Freeze plugs are typically located in the engine block, usually on the sides and sometimes on the bottom. They're not always easy to see without removing some components.
To find them, you'll need to:
1. Identify your engine: Check the engine compartment for an ID tag or your vehicle's documentation to determine the specific engine type (e.g., 305 cubic inch V8, 350 cubic inch V8). This will help you find a diagram.
2. Consult a repair manual: A Haynes or Chilton repair manual specific to your year and model Caprice will have diagrams showing the location of the freeze plugs. These diagrams are invaluable.
3. Use online resources: Search online for "1985 Chevrolet Caprice [engine type] freeze plug location diagram". Websites like forums dedicated to classic Chevrolets might have helpful images or discussions.
Without knowing the specific engine, I cannot provide precise locations. Attempting to locate them without a proper diagram risks damage to the engine. Use caution when working on your engine.
