I've recently been having problems with throwing my belt out here in the boonies of Buckeye, AZ, after shopping around I found that Goodyear makes a serpentine belt conversion kit (part #49215K) Basically what it does is replace the belt with a double sided grooved belt, and replace the tensioner and idler puley with groved pulleys. The only thing I'm worried about is the fact that this kit does not come with a water pump pulley that is grooved, and after looking around I can't find a grooved water pump pulley. My concern is that if I run the double groved belt that the smooth pulley of the water pump with distort the grooves in the belt or slip on the pulley, losing performance from the water pump (which CAN NOT happen with the AZ summer coming up). So, will I be safe running this setup with the smooth pulley? or better yet is there a grooved water pump pulley from another chrysler vehicle that I could just bolt on to my water pump?
