I Have a 94 Starwagon SH 2.4L, I have recently been having troubles with the alternator in specific belts the last 3 months it has broken 2 belts and stretched 1. I was wondering what is the correct size for the belt I Have retained 2, 1 'DAYCO Top Cog Gold Label 13A1005' which stretched or was never the right size to start with and 1 'DAYCO 13A1000 12.5 x 1000' which snapped. Both have been fitted by auto electricians. Is there something else that could be causing the belts to fail, any ideas would be great.
