Good evening y’all,

Hope my fellow Silverado owners are doing well. Just chiming in with a post here in order to obtain some assistance in the diagnosis of what I believe is a small coolant leak location on my 2005 Silverado with the 5.3 Vortec @70K miles. I believe it’s a seal gone bad caused by drastic weather changes moving us south of 35 degrees here in north Texas over the last few weeks. I took some photos, one from the top of the engine bay, and one below. I’ve circled the wet areas in red. Any further clarification here on where my leak is originating from would be great. Only information I can give is that looks to be in the area near the A/C compressor. Maybe below it? Again, any help here would be great. As far as what’s causing this leak and the part I would need to purchase to fix. Thanks!

- Brenden

Looks like my 2001 suburban water pump gasket failure on the passenger side.
It's above the ac compressor.
