Question about 1993 Chevrolet S-10 Blazer
The motor has plugs called freeze plugs, but these are located on the back of the motor. There isn't much that can cause water to leak on the front of the motor, although a cracked block or cylinder head cam cause this. There also may be a small hose along the front that split and is causing your leak. Visually inspect all of your hoses - especially you heater core hoses which come off of the water pump. I suspect one of those has a split or a hole, which would cause that leak where you state. If you cannot find the split or hole, ADD a bottle of green food coloring to a gallon of water and shake to mix well. Get an inspection mirror ( a small mirror on a flexible handle or with a flex joint at the mirror ) and a flashlight, and slowly have someone pour in the water as you look with the mirror and flashlight for the leak point. Look on the back side of the hoses, as well as along the water pump base and all hose connections. Also feel ( squeeze ) all of your hoses - if any one feels soft enough you can squeeze it shut, I would replace it - it could collapse and cause the engine to overheat.
I hope this helps!!
