5.7 hemi daytona-have coolant leak ONLY when vehicle sets overnight. In morning there is coolant small amount maybe 1/2 cup on garage floor. I also will notice coolant dripping down timing cover, AS WELL as coolant is pooled on top of water pump housing in the small valleys of housing. Water pump and Thermostat were replaced last year after original water pump failed. coolant is NOT coming from water pump bottom "weep"hole. Hoses are not leaking. I run the vehicle for 45 minutes in driveway-no leaks-pak in garage next morning same coolant on floor and traces in same places, front of timing cover and around water pump. If I drive the vehicle at that point heat fro engine dries it and no leaks. I am wondering if this is caused by my radiator needing to be replaced, however this is simply an educated guess.

 

Possible leak from radiator "spraying" onto engine... maybe?
