So I can't figure out where this leakis coming from please help! I replaced the o-ring on the thermostat today after I was done I put everything back on tightened it all up then filled my coolant reservoir back up and out of no where all my coolant comes gushing out the bottom I can't find where it's Coming from. I don't really know where to look besides the obvious can any one help me with pictures?
Easiest to check is the lower radiator hose and the radiator drain **** which is on the bottom passenger side.Worst case is the it's pouring out of the water pump which is behind those covers in front of the engine. You should keep this in the LS forum since it is vehicle specific. You just have to be patient and wait for the responses to come.
