All: Well, I bit that bullet and had my 1998 Avalon's timing belt and water pump changed today. I also had some new drive belts put in. Still runs smoothly; although, I notice a bit more of a whining noise when the car is in idle. Whew, I am glad THAT is over. :-)
All: I forgot one thing. I asked the mechanic for the old belts and pump for examination. Now, where do I dump them? Do I take them to a public junk dumping ground or what?
Trash the old timing belt, and put the water pump in your recycle bin if they take metals.
Old fan belts are marginally useful if they aren't already way too far gone and visibly cracking and failing - If you don't carry a new belt, toss the old belt in on top of the spare tire.
If your fan belt breaks halfway between Death Valley Junction and Baker (IE the proverbial "middle of nowhere") and you are carrying a set of basic hand tools, you can install the old fan belt as an emergency measure. As long as it lasts the 50 or 100 miles you need to go as you drive back to civilization, having a spare belt with you (even a used one) can be worth it's weight in gold.
You can count on a passerby picking you up, but I hate leaving that kind of stuff to chance. Your luck, it'll be a day or more before someone comes that way again - and Death Valley can see 140F during the day and 40F that night...
I'd think the car will become quieter so maybe you want to identify where the whine is coming from. Now did they change out the idler and tensioner pulleys? And cam/crank oil seals?
