Need some help diagnosing coolant leak in my 5.3L Sierra Found some coolant laying in the driveway this afternoon after getting it washed. Seems to be dripping down from the drivers side wheel well. The mud flaps behind the front wheels had frozen coolant isicles hanging down too.
I couldn't pinpoint the leak. Just found it strange where it was leaking though. It seems to be on the side of the block or possibly in the back of it. It's not overheating and the resivoir seems to be pretty full. I figured if it was the water pump it would be leaking towards the front of the motor. It's a 2010 5.3 Sierra with 53k miles. Looking for some help or input that could lead me in the right direction. Thanks.
