The first thing to do is to buy a new swamp cooler water pump to replace the old one.
They can be bought at most any hardware store or even online on Amazon.

When buying a new pump it is best to match up the Horsepower (HP) to the old one.
Even though most swamp cooler pumps are the same it is best to make sure the correct HP sized pump for your unit.
Most all water pumps for a evaporative cooler will be 110/115 Volts. There are some rare exceptions, so be sure the voltage matches your system also.
Swamp coolers will also have a build up of dirt and other debris that should be cleaned out. If it is not cleaned out it can clog up the new pump and possibly damage it.
