Review on 🚗 Enhance Your Vehicle's Performance with the Gates 37010P Alternator Pulley Kit by Justin Hill

Great dealer alternative, matches my 98 Jetta engine code AHU exactly, this car had a starting problem which I believe was caused by the crank sprocket falling out due to the durable alternator pulley over time. Transmission of the impact through a serpentine belt. Luckily the grip nose was fine. Had this pulley been installed on this vehicle from day one and replaced at regular intervals or whenever the owner had noticed excessive belt vibration, the crankshaft sprocket problem could have been avoided. If you have a 96-97 Passat TDI with engine code 1z or a 1996-1998.5 Jetta mk3 with engine code AHU you will need this.
