Welcome from Western NC!

 

Something not right. Who is doing the belt install?

 

I have a 2007 SR5 tundra. Dont remember the brand of the belt i used. First and 2nd replaces belt was out in by father in law cause I was away at work. 3rd was a mechanic.

 

Something loose? Any of the pulleys? Seen members on here like the Gatorback belt..I like Gates

 

Think the belt we used was dayco.

 

Duralast from autozone.

 

I just replaced the pulley cause it had a little wobble in it. Thinking i might hv to replace tensioner assembley also. It’s a 5.7. Liter

 

Called dealer to get a price. Said about $123.

 

5.7, correct? If so, here's a link:

What about idler pulley? 5.7 ffv

 

Idler pulley is fixed, but I guess it could be off. Here's a link to it, just in case:

Thanks for the part info.

 

When you say "fan belt" we're talking serpentine belt right? One of the only issues I've ever had with a Tundra was the serpentine belt on my 07. It had signs of cracking at only 35k. It was replaced by the dealer 'cause there was also a water pump leak that was still under warranty. Well, the dealer didn't line it up right, all the grooves weren't in the slots correctly and the belt shredded within a couple k miles.

 

I had my water pump replaced about 6 years ago. Had a crack in it. Didn’t notice any difference until I needed oil change and they took skid plate off. It had collected on top of it.

 

Is this your price shipped to 77080?

 

It's part only. Once you add it to your cart, you can input your zip for a shipping quote. Shouldn't be too much on just the tensioner.

 

Thank you!

 

I had to replace my Serpentine Belt on my 2020 Tundra with 13 000km. Only a 1000km after, it's starting to make the same noise....It's squealing hard under idle. I'm not sure what to do anymore. I'm very disappointed in Toyota products. I made the change not too long ago to Toyota and if it keeps happenning, I want to get rid of it.

 

Take it back to dealer, under warranty right?

 

Yes, had the same problem with my recently. The whole tensioner should do the trick as others said. Check the fan bracket bearing too when you have the belt off.

 

I will be the 2nd time for the same problem.
