My 2006 Yukon XL Denali and 6.0L was leaking coolant even

Customer Question

My 2006 Yukon XL Denali and 6.0L was leaking coolant even when engine was off. I replaced the water pump and serpentine belt and it is not leaking any more, but now it won't turn over. I have a new, fully charged battery. Lights and other electronics turn on when key is turned and a single click is heard. Any thoughts? Starter? Solenoid? Other things? Thanks, Brant
