I am about to collect a Suzuki X90 4X4 that has done 102,000 miles. It drives very sweetly but it does not have a service history. The current owner thinks he had it replaced about 30,000 miles ago so, one of the first jobs I want to do is replace the belt and the tensioning arm. There appears to be a significant price difference between buying genuine Suzuki parts and aftermarket parts. As I have no experience with Suzukies I would appreciate advice on the quality and reliability of these aftermarket parts and any recommendations as to which ones to use or avoid. Also, if there is anything else I should be changing.
