Chevy 350 Expansion/Freeze Plugs

Q. Question: I have a coolant leak in the lower back of my Chevy 350 engine. I am trying to locate freeze plugs in that area. Do you have or can you direct me to a diagram of freeze plug locations on Chevy block?


Chevy 350 Expansion/Freeze Plugs

A. All small block V-8's have freeze plugs in the rear of the engine where the transmission bolts up. There are also two on each side of the block near the motor mounts. A pressure tester hooked up and a bright flashlight should be a great help.
