Where can I find a quarterly or yearly breakdown of
mileage Driven in the US? It would be nice to see
a detailed breakdown of who's doing this driving.

Data contains annual vehicle miles traveled by state and functional
classification.
This page allows you to selectively download data in comma-delimited
format from the table you chose.
To download data from specific time period, make selections from the
Filter Year and Filter Period drop-down lists.
To download data for specific geographical location (if available),
make your selection from the Filter Geography drop-down list.

Is there an article, study, report, anything from an
Accredited source saying that when your car runs hot
you can change your radiator and it will improve your
gas mileage?
=====================================================
Information regarding your second query is scarce; however I located
the following blurbs from online articles.
According to the AAA, a defective radiator thermostat can waste gas by
extending the engine?s warm-up time or decreasing the engine?s overall
performance.
http://www.aaasouth.com/acs_news/gasoline21303.asp
AAA Newsroom
http://www.aaanewsroom.net/Files/gaswatch02.pdf
?Defective radiator thermostats or a stuck brake caliper are common
maintenance issues that can contribute to wasted fuel.?
http://www.kuba1600.com/gas.html
From a posting at Google Groups regarding Radiators and Mileage:
?The car was getting about 14.5 mpg consistently (regardless of what
type of gas was in it, how I drove, etc.).Then I replaced the radiator
with a brand new two-row model, and my mileage has suddenly jumped up
to 19.5-20 mpg - consistently.?

Question 1 looks great, I haven't had a chance to fully review your
answer, but so far it looks perfect....thank you.
Questions 2 however, I don't feel was answered. These two articles
http://www.aaasouth.com/acs_news/gasoline21303.asp &
http://www.kuba1600.com/gas.html
are referring to thermostats and not the actual radiator. This link is
broken http://www.aaanewsroom.net/Files/gaswatch02.pdf and the google
group posting, has the exact the content I'm after, however I don't
really consider it an "accredited source." Do you think you'll be
able to come up with anything else? I would be willing to pay. Thank

Dear Redtippey,
Thank you for your clarification.
I'm glad that you're pleased with the first part of your answer.
Regarding Questions 2:
The broken link is also referring to thermostats and not the actual radiator.

I will do further research and hopefully I will come up with more
relevant information that is similar to what I found at Google Groups.
I agree that it wasn't from an accredited source but as I mentioned
earlier, this type of information is scarce.
Sincerely,

Dear Redtippey,
I have been searching for over four hours for additional information
about improving gas mileage with a radiator change. Unfortunately the
Goggle Group posting that I provided previously is all I was able to
find.
In any case, I sent off a few emails asking if a radiator replacement
would improve gas mileage and I will let you know when I receive a
reply.
Thank you for your patience.

To reconfirm this, I asked a Lexus Repair expert at "All Experts"
and he replied that you will not get any better fuel mileage by
changing your radiator; however if there is a problem with it you
should change it so not to damage your engine.
I hope this helps clarify the second part of your question.

Perhaps if you repost the question another researcher ?may? find an
answer for you. I am not very optimistic due to the fact that I
performed extensive searches and received negative replies from my
contacts when I inquired if changing your radiator can improve gas
mileage.

Yes I did.
I did not provide that link as I assumed that you weren't interested
in information about cleaning a radiator.
I had also found a link that said that cleaning the radiator doesn't
improve gas mileage.
I don't have that link right now but I will search for it and post it shortly.

Here is the article I was referring to.
?At my shop the term "flushing" the cooling system has been replaced
with "draining and refilling" the cooling system.?
(..)
?So, in a nut shell...draining and refilling your radiator with new
antifreeze every two to three years WILL help maintain and extend the
life of your vehicle, but will probably NOT have an impact on the way
it drives, overall fuel economy, cure a major over-heating problem, or
improve handling in wet weather.?

?Magna-Flexx installed on your cooling system will solve the
corrosion and scale build-up in your engine, radiator, heater coil,

From the car connection:
?Although today's newer cars have fewer routine maintenance needs,
cooling systems still require attention. Keeping the cooling system
properly maintained will not only assure that your engine is protected
from the summer heat, but it will also assure that you're getting the
best fuel economy and power on that long road trip by keeping your
engine at the right temperature.?

OVERHEATING: CAUSES & CURES
By Larry Carley
?Most engines today are designed to operate within a "normal"
temperature range of about 195 to 220 degrees F. A relatively constant
operating temperature is absolutely essential for proper emissions
control, good fuel economy and performance.?
(..)
?Radiator -- The most common problems radiators fall prey to are
clogging (both internal and external) and leaks. Dirt, bugs and debris
can block air flow through the core and reduce the radiator's ability
to dissipate heat.?
(..)
?If clogged, the radiator should be removed for cleaning or replaced.
Backflushing the cooling system and/or using chemical cleaners can
remove rust and hard water scale, but may do little to open up a
clogged radiator.?

COOLING SYSTEM
?Operating the engine with a thermostat stuck in the open position
or with the wrong thermostat installed, can cause the
engine to run too cool. This may reduce fuel efficiency by 7%.
Consult a repair manual or owners manual for proper cooling
system maintenance. Flush your systems at least every two
years to keep the water passages free of rust and corrosion.
Blocked passages reduce cooling efficiency by slowing the
movement of the coolant through the engine and radiator.?
