Hi all, our daughter has a 2002 Navara, the problem is when it is running there is a terrible screeching coming from the front, we think it may have something to do with the fan belt as when it is running and we spray it the screeching stops for a bit and then starts up again. All pulleys and bearings have been checked and are OK, the belt has been changed but the same thing occurs. Has anybody had this problem or know how we can fix it.

Cheers

Sounds very much like the same problem we had with a near new Hilux . ( Refer post Jan or Feb screeching Hilux)Turned out to be the water pump dust seal. Hard to find as intermittent. Dealer diagnosed with stethoscope - you might try with a big screwdriver to the ear, I think best the pointy end not to the ear, and be very careful of moving pulleys, fans and belts.

Regards, John.

BTW Brian Hilton Toyota Gosford very helpful - not connected with them but dealers get some deservedly bad press here at times, so a good rap occasionally is warranted.

Thanks for that John, it's definitely somewhere to start, It does sound like the water pump but that has been checked out but will look at the dust seal.

Cheers

Hi silverback, sorry but I'm very ignorant on these matters and not quite sure what you mean, I know what a v belt is but not a ww, the only thing I know is that it is the drive belt, when it gets sprayed it stops for a while and then starts up again.

Cheers

the ww belt is a wider but thinner belt with a multi ribbed vvvv looking under side, it flexes more easily,generating less belt heat and stress and much less likely to squeal, a much more modern belt and I would have thought it would be what you have...silverback

yeah that is what it is and I thought that was what you were asking but wasn't sure, it is a much wider belt than your normal v belt.

Hi Doug, we have tried tightening the belt. it is only an annoyance factor, we can hear her coming up the road and it makes people look at you whilst driving along.

Thanks for the reply.

Cheers

Hi D,
I have a similar problem with my Rodeo TD when I go camping up NSW. After driving around the dusty tracks and stopping for a while, the Rodeo starts screeching when I start up again, I give all the belts & pulleys a squirt of water and then start up again, screeching stops, happens again if I travel over dusty tracks again. Doesn't do it at all when not driving in the dust.
Due for a service soon so will get everything including dust seals checked out then.

Regards,
John

Ha ha ha ha, Hi John D, it does sound funny not being able to take a 4wd on dusty roads. Having said that our daughter hasn't taken hers off the bitumen yet and she has had it for about 18 months.

Cheers

An old timers trick,
get a cake of soap and with the engine stopped rub the soap on the underside of the belt wherever you can do so, turn the engine over a little then repeat the same then start the engine up and run the squeal should cease.
I used to have a handle on life, but it broke.

Cheers Dodg.

It is amazing how well some of those "old timers" tricks work,

Thanks for the reply.

Had exactly the same problem over 2 years back.

Annoyance factor/Service bay $$ maker, on the flat belt.
I am sure its built in

I did myself
Everything off, all bearings good, took off belt tensioner ( mongrel thing ) sprayed Inox on it, put back on ... still squeeling/squeeking..

Alternator off, Inox into the rear of pully
New belt, lots of belt lube,,,,

Only thing left was waterpump,, ( big $$$ I thought )
All of a sudden 3 days later, all stops..?????//
Phew !
Never done anything like it again, still same gear on Navara ?


You tell me ????

Cheers
Bucky
