1994 suburban 350 catastrophic coolant failure!
so i got stuck in about 4 feet of snow out in the middle of wyoming friday night and had to spend the night, i tried to keep it running as much as possible but i didnt have enough fuel. when i finally got it pulled out the next day it was running fine till i started to get on it. i had a leak out of my lower radiator hose. my thermostat had gone out. i replaced the thermostat, the coolant, and the hose and it ran just fine heat worked thermostat opened and everything without problems i drove it again tonight and it ran well untill i steped on it and when i looked behind me there was a large cloud of smoke, i pulled over and it was steaming (not overheated) and it was gushing my brand new coolant onto the ground. upon further inspection i noticed it was coming out from the block underneath the exhaust manifold and behind the engine mount. what could it be? freeze plug? i didnt hear a bang so i dont think im missing part of my block or anything but im completely stumped. i removed the tire and fenderwell and im in the process of taking the exhaust manifold off tomorow and trying to figure out why this is being such a pain.
