Serpentine Belt Replacement 4 cyl specific

im starting to think it may have been the fan clutch making the noise im going to check it out tomorrow, I was having a real funny noise just like the fan blades hitting the plastic shroud was messing with it doing some tests, this type of noise is the first time ive heard it, ill let it cold soak overnite pop the hood tomorrow and see where its coming from after some driving went away today getting to operating temp within no more than 10-15 minutes. im going to try these tests

Not a bad idea, I'd think if the serpentine belt was really that far out of tension you would be prone to pitching the belt. Keep me posted..but still I'd say change the thing anyways at that mileage

 

im going do a few tests with the fan clutch not too hard to do, if it pans out ill get a new OEM belt 90916-02708 they've come down in price quite a lot and Made in Japan https://parts.conicellitoyotaofconshohocken.com/oem-parts/toyota-serpentine-belt-9091602708

 

Excellent write up and photos. Maybe you could help me out, do you know the OEM part number of the 2.7L belt?

 

All.....you really don't need a tool (gage) to see if the belt is worn.

Look at the pulleys. If the crest (point) of the grooves is shiny, then the belt is worn. This comes from the belt sitting deeper in the grooves with the pulley crests being driven by the valley of the belt.

The belt is designed to drive on the sides of the V.

Other clues to belt replacement are shiny (glazing) belt (drive side or back side), cracks (anywhere) and slipping (of course). Generally, these indicators are evident before slipping begins.

One more tip. While the belt is off, take a couple minutes to inspect and clean the pulley grooves.

 

Disregard my post above. I see the new part number is 90916-02708.

 

I contacted GATES belts they sent me a free belt checking gauge https://www.gates.com/us/en/customer-support/contact-us.html my belt OEM has a 125k miles on it and using the gauge its still in serviceable condition

Mine looked okay at 113K but I managed to come into a free OEM replacement, being that the winter is coming I just said fuck it and changed it along with the spark plugs it definitely needed.

 

OEM belts are better than aftermarkets, even tho there are BANDO aftermarket belts they aren't as good quality as an OEM BANDO as far as longevity and noise issues, plus ive noticed the OEMs are coming down in price to around $45 lately

 

No sir.

Your belt is listed at 90.5 inches here https://www.vbeltguys.com/products/4060905-goodyear-oem-equivalent-serpentine-poly-v-belt

The Google machine refers to this as a replacement for your belt, which is listed as 90 inches https://mechanidrive.com/900k7-7pk2285-2010-toyota-tacoma-equivalent-serpentine-belt-ab881318/

I'm not saying that exact brand is good or not per se just that it's where I found the measurement.

"Could" you try to get away with using the one you have? I suppose. Would I suggest it? No. If the slack pitches the belt, best case you're stuck and worst case it damages something else.

The belt is cheap enough and a fast change, I have a '10 with the same engine.

 

This is an old thread, but thanks for posting this. It looks like I need to do this on my 2021 (already).

 

2nd this. I recently replaced my tensioner and belt, did it all from above so you can skip the “drop the skidplate” step. A much easier job than a European car that sometimes requires special tools. I’d say it took about 30min for belt & tensioner but that’s with me checking the idler pillows and inspecting the others for damage/freeplay/wear.
