I have a grinding sound coming from the belt tensioner pulley. To my knowledge you can't replace just the pulley but instead the entire tensioner assembly. Is this correct? And if so how hard is it to do? Trying to get it done myself and any advice is greatly appreciated. Thanks

Thanks for the info Mike. I was able to get the tensioner pulley off and I replaced the bearings fairly easily problem is the noise is still there. I guess that wasn't the problem to begin with. Since I accessed the pulley from underneath I was able to get a better feel for where the source of the grinding sound was coming from and it sounds like it is coming from the area where the water pump is located. Any ideas?

There are 2 Idler Pulleys as well. One more to the front of the engine. The other is closer to the water pump. Maybe one of them is the culprit.

A tech on the 3rd Gen Avalon forum(2GR-FE engine) said that when the water pump goes it sounds like a box of rocks. Also, in my experience, when water pumps start to go, in the early stage of their death, they sometimes make a short-lived, loud squealing sound when you start the engine up cold in the A.M.
If it were my vehicle, I'd go after all of the bearings first - tensioner/2 idler pulleys. You've done one of them and according to the article I posted, the most difficult.

Personally, I'd have to see some leakage(coolant) and/or what I just described before I went after a 2GR-FE water pump.

See post #5 in this thread - pro tech talking:

Just my 2 cents.

What I provided to is a compilation of 2GR-FE water pump threads I've found at TN/Lexus/youtube. There may be others. Seems like the 2nd Gen Highlander and 3rd Gen Avalon forums have had the most fish in the pond.

One of the threads I pointed to is a 2008 Highlander water pump job.

You can go to:

http://techinfo.toyota.com

and buy a 2 day subscription to factory service manual info. Last time I checked it was $15 for that period of time. Do this if you are not comfortable with the doc I've presented or what others might pass on.

Awhile back I pulled the alternator off my Avalon. It was dead - had it rebuilt locally. On the Avalon forum there were a number of threads that addressed this and just about all had a different procedure provided by the threads OP. I got dizzy trying to draw up a plan and said f--k it. Printed them all out and went after it. There may be slight differences from year to year as far as what has to come off and how you get it out. I'm one of these types that will yank something off even if not specified in the book if it gives me a cleaner shot at something else further down the trail.

Take pics and a lot of notes as you're moving along. Put nuts/bolts/etc in baggies with a slip of paper in each identifying where they go. Arrange parts in chronological order as they are being removed. Helps prevent reinstallation mysteries.

Mike the second link on the thread you listed for the water pump replacement looks exactly like what I'm seeing under my hood. Might take me a bit to get to it but I think I'm going to give it a shot. Thanks for your help I believe this should help me get the job done and I'll let you know how it goes, or I'll be back with more questions. Thanks again.
