NISSAN QUEST HEATER PROBLEM

1996 Nissan Quest • 230,000 miles

The Heater Core on a 1996 Nissan Quest XE must be broken because there is water leaking into the interior of the van. The Core was bought but no hoses are included. What exactly is fully needed to properly replace the heater core? They also tell me that there are Two Heater cores?
