just took the car out for a 20 minute drive and while backing up to fix my spot i saw drips. shut the car off and saw drips. I then pipped the hood and looked around and noticed coolant on the lower raciator hose. Hmm. started queezing the hose and heard a clicking noise. then moved my hand to where the thermostat housing is and felt wetness there. Would that clicking be my thermostat housing moving because it has a crack in it? The car is going back into the shop monday for a coolant leak. The guy said it was a lose hose clamp, I think its my thermostat hosuing. Also I noticed the lower radiator hose wasnt hot compared to the upper one. Is this because the lower hose comes out of the raditor and has cool water in it?
