You won't find a simple, definitive "here's the exact location" answer without access to a repair manual specific to that year and engine. The location varies slightly even between years and specific engine variations.
To find them, you'll need:
* A repair manual: This is the best resource. A Haynes or Chilton manual for your specific vehicle will show diagrams and describe locations.
* A good look at the engine block: Once you have the vehicle up on jack stands (safely!), clean the engine bay as best as you can to improve visibility. Look carefully at the sides and bottom of the engine block for the circular metal plugs, often slightly recessed. They are typically made of metal and may have a slight lip or be flush with the block.
Warning: Locating and replacing freeze plugs requires some mechanical aptitude and the right tools. If you're not comfortable working on engines, take it to a qualified mechanic. Incorrectly removing or replacing them can cause significant engine damage.
