new timing belt shredded with less than 200 miles

I just had a new timing belt put on my 2000 Prerunner and it shredded. It had less than 200 miles when it happened. Was driving about 25 MPH and the truck just shut off. The guy in the tow truck said he worked on them for over 20 and asked for the keys. Soon as he stuck the key in and turned it he said it either jumped time or the belt broke. What does non-interference mean? I've read that if the belt breaks a new belt can be installed and you can go your merry way. Then someone else told me if it the belt breaks the engine is toast!!!! It is the 3.4 V6

 

3.4 is a "NON" interference engine. That means when the belt breaks the pistons will not slap the valves and cause damage. Who put it in? If Toyota did it, you have a 1 year warranty on their work.

 

I know a guy who has been working on them for over 40 years. He said he will take care of it

 

Non-interference means you are lucky. You can just get a new timing belt, line all the marks up, and be on your way. If it was in interference engine you might be getting a new engine or a new truck. The pistons would have hit the valves and bent them and possibly the rods.

 

It might be good to figure out why the belt shredded in 200 miles unless you want the timing belt replacement schedule to be every 150 miles.

 

I imagine either the bearing wasn't replaced and seized, something was misaligned or the tensioner went out.

 

As others have said, your motor is more than likely fine. The only complicated part when reinstalling a new belt is getting the timing correct. If replacing a worn (but not broken one) it's easy as long as you don't move the crank shaft or cams when you're working on it. It's a little more complicated when the belt broke, but it's just a matter of rotating the cams and crank to the proper position, then installing the belt.

But I would for sure go back to whoever replaced your timing belt and read them the riot act and demand a refund so you can have someone who knows what they're doing work on it.
