my st200 has developed a noise and it sounds like it is coming from a pulley. if you look from the drivers side of the engine its the pulley at the top inbetween the V. what does this pulley drive?

the car has recently had a new alternator, idler pulley, belt tensioner and belt, so these parts should be good.

any help would be good

cheers Matthew

 

What kind of noise? A ticking, or a 'thrumming'?

 

That pulley is the PAS pump

 

hope it's not the timing chain tensioner thats noisey, my st200 started making a noise, a few miles later the pistons exited the block!!!

the engine blew 7 miles after I sold it pmsl!!

Mine does the same. Check PAS fluid level. Mine was v low. Topped up. No more noise. Job jobbed. (temporarily lol!)

 

it sounds more like a worn out thrumming/squeaking noise, i'll check the fluid levels,

cheers for the help

Take the aux belt off and see if the noise is still there.

 

As said top pulley is PAS.
Mine has a soft ticking noise when hot from that area.
I don't think it is the auxilary belt, but can't make out if it is the chains or chain tensioner. Put it this way i ain't taking the whole bloody engine apart to look at the chains. Major major job.
Unfortunately the car will be driven until it dies .

 

mine does it as soon as the engine is running,so temp is not affecting it,definitley sounds like a pulley issue,its going in the garage tomorrow so hopefully will find out what it is

cheers fo rthe advice

i looked at a mondeo a few months back; weird kinda noise, turned out to be head gasket!
