When do you replace timing chain on 2012 Ford Escape?

The timing chain on a 2012 Ford Escape is designed to last the life of the engine, typically requiring replacement only if there are signs of wear or failure, such as unusual noises, engine misfires, or oil leaks. However, it's a good practice to inspect it during routine maintenance, especially around 100,000 miles. If you're experiencing any symptoms, consult a mechanic for a thorough evaluation.
