Yes, its a 722.6. My problem is it started leaking several tablespoons a day and the pump is getting very loud. The car is currently at the dealership getting the seal replaced. It's going to be expensive, which is why I asked if I should do anything else while they have the car that far apart. In for a penny, in for a pound.
