Why does coolant level drop on Avalon XL?

Why does coolant level drop on Avalon XL?

I noticed on my 2000 Avalon XL that the coolant level in the overflow reservoir drops a couple inches every year. I understand that temperature affects the level reading; however, I usually check first thing in the morning and compare the readings in similar ambient conditions (i.e., similar weather conditions, etc.).

Can a 2000 Avalon overheat on a long hill?

My 2000 Avalon with 140 thousand miles will overheat on a hot day, at least the gauge shows so. On a long hill the needle will rise almost to the red. A couple times it was in the bottom of the red. I had it into the dealer last summer he drained and replaced the anti-freeze and could find nothing wrong.

Why do you put water in the coolant reservoir?

If you use straight coolant it would expand too much and overflow even the reservoir under normal engine temperatures. The water actually helps the coolant work better in your car. Second, coolant can vaporize in the presence of oxygen, so if it is in the reservoir, and its hot, it will evaporate.

Which is better a mixture of water or coolant?

Here is some background information. Coolant is better than water because it stays liquid below water’s freezing point and above it’s boiling point. But it does have a nasty tendency to expand more than water when it gets hot. That is why you need a mixture of water and coolant.

How many miles does a 2002 Toyota Avalon have?

However, my dad loved it and so I decided to give it a shot. I purchased the vehicle when it had 44,000 miles. It’s been more than 3 years and it now has 85,000 miles. The 2002 Toyota Avalon STILL runs perfectly. It’s comfortable, spacious, smooth, and everything you need in a reliable car.

What was the Toyota Avalon not at fault for?

First one was not her fault. (2001 Model) Rainy weather, car cut across in front of her. She hit the brakes and broadsided them at 45 mph. The ABS kept it straight. After the wreck, looking at the car it was textbook perfect crumple zones. The car dispersed the energy of the crash evenly throughout the structure. They all had on seatbelts.
