Coolant leak

[Mr_Gonzalez]

I been having a coolant leak for a while now
I would have to put a gallon pre mix coolant every 3 months and then it got to be gallon for every month
So I changed all the hoses and then still leaking
So bought a new radiator and I still been loosing coolant
Today I notice it dripping from motor
I could tell if it was coming from thermostat or water pump
It's on 2005 yukon xl denali 6.0 with 124xxx miles on the clock
Any help will be welcomed !!

It is most likely leaking from the weep hole on the water pump which indicates the water pump is bad.

How hard to replace ??

Super easy. Took me about an hour and a half, give or take.

Look for instructional videos on YouTube.
