To be absolutely sure, you should:
* Consult a repair manual specific to your 1997 Ford Ranger's engine. This will provide diagrams and precise locations.
* Use a parts diagram available online. Many auto parts websites let you search by vehicle year, make, model, and engine to view diagrams showing parts locations.
Visually inspecting your engine after consulting these resources will confirm its position. Remember to disconnect the negative battery cable before working near the engine.
