The o-ring is about 2 bucks, the idler pulley is about 70, belt is about 90..price will vary from dealer mark-up

Just make sure the o-ring is only thing leaking and not the Y-joint seal (where the head/timing cover/engine block all meet together.) look at the top-outward most 8mm head bolt of the timing cover for both banks, if they're soaked in engine oil..Y-joint seal is leaking also, replacing only the belt will be just a temp solution, noise will come back due to contamination of oil from the leaking Y-joint seal

If engine squeaked on a cold start and noise went away when warm...9/10 the engine still had the old style idler pulley, fix would be the new idler pulley (standard on 4.7L) and new belt for the new spec pulley..

If the belt squeaked when cold..and did not go away when warm, either belt has coolant or engine oil on it..trace the leak and fix..then replace the belt and idler pulley if it's stil lthe old style...9/10 if this was the case, air/oil seperater was leaking from the o-ring(AD23-3B9623-AA), replace o-ring to delete the concern and wash engine with belt off..dry everything and then fit the new belt and new pulley

Newer belt for newer pulley: 9G33-8620-AA
Newer idler pulley: 9G33-19A216-AA

Is it same for DB9 ? I have 2009 DB9, i am about to replace the belt and pulley, do I replace it with grooved one?

No idea who makes an aftermarket substitute. V12 has 2x smooth pulleys + 1x v-grooved + 1x tensioner. The pulleys are around 30usd each, tensioner in range of 100usd and belt around 80usd. Whether it be a 2001 V12 Vanquish or 2009 V12 DB9, same parts..

However, there's no reason change the pulleys on a V12 unless faulty, just change the belt...
