[lifelicksballs]

okay, i recently bought a waterpump in hopes of replacing the old one but i noticed i needed to take out the crank pulley in order to take out the lower timing belt so does anyone know what size socket i need or something and should i just use a pipe to pull it out cuz it looks pretty rusted on tehre

and another thing does anyone know the size of the sohc ka maf for the k&n pod type air filter?

thanks alot
