major problem need help.

so theres antifreeze leaking under my motor mounts. i have a 1994 blazer lt. it has been leaking all night bcause ther is zero antifreeze in the radiator or resavwa. it was cold last night if that helps any. no idea waht can be happening please help.

sounds like a freeze plug they are located under exhaust manifold on each side of block one is behind starter also check all hose connections could be cold water leak due to clamp getting loose

Before you start replacing freeze plugs, you need to look closer at the leak.  You said you have coolant on your motor mount.  Look above the motor mount and see if you can find what exactly is leaking.
