my mechanic thinks i have a oil leak from the Biggest pulley(the centered one). These came with the car when i bought it. So I think he said he is going to replace the gasket? So he wanted me to ask you guys if he needs a Special tool to get the Pulley off? he works at a Dodge dealership so, are the pulley pullers universal or do i have to go rent a tool for him at Autozone or something?
