I purchased all new belts last summer. I had the same concern about buying new old stock belts. So I tried to source belts that are equivalent common use. Some luck. The oil belt is probably made by Continental-ContiTech and is available thru a variety of suppliers. Here are the results of my research:
4G7Z-6B651-AA | Belt, Oil Pump - Ford | 83.00 |
Y-720 | Belt, Oil Pump - Goodyear | |
45PL36 | Belt, Oil Pump - From Grainger | 46.00 |
20038721 | Belt, Oil Pump - Continental | |
Y-720 SIlentSync | Belt, Oil Pump - ContiTech | 36.00 |
4G7Z-8620-AA | Belt, Supercharger | 48.00 |
4G7Z-8620-BA | Belt, Main/Alternator | 29.00 |
Dayco 5100883 | Belt, Supercharger | 50.00 |
Dayco 5060923 | Belt, Main/Alternator | 32.00 |
I ended up buying all three from my local dealer who sourced them from Ford. I could not determine if the belts from other suppliers were for sure correct (probably were), but the prices were better from Ford, except the oil pump belt. The Y-720 SilentSync seems to be available from a variety of suppliers. I figured that I would rather take my chances with Ford. The oil belt did have a date on the package of 2010, remember this was sourced from Ford last summer. The other belts have recent dates on the package. I have attached pics of my old and new belts, the new ones are the brighter white print. Keep us posted on what you find.
