Squeaky belt... eeeeee

[dimi_108]

Right. So one of the belts are squeaking on idle.
This morning when i started the car, the squeak was loud. After driving the car to work (25km highway run at 100km/h), as i parked the car, the squeaking was quiet, but still there.
It rained heavily last night. I don't know if that matters.
But the same thing happened when i degreased and used the gernie to clean my engine bay two weeks ago - the squeaking happened for an hour after this and then disappeared.

Has anyone experienced the same thing? Really annoying.
I read on the Delica forums that you can use a bar of soap or brake fluid to fix this. Hmmm

ps/ac tensoner wheel bearing.

i know so, mine does the same thing,

water is/has been getting into the bearing,
normally the factory engine tray would sheild it,

it does it till it drys out, then its semi quite,
then gets wet again and it wines again

Makes sense.
I've removed my splash guard under the car, too. Could be the reason why the belt is being effected by puddles so easily.

Is it an big job to replace the tensioner wheel bearing?

 

[Guest]

not really,

undo the bolt in the middle of the tensoner wheel,
then loosen off the tension,

then remove the center bolt completely, off comes the wheel.

Thanks man. I'll get it looked at on my next service.
Are there any fixes you can recommend for now? Put the splash guard back on?

You really should keep it on anyway

 

[dimi_108]

Of course. I just I removed it to monitor my rear main seal leak.

dont put brake fluid on anything unless you want eaten rubbers... that shit will eat through stuff. its a very easy job to chage the wheel, would prob take around 30mins and thats 15mins of mucking around with a jack and stands.

My car didn't come with the under tray. I have a squeaky bearing in there somewhere.

I'm hoping its just a tensioner wheel but I suspect it's something more sinister than that... seeing as the AC pump wheel doesn't seem to turn square / true.

Clearly I should just wait until the noise is so loud it's obvious. In the mean time I need to tension my belts again as they do a nice 5 second squal whenever I start from cold.

Squealing like that does just sound like a slack belt - they need to be pretty tight. Give the tensioner a couple of turns and see if the noise goes away. Bearing squeal and belt slip squeal are different, but can be impossible to tell unless you're experienced with both. Bearing squeal will continue pretty much the same no matter how tight you do the belt up, so do it up nice and tight and turn the engine over - no squeal = slack belt. No change = bearing

Just ensure you don't OVER tighten your belts - there shouldn't be much give in them, but there should be some - if you can't bow the belt at all by leaning on it, it's too tight. It should have a few mm of flex with reasonable pressure.

Finally, if you do the belt up REALLY tight and the squeal goes away, but adjusting so they seem about right makes the squeal come back, you've probably got a glazed belt - basically the rubber's getting old and there's been a bit of slip for a while which has caused a hard finish to form on the belt. If that's the case you'll have to change the belt to fix it (although it probably needs a change anyway if it's old enough to glaze).

i gotta get around to changing my a/c belt, its all chewed. thats why you should have the stone tray on, looks like something has come up and hit the belt..
