re: Old Toyota Tundra/sequoia, timing belt.

You people crack me up. You love how reliable the 4.7 is but you won’t spend $800 every 8-10 years to change the one thing that keeps it so dead reliable.

You can get a full kit for like $150. All you need to do is have the time, patience, and memory to do it yourself. Takes me about 3-4hrs now. Hardest part is putting the new belt on, but the rest is just unbolting and bolting back up

Like Clames said, there is usually no indication that it's gonna break

I have a 2004 Tundra with 245,000 and driving like brand new. I've put nothing but routine tires, batteries, and fluids to keep it going. I still have the original timing belt and water pump (if it doesn't break leave it alone). The O-T can argue all day about this brand of truck or that brand. But it'll be the Toyota still driving after Nuclear Holocaust.

You do understand with that engine if the timing belt breaks you buy another engine?

I’m to the point of needing a new timing belt in about two years. By then, it will be a 12 year old vehicle with 200k miles (changed timing belt/pulleys/water pump at 100k). Was looking to see how far I could push it.

ETA: 14 year old truck, not 12

I'm not a mechanic, but this goes against everything I've ever seen and makes 0 sense. Most manuals say to inspect for visual signs of wear, replace when needed.

The problem with the "conventional wisdom" line of thinking is that; 1) there's a lot of bullshite mixed into it and 2) what you are saying has absolutely zero to do with these Toyota eninges.

The OEM belts are actually made by Mitsubishi and they can stretch considerably without showing any obvious wear. The tensioner can only take up so much slack though and if you let these belts go for too long they are also as likely to jump their timing, which is just as bad as breaking with an interference engine. You can't do a simple visual inspection on just the belt, you have to check the tensioner which to get to means you have pulled almost all the parts necessary to change the belt out anyway.

So much this! I have a Tundra and a 4Runner both with the 4.7 and aside from timing belts/water pump at 90K intervals the only thing I've ever done to either is fluids and tires.

I was putting gas in my Tundra once and a guy on the other side of the pump started a convo about the truck. Said he had one that he handed down to his son with well over 400K with just timing belt, fluids, tires. He said it would still be going if he hadn't gotten t-boned.

ETA: I take that back, I did also replace the drivers door window motor on my truck last year at $50 and 1/2 hr work. What a POS!

Google / manual .. Oh wait Tennessee ?? Can't read , my bad

5.7 has a chain.

No service interval from the manufacturer.

Not the same vehicle, but I waited until 140k miles on a Honda Civic, which was twice the recommended. The old belt still looked damn near new off the shelf. Changed the water pump since it was exposed, so that made the work worthwhile, but the belt looked like it had much more life.
