What is a Chassis number and why do I need it to figure out what parts fit my Volvo?
Volvo is notorious for changing engine parts in the middle of production Model Years. When they do this, they make a notation in their parts catalog stating what engine serial number range or chassis number range a product fits.
The Chassis number is the last six digits of your Vehicle Identification Number (VIN) with any leading zeros removed. (i.e. 000123 = 123)
