my truck is making a weird squeaking noise and i can't figure out what it is, its constant and i can't hear it to well when i rev the engine but when it idles you can here it a little and when yoou kill the engine you here it alot. All my belts are tight and i am right on all my fluid levels, and thats as far as i got...I think its around the fan or one of the belts on the left it almost sounds like a seized bering....idk!!!
heres a quik video. [GVIDEO]http://video.google.com/videoplay?docid=-3855120732783991054&q=4runner+squeaking&ei=TyRoSKj mNoPCqgOltL3FAw[/GVIDEO]
Ps, i also know there's ticking but i can't find anything wrong with the engine and i think its just the injectors...

 

May be a bad pulley, but I cant hear anything over that exhaust.

 

oh geez, before I opened this I though it was another "I here a squeak at full turn" thread, lol



the vid will not play 4 me for some reason, but how old is the H20 pump?

another common and cheap-fix culprit are the belt idler pulleys. the way you describe it only squeaking at low RPM and when you shut it off leads me to believe it's a bearing in the belt system... could be an idler pulley, maybe even say a PS pump... without the video playing for me, I can't really narrow it down

 

thanks for you help, i think its probaly a pully, but i'm still not sure, here i'll put a direct link to google video if that helps...
Toyota squeak

 

click on the words "Google Video" at the top of the viewer, video wouldn't play for me either

 

it works for me :/

 

maybe there's a mouse stuck in there somewhere? hehe just kidding.

I hear a sqeak at around 15-16 seconds as the engine is turned off.
I noticed that the fan appears to rotate quite a bit after the engine has stopped.
Maybe it's the fan clutch going out.

 

^^^^don't even get me started on mice...when i took my intake silencer off i found 5 dead chipmunks in my airbox and a huge nest....it sucked... there was chimunk droppings everywhere and my engine bay stunk.

 

but I bet that fur helped the filter.
anyways, good luck.

 

thanks, i might just replace the pully and see what happens...
