Help with coolant leak
Hello. My 2008 (z51, 85000 miles) is leaking coolant. Not overheating. Just leaking below the car. I have a lift but can't really see exactly where the leak is from.
It is not the radiator or any hoses I can see.
From below you can see coolant dripping from the bottom of the leaf spring. At close look, fluid is dripping from above the right front of the engine block down to the leaf spring.
I can see nothing from the top. I will remove the air cleaner assy next to get a better look. But first I figured I'd ask you guys for what you think it may be.
Could it be the water pump?

I did it in my driveway with the front end on jack stands, but it was not a fun job and I'd pay someone to do it for me if it's only a couple hours of labor.
I was never able to definitively say where the leak was coming from. I think it was coming from the passenger side of the water pump because the gasket had some black material on it when I got it out, which tells me it didn't have a perfect seal.
This is the replacement I ordered, comes with gaskets:
I bought new upper and lower rad hoses to replace while I was at it, but honestly, they seemed fine. Good peace of mind but was an extra almost $100.
