Where is the oil cooler located on a Ford f-250 diesel?

The location of the oil cooler on a Ford F-250 diesel depends on the year and engine. There isn't one single location. It's generally integrated into the engine block or mounted near the front of the engine, often near or as part of the radiator assembly. To find it precisely, you'll need to:

* Consult your owner's manual: This is the best resource. The manual will have diagrams showing the location of all major components.

* Use a repair manual specific to your year and engine: These manuals have detailed diagrams and often show the oil cooler's exact placement.

* Look online for a diagram specific to your truck: Search for "[your year] Ford F-250 [your engine] oil cooler location" on Google Images or YouTube. You'll likely find pictures and videos showing its placement.

Without knowing the year and engine of your F-250, I cannot give a more precise answer.
