If your water pump is leaking, check the hoses around the pump first for any sign of leaking. And if you are planning to tackle the water pump change your thermostat at the same time. when installing the water pump try not pinch the O rings(or replace) from the coolant pipes. Takes your time (patience) with the water pump gasket because it could be a pain in A$$! The thermostat install is a cake walk. Goodluck
