Do you have to change the timing belt on 2000 Ford Ranger 2.5 L at 60000 if it is running fine?

No, the recommended timing belt replacement interval for a 2000 Ford Ranger 2.5L is generally 100,000 miles (160,000 km), not 60,000 miles. While it's *running fine* now doesn't mean the belt won't fail unexpectedly after 60,000 miles. A catastrophic timing belt failure can cause significant engine damage.

Therefore, changing it at 60,000 miles is unnecessary and premature, but waiting until closer to 100,000 miles (or even slightly exceeding it, depending on driving conditions and maintenance history) is risky. Check your owner's manual for the exact recommended interval specified by Ford for your specific vehicle. It's always best to err on the side of caution when it comes to timing belts.
