Guys,
I want to look for a pulley on Ebay.co.uk but I don't know it's name. It's an expensive one, it drives a belt that moves the power
steering and alternator. I've searched for "vauxhall frontera pulley" and I got many results for "crankshaft pulleys"? Is
that what I'm looking for or maybe that's the main timing pulley?
Thanks a lot.
Auxiliary belt, or auxiliary pulley. Can also be referred to as the serpentine belt.
It could be the crankshaft pulley - this is the large pulley at the bottom of the engine.
Havent you got a man-uel?

The car is in a garage who is asking lots for a repair. Tomorrow I'll be able to confirm with them if the pulley is bolted to the crankshaft and
I will ask them the part number, but it really looks like it's this "crankshaft pulley" on the search results, only they "buy
now" price is half of what they've said over the phone today 
No operation "manuel"
What on earth has gone wrong that it needs a new pulley?
I can't think of much that would break that without needing a lot of other stuff... like a whole new engine!
It's not a tensioner pulley that's gone is it? These are a serviceable part.
Cheers,
James
Only thing that usually goes WRONG with a pulley is that it was slack and the Key way has worn.
If it is an Idler Pulley like the on Vaxhall Vetcra's etc. These are advised to be changed dooing Cam (timing) belt changes.
What is up with the car as we may be able to diagnose?
Thanks for all the help, guys. I've been in the garage today and now I know the story. This engine (Vauxhall's 2.2 DTI) has one belt only
as the the valve train is chain driven internally. It's got this "crankshaft pulley" for this belt to move a few different things. The
pulley is very special and pretty complex for a pulley (I had it in my hand), it's got a plate, a ring, and some intermediate piece that's
not made of steel or metal, but some kind of hard rubber? That's why it's so expensive. I've missed the opportunity to buy the
aftermarket part from Ebay, when I got there, the new pulley was in place and the belt was being placed 
Torsional vibration damper / harmonic balancer type pulley
Out of curiosity, do you know what material actually is that middle bit made of?

If it is a harmonic pulley, and they applied the wrong type of pulley puller then it was their fault as most likely itīs `f+++ed....

Not the case, the owner of this car confirmed that the pulley broke while driving. She could not steer so she had a look to the engine and saw this pulley in two pieces.
...But I thought the same until she told me that.

They could fail also if one of the accessories seizes suddenly....
