The timing chain on a 2007 Nissan Altima 2.5 is designed to last the lifetime of the engine, typically requiring no regular servicing or replacement under normal driving conditions. However, it's important to maintain proper engine oil levels and change the oil regularly to ensure the timing chain functions smoothly. If you notice unusual noises or performance issues, it's advisable to have it inspected by a mechanic. Regular maintenance can help prevent potential issues down the line.
If the engine has a timing belt, it should be changed around the 150K mark. If there is a timing chain, it does not have to be changed unless it is damaged.
