When should i change timimg chain on 1999 Tacoma?

The timing chain on a 1999 Toyota Tacoma is designed to last the life of the engine, but it’s a good idea to inspect it if you notice any symptoms of wear or noise, such as rattling sounds from the engine. Regular maintenance, including checking the tensioner and guides, should be part of your routine. If you experience engine misfires or poor performance, it may also indicate that the timing chain needs attention. Always refer to your owner's manual for specific maintenance intervals and recommendations.
