The kit was complete, it included everything needed for a complete timing belt replacement plus all pulleys and a complete water pump with housing. The complete set of the water pump with case is important. When I last changed the timing belt and water pump on this car, as usual, I only replaced the water pump without the housing. I finished this job when a leak started to flow between the water pump and the old housing. Hopefully a handpicked and pre-assembled factory kit will prevent this from happening again. It didn't cost much more, it was easier to make and I have more peace of mind.
