Will an engine from a 98 explorer fit 97?

A 98 Explorer engine *might* fit a 97 Explorer, but it's not guaranteed. While many parts are interchangeable between those model years, there could be subtle differences in mounting points, wiring harnesses, or even the engine itself (depending on the specific engine options available for each year).

To be certain, you need to:

* Verify the exact engine codes: The engine code (found on a tag on the engine itself) is crucial. Even if both Explorers are nominally the same engine size (e.g., 4.0L), there could be revisions between the 97 and 98 model years that affect compatibility.

* Compare parts diagrams: Use online parts diagrams (like those from a reputable auto parts store) to compare the engines and their related components. Look closely at the mounting brackets, sensors, and overall layout.

Without checking these details, swapping the engine could lead to significant issues, including mismatched parts, improper fitment, and electrical problems. It's always best to be thorough before undertaking such a swap.
