* One near the distributor: This is typically the larger of the two and located on the front of the block, somewhat near the distributor (if your truck has a distributor, as some 1997 models did, and some might have coil-on-plug ignition).
* One lower down and to the side: This is usually smaller and situated lower on the front of the block, often towards one side (either passenger or driver's side). It might be somewhat obscured by other components.
Important Note: Without a visual reference (like a workshop manual specific to your engine's casting number), pinpointing the exact location is difficult. A service manual for your specific year and engine will show diagrams and precisely locate these plugs. Incorrectly removing freeze plugs can cause significant damage, so a visual guide is highly recommended.
