Help identifying / buying water pump pulley bolts

[mathcrimes]

hello,


i've been having the worst time trying to figure out exactly what type of bolts are used for my water pump pulley and how to order them. there is no mounting kit for my water pump pulley and i keep getting different answers about what the correct bolt is.



i'm trying to figure out what the bolt needed is, where to order it, and how to look up this type of info for the future.



the car is a 1998 mercedes-benz E320 sedan. thank you if you can help!!

For a 1998 E320, the water pump pulley bolts are likely M6x16mm or M6x20mm—confirm with a parts diagram or dealer. Use the VIN for accurate lookups, and check sites like FCP Euro or ******** to order. Good luck!
