Ever since mid summer I have had problems with my cooling system leaking, at first it was due to some bad hoses, instead of replacing the bad hoses I replaced all the hoses, thermostat, and even the thermostat housing due to having a crack in it, all coolant sensors, ect. a few weeks ago I was heading back from work went home for a few and then left for a concert and as pulling out noticed a small puddle on the ground, I realized I forgot to replace the small hose at the bottom of the thermostat housing, which had just recently got a crack in it, replaced that, no more leaks. a week later notice another small puddle on the ground, checked for leaks and loose hoses but didnt appear to have any. after that it has not leaked since. I know I dont have a BHG due to having none of the symptoms. Is there something im missing that every month or so I'll have a small puddle?
