrical load made the whistling noise more pronounced.
