Hi:
As far as what is needed, you will need a new pump, which should come with a new gasket. Additionally, you will need to drain the old coolant, so new coolant is needed as well.
This is a great time to replace the radiator hoses if needed. Inspect them to see of there is evidence of wear or damage.
To help, I attached the directions below for replacing one on this vehicle. Also, here is a link that you may also find helpful.

Let me know if this helps.
Take care,
Joe
