On a 2000 Avalon, should I replace the water pump when the timing belt is replaced?
On a 2000 Avalon, should I replace the water pump when the timing belt is replaced? And what about the Tensioner belts? Should they be replaced as well?

The Toyota Avalon was redesigned for the 2000 model year, getting many high-end touches like a wood-trimmed interior with leather accents. The new Avalon came with an upgraded engine, roomier interior, and many more high end options to choose from, putting Toyota’s full-sized sedan on par with more expensive luxury brands like the Lexus.
The 2000 Toyota Avalon comes in two trim levels, the XL and the more luxurious XLS. Both trims come standard with a 3.0-liter, 210 horsepower V6 engine. The XL is nicely equipped, including cruise control, antilock breaks, and a number of other comfort features. The XLS includes a few more niceties, like an upgraded sound system, alloy wheels, and a leather-wrapped steering wheel. Fuel efficiency is 21/29 mpg.
Toyota fans speak highly of the 2000 Avalon. They are especially excited about the high-end options, like seat memory and automatic climate control. They also appreciate the car’s reliability, excellent handling, and very comfortable ride. Most of the complaints are about the appearance of the car, which many find to be boring and even outright unattractive. Many also find the 2000 Avalon boring to drive, although it is not meant for drivers who want a lot of interaction with their cars.

2000 avalon electronics/ AC and windows not working after alternator replacement. The car starts with new alternator in it but I cannot roll down the windows, turn on the A/C, or lock the car using the key... I can start it, the headlights work, the power locks let me unlock the car. When I put a voltmeter on the battery with the car off it shows 11.75 volts (what it was prior to changing the alternator) and with the car running it shows less at 11.54 volts. I have looked at the interior fuses, tried disconnecting the battery again. Nothing seems to work. Please help.
Water pump went out,started streaming, noticed it was reading hot on gauge,pulled off road and cut it off. Let it cool down and input water in it. Now it won't start,cranks good but sounds like it's not firing. Is there a safety to prevent it from starting or something?
