Serpentine Belt Replacement and Tensioner Pulley - Toyota Tundra
Автокөліктер мен көлік құралдары
Replacing a serpentine belt and tensioner pulley on an 04 Tundra. Should work on any 4.7 Toyota motor and is the same general concept for most motors.
All that is needed is a 14mm socket and a socket wrench. I personally used a breaker bar for better leverage. But either way, no special tools needed.

Also, what wasn't shown was to use a 14mm wrench or socket and put it on the bolt on the center of the pulley. Apply pressure counterclockwise and the pulley will move giving slack on the belt so you can slip it off of one of the pulleys. Then reverse your ratchet and turn the bolt clockwise and this will remove the bolt and the large washer on the front. The pulley slips off and the new one slips on. Reinstall the bolt and washer, remembering that it threads in counterclockwise. Tighten it up good. Then apply pressure to the wrench or ratchet to get slack on the belt and reinstall it according to the belt diagram.
Fun game...take a drink every time he says "check this part number" and you'll be shit faced by the end of the video
All the dislikes, because you only reviewed the parts, did not show how to replace the belt itself
The OEM Toyota pulley is 4". The cheaper replacement pulleys are 3 1/2". They will work but reduce tension on the belt slightly and the smaller pulley will rotate more, meaning less life out of the bearings.

i barely got this before i ordered mine online. Oreillys and Autozone didn't even know until i asked them for the sizes they had available.
Factory pulley is 102mm. Aftermarket tensioner assembly mounts pulley center offset(closer to The belt) from the original with 90mm pulley. The smaller pulley has less mass and mounting it offset from the original means the outer edge the belt rides on is in the same position as the larger 102mm pulley. Same tension on belt. People saying the smaller pulley gives less tension are correct if you were to mount it on the tensioner arm for the 102mm pulley. They sold you the “3.5 inch” pulley(90mm) because the original tensioner is considered obsolete. Pretty sure aftermarket tensioners come with the 90mm pulley now. You can buy the 102mm pulley. I just got a Gates 102mm from oreilly but I had to specify I had an original tensioner or they would’ve handed me a 90mm pulley.
samething almost happened to me regarding the pulley. Autozone and Oreilly wanted to give me the 3.5in (90mm) but factory spec was the 4 inch (102mm). I asked for the 4inch pulley but they either had to special order or claimed they didn't have it. Also the pulleys they had were flat across where the washer and bolt are suppose to attached which would of been impossible to reuse the OEM bolt and washer. The OEM has a... indentation in the pulley design as you can see in this video at the center where the washer and bolt go. Basically for my 2003 4.7L Tundra i had to go with a Gates because of all those factors of the pulley size and the center indentation of the pulley itself so you can use the factory Bolt and Washer. I spent around $43 on Amazon one day shipping.
If it's a left hand screw you tighten it counter clockwise and vice versa if I'm not mistaken.

You're right. The description in the video is incorrect.
did it have a spacer or anything on the back of the pulley? when i took my pulley off, the whole thing disintegrated
My new pulley is tighting up while driving, had to pull over three times to loosen the pulley nut...why is this happening?
This didn’t show me anything other than check part numbers.
I’m watching this video as I’m driving to autozone to pick up the 4” pulley Bc they sold me the 3.5” LOL
A right-handthreaded stud will tightenas you turn it clockwise into a turnbuckle (Righty-Tighty!), just like a light bulb.
Exact same thing happened to me.... they gave me the wrong part. Ended up having to special order it
Wanted to know why it takes 2.8 hours to replace the belt tensioner and he didnt show that
I'm 61 yrs old; Need to figure out how to change out the belt tensioner on my first gen TUNDRA. This video stole 5 minutes of my life......Can I sue???????
Gates 36119 is the correct pulley for this
