2007 Tahoe 5.3 Coolant leak
 

Late Today I noticed anti-freeze dripping from that plastic fitting near the thermostat housing (above the a/c compressor).At least I think that is where it is coming from.It is the fitting where the overflow tank lower hose goes to.Can somebody name that fitting and how hard is it to change? I'm tied up tomorrow and can't get over to the dealership.Thanks.

Post photos: good, clear ones. Maybe use software to point an arrow at the place you think is leaking.

Thanks Cusser, unfortunately I don't have a picture hosting site.I did find the part.It's a 2 piece heater hose that goes to the heater core and the supply line from the coolant reservoir.The plastic angled "T" fitting has a crack in it.It comes as a one piece assembly.
