You absolutely must check your owner's manual. This manual will specify the correct coolant type and concentration for your particular Ford diesel. The manual should also detail the recommended intervals for coolant changes.
Using the wrong coolant can severely damage your engine, leading to costly repairs. Don't guess – consult the manual.
If you don't have the owner's manual, you can:
* Check the Ford website: Use your VIN number to find your vehicle's specifications.
* Contact a Ford dealership: They can tell you the correct coolant based on your VIN.
* Check the coolant reservoir: Sometimes the recommended coolant type is printed on the reservoir itself (though this is not always reliable).
Never rely on generic advice online for this crucial maintenance task. Always prioritize the information provided by your vehicle's manufacturer.
