The truck is showing high oil temperature, thermostats were replaced and temperature sensor but the problem persists, do I have to replace the oil cooler of the engine?


RESPONSE

The engines cooling system is not overheating, the engines oil is. If the engine temperature is good, then that part of the system is fine.  It is possible for the oil cooler to be clogged or obstructed.  The most common cause for overheating would be from a Snow Plow blade blocking the air flow.

Use Motorcraft SAE 5W-20 Premium Synthetic Blend Motor Oil.

Engine coolant provides freeze protection, boil protection, cooling efficiency and corrosion protection to the engine and cooling components. In order to obtain these protections, the engine coolant must be maintained at the correct concentration and fluid level in the degas bottle.

When adding engine coolant, use a 50/50 mixture of engine coolant and distilled water.
