Thanks for what to look for I was thinking that maybe it was something to do with the hose just haven't been able to look at it. The hose that connects from the bottom of the reservoir tank is that a dealer part if so what do they call it and also the y split I might as well change them all. The y split and the tube from the bottom of the reservoir what'* the other tube connection to. And one more thing I changed my thermostat a while back and the clamp hat u need to use pliers my mechanic changed it for the clamp you use a flat head to tighten could that cause a leak since it'* a diff clamp it looks like it'* on good but I don't no what else to do with this truck all I could do is take pics and post to see what response I can get

Different clamp used to tighten around thermostat can that cause a slow leak or is thus clamp good enough
