Navara Screeching

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.

V or ww type pulleys and belt?...silverback

Try with and without A/C on if it squeals with A/C tighten the belt.

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

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.

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
