I have a 1992 gmc sierra 2500. Just got home from my shop and noticed coolant smell as I got home. It isn't a slow leak and haven't been having any issues at all. But about 1/2 a block away from home it dumped the coolant all over the road and driveway. I just thought it blew a radiator hose, especially with the dump of coolant. But the coolant came from the back part of the engine, all around the radiator is dry and hoses aren't leaking at all. Just not sure where to start as the coolant kind of went everywhere back there. when I fill the radiator it is dripping down right at the starter, and it just dribbles out freely as i add fluid.
