IS350 Tensioner pulley replacement

In this video I show what I did to replace the belt tensioner in an 2006 IS350 without having to evacuate the a/c system. It is possible!
parts i used for my car are
16604-0P011 Idler Pulley
16620-31021 Belt Tensioner
99367-K1550 Serpentine Belt
all my parts I ordered from
Oemvehicleparts.com
OEM parts up to 35% off
I verified that the parts actually come from a dealer. So it's legit.

Wow. Lot more involved than I thought.

I bet all you needed to do was replace the pulley and not the tensioner. I did it last weekend and it solved all the noise issues. I replaced the 2 idlers too. Definitely worth trying this first instead of taking the whole engine apart to replace the tensioner. Bad design Lexus!! Great video. Thanks

[@familygromscarsfun3896]

You know i really would have had the technician said the tension has a tendency to sieze and would snap the the belt if that happened, and leave you stranded. So i went ahead and just did it to not have any issues down the road.

@@familygromscarsfun3896 - scare tactics - but at the end of the day you have to be happy and that’s all that matters! Now you don’t have to worry about it in the future

[@familygromscarsfun3896]

@@condor5635 yup. Agreed. Thanks bud.

It’s actually safer to replace the whole thing! Replaced the pulley and noticed the bolt was stripped and wouldn’t hold the pulley correctly. That coulda been bad later down the road haha

[@ruthnoya8424]

Agree completely. I'm all for OEM parts (Bell Lexus has great sales a few times a year) but I've researched the topic and many people even use non-oem, not model specified pulleys to replace the tensioner pulley if they choose to not press in new bearings into the original. A pulley is one of the simplest components on an engine. The only time I'd spend the time, money and hassle is if the tensioner was not working properly (ie. keeping tension on the belt).

[@johnwedgeworth4908]

Wow, all that just to replace the tensioner is ridiculous!

[@malik.b3042]

I can’t find the back bolt, or the third bolt. Under the AC compressor

Hello friend, I am planning to replace a new belt, wish you were showing how to put the new belt back in detail..!! 👍

[@familygromscarsfun3896]

Just look at how it is before you take it off lol or takea pic. sometimes there is even a diagram that show the correct path for it.

[@cncmachining7568]

Hello friend, I am planning to replace a new belt. Wish you were shown how to re-install the new belt in detail..!!

[@familygromscarsfun3896]

Just follow how it was on. take a pic if needed. i just loosen the tensioner to take the belt off. then once the belt was off. and i was done. i routed the belt as it was then lossen the tensioner like i did taking the belt off, and slipped the new belt ojn. super easy! You got this!

Hey, I just did my serpentine belt and my idler pulley on my 2012 IS350. I noticed my belt tensioner seems wobbly, is that cue to replace it? It sounds completely quiet now but I wanted advice. Thanks.

[@nicoray15]

yeah its probably a good idea. if tensioner fails it will snap ur belt. ask me how I know :)

[@jeffgrantIS350]

I must have missed the reason for the replacement... was it just making noise and you decided to change it out as preventative maintenance? I'm considering replacing my Serpentine belt on my 007 Lexus IS350 with 160K because it has never been done before. Should I consider replacing other pully's as well?

[@xXBigWedoXx]

If you’re gonna replace the belt might as well do the pulleys as well. Unfortunately I had to replace the whole tensioner because the bolt holding the pulley was stripped. I have an extra OEM tensioner pulley for anyone looking to buy

[@familygromscarsfun3896]

I did it as good maintinance. The tensioner can sieze and snap the belt.

[@carloscortes1520]

My tensioner pulley seems to rattle but only sometimes. Which makes an slight rattle and chirping sound. Is that your similar experience?

[@xXBigWedoXx]

Yes, you can try replacing just the pulley without the whole tensioner assembly. But they only sell the assembly WITH the pulley already on, so you might be left with an extra pulley like me 😆 let me know if u need buy I’ll post to eBay

[@familygromscarsfun3896]

The reason they sell the whole assembly is the fact that the tensioner gets siezed sometimes which will snap the belt and lead to a whole world of headaches.

How did you move the sway bar out the way

[@familygromscarsfun3896]

I just unbolted the sway bar busshing mounts to move the sway bar out of the way bud.

[@hVSjRJ53]

How long did it take you to do this repair?

[@familygromscarsfun3896]

Not very long, i'd say maybe 2-3 hours to make sure it went as planned. saved me a lot of money rather than having a shop or the dealer do this work.

[@mcp08gt]

Would this be similar for the is250?

[@darkzeronemesis497]

Exactly the same
