Coolant Leak

There's a coolant leak on the passenger side on my 05. I can't locate the source. There will be a puddle sometimes when I park but sometimes it won't leak anything. I'm confused as to what it is. I have egr cooler still intact but turned off. Truck has studs and deltas are fine. Anybody have this problem or know of a fix? Thank you

Hose clamp on heater core line or the water valve on the same line are a couple possibilities

Look at the blue hose on the egr cooler as well

heater core lines, check going through fire wall and front cover, check front cover (water pump), EGR re-route. Try and get your hands on a Coolant Pressure testing unit, pressurize the system and start searching.

Thanks for the info guys. I'll have time today to look at it and hopefully figure it out. I wanna do an egr del-ete and flush the coolant and replace with ELC so this looks like a good opportunity to
