* On the engine block: These are the most common locations. You'll find them on the sides of the block, often near the bottom, and sometimes on the top near the cylinder head. Their exact location can vary slightly depending on the casting of the specific engine block.
* In the intake manifold: While less common, some freeze plugs might be located within the intake manifold itself.
You won't be able to see all of them without removing various components. To find them all, you'd ideally need a workshop manual specific to your 1989 Ford Bronco 351W. These manuals provide detailed diagrams showing the locations of all the freeze plugs.
Why is this important? Knowing the locations is crucial if a freeze plug fails (a common problem in colder climates), as you'll need to repair it. Trying to locate and replace them without a reference can be very difficult.
