I have just serviced the engine (MD2020D) on my 2004 B32 using filters, etc found in the boats tool chest. These items came with the boat when I bought her 2 years ago.
I now need to replace the items I have used and have looked at a couple of websites for genuine Volvo parts.
Regarding the oil filter the old one I removed during the service was identical to the one in the tool box. Serial 3840525.
When I search for the correct filter for my engine this serial number is not mentioned as being suitable for my engine, but is listed against other newer engines.
The filter listed for my engine is either 21549544 or 861473.
I am having the same problem with the fan belt as well. The one I put on the engine is 973534. the one listed is the same number but with "R" after the numbers.
I have had no problem with the impeller or fuel filters.
Has anyone had similar problems sourcing the correct parts?
PS: I have been looking at Volspec, Keypart and Asap Supplies.
