However, generally, freeze plugs are found on the engine block, usually on the sides, under the engine, and sometimes on the top. They are typically cylindrical and relatively small.
To find them, you'll need to:
* Consult a repair manual specific to your 1994 Ford Ranger's engine. This is the best way to get a precise location for each freeze plug. A Haynes or Chilton manual will show diagrams.
* Look underneath the engine. Many are located on the lower part of the engine block.
* Carefully inspect the engine block. They are usually recessed slightly into the block.
Warning: Locating and replacing freeze plugs can be a messy and challenging job. If you are not comfortable working on cars, it's best to take your vehicle to a qualified mechanic.
