Mazda Millenia Drive Belt Replacement Q. Hi, Do you have a schematic of how the two drive belts fit in a 1999 Mazda Millenia 2.3 liter V-6? Do you also have any tips on replacing these belts? Is it just a question of loosening the belt tensioner and then pulling the belts off, and reversing those steps to replace? Thanks in advance, Andrew

A. Here's how to do it! No special tricks to it.
