Where are the freeze plugs in 1998 Chevy 2500 pickup with a 350?

The freeze plugs (also called core plugs) in a 1998 Chevy 2500 pickup with a 350ci engine are located on the engine block itself. There isn't a single, easy-to-describe location, as they're distributed around the block. They're typically found in the following general areas:

* Underneath the engine: This is the most common location for several freeze plugs. Accessing these requires working from underneath the truck.

* Around the cylinder walls (sides of the block): These are often less accessible, potentially requiring partial disassembly of other components to reach.

* At the rear of the block: You'll likely find one or more freeze plugs near the back of the engine block.

You won't be able to see all of them without removing some components. A repair manual specific to your 1998 Chevy 2500 with the 350 engine is your best resource. It will have diagrams showing the exact locations and sizes of the freeze plugs. A Haynes or Chilton manual would be a good investment if you plan on doing any engine work.

Without a visual reference from a repair manual, attempting to locate them blindly could lead to damage or missed plugs.
