My 2002 Prius is making a loud noise in the gas engine side (vibration or possibly water pump?). I've got 189,000 miles, so I'd rather not take it in to the dealer. Anyone know where to find a motor diagram for free?

Re: loud noise in gas engine
I am a fellow Prius owner, mine only has 8,000 miles though ;-) If I was you I'd just bite the bullet and take it to the dealer. Worst case is you're out the $100 or whatever they'd charge to diagnose the problem. You can always fix it yourself but if they do a proper diagnosis it could save you money in the long run. Does it sound like the noise is internal? You may also want to search or post at PriusChat.com, a Prius forum.p.s. Congrats on getting 189K miles on it already, these cars last a long time, I'm very happy with mine.

Not sure of starting problem, but you may have bad engine mounts causing the vibration/roaring noise. hav ethe engine mounts check. These vehicles have a history of bad mounts especially after 100K miles or more.
I have a 2002 saturn vue. Same thing..sounded like a jet engine ...loud humming as I accelerated . It got increasingly worse. It turned out to be the front wheel bearings. Replace them, now the noise is half as loud...have to do the rears also! 93,000 miles on it. Also, don't forget to replace the timing belt. It it goes too long and breaks, it will trash the engine...
;You most likely have a wheel bearling or hub assembly that is bad. You should be able to narrow the hum down to one side or the other. Other possibilities are a noisy engine accessory, such as a bad bearing on a alternator, or power steering pump, but you should be able to make that noise show up, just by rev ving up the engine, so if it only shows up when the car is moving, check out your wheel bearings.
My rio kia bought on from uyi technical dealer in benin city, edo state of nigeria only 4 months ago is vibrating with noise while driving. The noise is noticed by other road users even in motion, making a very loud noise or sound that is highly embarrassing. The dealer mechanics have checked more than twice yet no result, instead the hub bearing is observed; tyres are turn over yet the noise persists.
What do think is resolution to the problem? pls help me. Vinson- firstname.lastname@example.org
