Dayco5080950 Serpentine Belt

This fit my 2011 Toyota Tundra perfectly. Looks like a good quality, only time will tell.

I received a Dayco Gold Label-Diesel Grade Design belt. The generic sizing is 8PK2415. The belt looks well made and installed without issue, after remembering to slide the skid plate to the side to remove it on a Tundra. The belt threaded on without issue. There is a diagram of the belt routing with the belt packaging though it's easier to pay attention to the original belt routing as you take it off.Some people elsewhere mentioned some belt squeal. I haven't heard a single chirp, even on startup, with no belt dressing used. The belt has been quiet. Would buy again.

This belt is doing fine on my 2011 Sequoia after replacement. Be warned, these belts are TIGHT. I highly recommend the HF serp belt tool kit, you will need to use the short extension to get the tensioner pulled all the way back so you can get the belt slipped back on. Be patient, have a helper. Check youtube for more info.

Installed as part of the 100K maintenance on my 2013 Tundra. Thought it might be idler and tensioner so bought them also and no change. Put the old belt back on and no issues. So this will sit on the shelf...

The idler pulley I took off was imprinted as Dayco. Ironically, the belt was not. My belt was a Gates.

Outside of the Tundra being a difficult vehicle to change a belt on the belt itself seems to be well made. My only concern was the grooves don't seem as deep as on the OE belt but so far it does not slip or make any noice.

This is the OEM belt for a Toyota Tundra - for much less than it costs at a dealership. Belt installation went smoothly, and all squeaks and squeals disappeared.

2 year update, belt started squealing really bad. It will stop with a spray on belt dressing but only for a short drive. I only put about 10k miles on the belt in 2 years. I don't feel like this is very good and replaced it with a Gatorback poly v belt.  Goodyear 4080945 Gatorback Poly-V Belts 1 year, 5k miles update, belt squeals intermittently. Replaced pulley thinking it was that but no change. I don't drive the truck much so just using belt dressing for now.Original review: I ordered this belt to replace the factory one on my 2007 Toyota Tundra 5.7L. The belt looks like a quality piece and is made in the USA. To install on your 5.7L tundra first remove the skidplate, take a 14mm socket and a swivel and attach it to the tensioner pulley from underneath, pull counterclockwise to relieve tension on the belt and remove with your other hand. Reverse to install new belt. Very simple to do from underneath the truck. The packaging for the belt has a diagram for the belt incase you need it.
