The pulley is different. ATX and MTX have different belt drives. The ATX only uses one 6 rib belt. Where the MTX has a 6 rib belt and a 4 rib belt.My step dad looked into it he found that the 3.0 and 3.2 have the same part number
Why are the part numbers the same my step dad works at Napa and the part numbers are the same. Maybe the pulleys arent? I dont know for sure but he said the the pumps are interchangeable. Maybe the pulleys can be swapped?The pulley is different. ATX and MTX have different belt drives. The ATX only uses one 6 rib belt. Where the MTX has a 6 rib belt and a 4 rib belt.
