    Hello: I am a new member & have a 2006 Tundra with a 4.7 engine. What is the correct time to change a timing belt? My owner's manual says 90,000 miles. My Tundra has only 49,000 miles on it. Should I wait until 90,000 miles or should be changed now with this low mileage? It is used for light duty & is in great shape. What are your thoughts? Thanks John Larson - Washington State

    You will be safe to wait until the 90,000 miles. I have a 2007 with the same 4.7 engine. I changed it at 123,000. I thought I was going to get a new one, but stayed with the one I have now. I have changed the timing belt twice already and still runs like new. It has 223,00 miles on it already. No issues.

    I've know guys that had changed the timing belt for the first time at 140,000 with no problems either, but then, its a risk you take.

    I'd say it's good to go for a bit. Did mine on my 2000 at 110k, but I also had a water pump that was starting to leak. Save yourself the trouble and do em all at once

    I know this thread is a bit old but you could easily wait. I recently bought a 2007 Tundra 4.7 with 44k miles and I researched like crazy about the timing belt and if it degrades over time regardless of mileage. Dealership told me to go by mileage but an 11 year old belt just did not sit right with me. Had a friend of mine replace it for $400 and told him to keep the old belt because I wanted to inspect it. Upon inspection, there were absolutely zero cracks or anything on the belt. And that’s with me bending it over and pinching it together really tight to expose any small cracks that you wouldn’t normally see. The inside of the timing belts (the teeth that actually go on your drive and valve pulleys) is actually not rubber. It seems to be constructed of a tightly woven fiber that is extremely durable. I’ll post some pictures later on.

    Long story short, people will tell you to go ahead and replace it anyways because it’s not worth the risk of it breaking but my 11 year old belt with 44k miles on it literally looked brand new with almost no signs of any wear at all. The paint markings on the back side of the belt was even still fully there. Don’t waste $500-1000 doing this repair prematurely. Your belt with 49k miles, even though it’s 12 years old, will likely last you another 50-70k Miles if you wanted to push it. Personally, if it were me knowing what I know now, I would change it out when I hit 90k miles and not think twice about it.

    Thanks for your reply. I don't think I will ever wear out this truck. I put about 3,000 miles on the truck each year. I used to drive it to work on a daily basis, but now I am retired & the truck gets used once or twice a week. I just replaced the original tires last year, because of the age of the tires. They still had good tread on them, but it was time. Thanks again for your reply.

    No problem. And that sounds good. One other thing I will say is to keep a check on any rust that develops on the frame. Depending on where you live, this may not ever become a problem but there is a TSB in case it ever does. Other than that, just change out the oil regularly and you won’t have any issues with it. These are the most reliable gasoline engines ever built, without question. Enjoy it!
