When to replace the timing belt?

I just bought a 2012 Tundra Rock Warrior with 79,000 miles. I would like to know when I should have the timing belt replaced. Also how would I know if it had already been done?

 

If it is a 5.7l then you have a timing chain, not a belt.

 

OK when should it be done, and how do I know if it's been done?

 

Timing chains are not routine maintenance. Most last 250-300k miles or much more. Most never get changed; on any vehicle. They are typically changed on major rebuilds but not on a certain requency.

 

Thank you very much.

 

You should try to get an owners/shop manual for your Tundra so you can have a reference for all maintenance items and when they should be done.
