I wanted to ask this question in an new thread but cannot post UHGG

2002 4 runner 270k on the vehicle. I wanted to replace the motor the little woman said no

It was time for a timing belt last changed about 150 k or so

valve covers were leaking some of the hoses were original. I decided to jump into both jobs

I bought this kit for timing belt

NEW Genuine 14PCS TOYOTA 3.4 V6 5VZFE Water Pump Timing Belt Kit 4RUNNER TUNDRA | eBay

I would not say things went smooth as its been awhile since I have wrenched on my vehicles for awhile even though I am tooled up but I am rusty if you will.

My go to mechanic sold his shop cashed out and retired to AZ. You would think since I have known him since Jr High he would have consulted me and could have persuaded him to stay. Where am I supposed to take my cars now? What a dick.

work got in the way and the vehicle sat torn apart which always makes it harder for me. Had time off an emergency got in the way. So be it Life happens

had a ***** of a time getting the timing belt on

here is my conundrum

Part number 13505-62070 IDLER SUB-ASSY the one with the 10 mm allen key fit perfectly into tensioner and bolted right up torqued to spec

once I put the timing belt on it seem to not ride on center of roller as I expected. I double checked part number and it was the correct one ( or if I am wrong lmk)

I decided to roll with it

then the lower dustcover the one that goes over the crank would not got as the assembly was further out.

I looked at it thought all the parts are right I will space it out. I used 3/8 nuts checked the clearance ant put the rest back together

everything works fine however

Now it squeals like Ronnie James Dio at a Sabbath concert.

maybe not that loud but fn annoying unlike Dio whom I rather liked in Sabbath

Any idea if this part is correct or where to find the right one?

Or perhaps my squeal could be elsewhere?

I assume as that was the one part that was different as I said I am rusty

any suggestions would be helpful

Sounding like your timing belt is not aligning properly on the pulleys. Are you sure you have all the pulleys in their proper location. As I am not sure what you all had off.

OR...

Your 3 other belts are not tight enough. Can you pinpoint exactly what is making the noise.??

Sometimes you have to pull the belts off one by one to find that. Now if you have all 3 belts off and its still making noise. Then you know its timing belt related. :-)

Thanks I appreciate any input

I like the idea of removing the belts great tip!

Thanks will perform that

The belts seem to be aligned including timing belt

The idler sub assembly sticks out to far for dust cover to go on will still be an issue no matter what I find there.

[Glen Gallo]

Oh my bad

I had everything off

upper and lower dust cover, radiator and cover fan and housing all belts water pump all covers replaced camshaft and crank seals

[Dezert4Runner]

Like mentioned, it sounds like drive belts are probably making the squealing noise. I did my TB a couple weeks ago and my alt belt was loose enough to cause the squeal on startup for a couple seconds.

The #2 idler pulley needs to have a washer on the back side of the allen mounting bolt. That could cause the issue you’re having I think.

so all belts off besides timing belt

the squeal improved with driving before removing but did not go away

its still there so on the timing belt

anyone else ever experience having to shim the lower dust cover out to install due to the #1 idler assembly sticking too far out

Thanks for the help

Amazing resource this forum is

This is definitely an option, I think. I just can't get the angle right in order to get the socket to turn. I'm also doing this with the truck on the ground. But I can't imagine that's my problem. This is some food for thought though that I had not thought of, so thank you for that.

No.. I did 3 of these on 3 different 3rd gens using the air cabin kits.

Does this #1 idler assembly part number match that in diagrams from Toyota dealers?

I suspect whatever is wrong, its has to do with the lower dust cover is the problem area..

'Does this #1 idler assembly part number match that in diagrams from Toyota dealers?'

yes

ebay kit purchased here NEW Genuine 14PCS TOYOTA 3.4 V6 5VZFE Water Pump Timing Belt Kit 4RUNNER TUNDRA | eBay

all parts match my vehicle


'I suspect whatever is wrong, its has to do with the lower dust cover is the problem area'

The odd thing is it was fine when I took it apart.

I am going to have to put eyes on it.

not sure when.

Is the cover the bottom one over the crankshaft? If so, your gear might not be fully on or not put together properly. As they have to slide back over the key a 1/4 or so on the driveshaft. I suspect that maybe your issue.

If it's the top one. Are your camshaft pulleys on properly? Is the center puley correct?
