SL55/63/65/R230 AMG: Drive belt job for SL65
For my 2008 SL65 with 93k miles I was recommended to change the drive belt sooner rather than later. The parts I found are:
1 Serpertine Belt 24.96 x 2335mm A0149973792
1 Drive belt idler pulley (grooved) A0002020719
2 Drive belt idler pulley (smooth) A1372020119
1 Serpentine belt tensioner pulley A1372000270
Is this correct? Because I found another serpentine belt A0139977192 that I don't know what's for but it wasn't on the estimate given to me.
Thanks,
Leo
