More traffic here than in 4x4 & trucks......

Bought this used Lexus GX 460 a few weeks ago.....95K miles....sooo

Change the main drive belt right ?? OK ..and plugs...replaced with OEM Toyota..$50........

Could have got a Bando for for $24.....my mechanic buddy install.....

Squeals like a pig being shot from a Helio @ 200' in the air......

When hot.....sounds normal.......sprayed belt dressing on......waiting for any effect......

Also ordered an idler tension pulley pulley to install if needed.......

Am I going in the right direction.......? TIA

yea.....this '11 Lexus is one nice ride

Put on a goodyear gator back belt on it, problem solved!

OK............really thought the Toyota OEM would be the boss........

Looking at a GX460 for the wife. How is it off-road? They're basically a Toyota Land Cruiser Prado with a different front grille and nicer interior.
We have a Sequoia now (3rd one) but since the Daughter's off to college and we're not doing the travel ball, school sports thing all the time, we don't need such a big vehicle. Wife wants to downsize, were stuck on Toyota's so it's either a 4runner or GX460. I'd like a 4runner trd pro, but I'll rarely drive it, so her choice.

Grocery getters aside and assuming proper installation are you sure they gave you the right belt?

Grocery getter? Pull that F250 out of the mud when it gets stuck!

Make sure the belt is routed properly. There's usually a diagram somewhere under the hood- - - - -if one of the heavy load pulleys like the crankshaft pulley, alternator, or the A/C compressor doesn't have enough of the belt wrapped around it, it will squeal. Since it's only happening after startup, pay particular attention to the alternator. Recharging the battery after startup puts a lot of load onto a very small pulley.

Did it start after the new belt install? If it did then as suggested check belt routing. If noisy before then Stethoscope to listen to each of the pulleys on the system to find the noise. Or take the belt off and spin each one to check noise/roughness as spun.Also recommendation of replacing tensioner at 100k due to stress.

C'mon man, they are F350's.....

I googled "Toyota w/Hydra bed" and got nothing....
You ranchers gotta get with the program. A tundra with 2 round bales on the ass end and a Trump 2020 sticker on the back window would be MAGA.

Dude, about a month ago we had to borrow a loaner from the local Ford dealer.

Ext cab F450 with a V10.

It rode WAY smoother up front and I loved it off road. Floated around and took off easy when you gave it a little gas.

But it sucked major ass pulling the little hills around here loaded going down the highway. It wasn't totally gutless but I could instantly tell a big difference.


The 6.7 is a beast though, turbo diesels kick ass.

6.7 is a winner for sure. I have duramax in a few but my buddies 6.7 makes me want a Ford for the first time in a long time. Last ones I had were 7.3's in a couple F350 utility trucks close 15 years ago. Still have a 7.3 navstar in an international 4400. Has 490,000 on it. Smokes like hell on start up but runs like a scalded dog.

Big V8 gassers, I have an 8.1l in a GMC 6500 with a 6spd zf trans. Bitch pulls like a locomotive. Gets gallons to the mile though.

I have a 4runner, nice vehicle but the seats sux. Not much for padding in them, other than that I really like it.GX460 should be nicer seats

The 4runner is a helluva lot better looking IMHO.

Clean the pullys with a wire brush?
A little packed grit, salt, dirt in the pulley grooves will keep belt from seating properly...
A little lube on the tensioner and work it a few times? Salt corrosion/crust can limit its travel. Both can cause a new belt to glaze up quickly...

Did you wiggle your pullys when the belt was off to see if you have a bad bearing somewhere?

Be a pimp and get a Ford Tremor!


I'd take one....

Sheeeit....I'm a base model truck guy. No carpet and vinyl seats for me. Only thing I want is power windows, mirrors
And cruise. And a utility bed that doesn't leak water through the doors!

Same here.


Couple days ago I priced out('built') a pickup on-line.

Reg cab SRW F350 XLT with the new 7.3 gas and it was $48k. A bed is about $12k.

Ain't happening this year!

$60,000 for a gasser is complete B.S.
I'll take a 5-6 year old low mileage truck every day. 10-15% depreciation in the first year is stupid. With A base model truck, I've rarely used the warranty ever, so that holds low value to me. I treat trucks like [bleep], admittedly, so I could care less about the year/physical condition. I put 45,000 a year on mine and live in it 10-12 hours a day.

Make sure the belt has the same number groves as the pulleys.

If they are correct might look at the idler and other pulleys.

Belt dressing sucks. I’ve never seen it work, and usually the belt noise will come back louder. Shouldn’t have had to use it on a new belt anyway. Something else going on.

In my 4.7 my belt was squealing because the power steering hose had a leak. New OEM belt and hose fixed it. Hose was 400.00 because it had some goofy fitting. There was a generic, but my mechanic insisted on the OEM.

thanx for the replies.......

old belt was as quiet as a church mouse.......

Ordered an idler tension pulley......will have my mechanic bud double check routing

This is wife's DD.......not going off road to speak of........yet

pic from CarMax pic file when I bought the car.....interior is nice & comfy..quiet

yep.......its a Prado in the States

https://en.wikipedia.org/wiki/Toyota_Land_Cruiser_Prado

My old Dodge truck did the same thing. Put on new belt and it started squealing. The new belt was ever so slightly wider and was touching the side of the pulleys. Hardly noticeable by looking at it, but it squeaked.

Can't remember which brand was which, but it was either a Kelley or Gatorback and one squeaked and one didn't


Clyde

ordered this OEM belt from Bell Lexus in PHX AZ

P/N should be correct

Good guys & fast shipping if you need Lexus parts

These are your first steps. How is the tension on your tensioner? Belt dressing is not meant for serpentine belts. Make sure your buddy degreases all the pulleys before he installs a new belt so you don't get contamination on that one too.

Love these belts. They wear like steel and run so quiet its crazy.

+1

If not the idler pulley, it could be a bearing in the alternator. Do the pulley first. If it still screams, start it without the belt on for a few seconds, if it stops you'll know to look at the alternator, steering pump, etc.

U P D A T E ...........................

belt never stopped squealing....again on initial cold start in heated garage

well........ordered a new belt.........Continental from Amazon......$38

Also bought a new idler tensioner.......$60

My mechanic bud installed both yesterday...said he removed fan for extra work space

Yes.....he put it back on.......

So...seems that was the issue.....quiet as a church mouse now......wifey very happy now.......

Next project.. Iron Man 2" suspension lift kit......can't have the only Lexus in Podunk & not look badd azz
