    Help!!!

    my yukon is leaking coolant very badly and ive replaced the thermostat and seal and waterpump gaskets in the past two days an it has not helped. i inspected the pump and found no visible cracks or anything out of the ordinary. its deff leaking on the motor side of the system the belts are getting soaked and i can get under and see it running off the bottom of the water pump but cannot find the origin.i know if i take it to a shop they will rape me in parts and labor but i can afford to keep buying gallon after gallon of antifrezze. when it drips its more on the passengerside of the motor but i believe thats from where its running across the bottom of the pump.

    The water pump is probably bad. Mine leaked from the weep hole on the back of the pump. You cant see it when its bolted on the motor but its most likely coming from there. You spend 80-100 bucks on a new pump and see if that works, if nothing else you have a new pump. You shoulda replaced the pump when you replaced the gaskets

    Wait!?! You work on your truck? lol... J/K man. Probably bad bearings in the pump.
