The Cool Hot Rod (1953)
Uses narration by a teen-ager to show how a hot-rod club contributes to
safe driving through its strict membership rules and restriction of speed
runs to 'DRAG STRIPS.'.

"A DRAMATIZATION OF THE COOLING SYSTEM OF THE AUTOMOBILE, SHOWING HOW THE
WATER CIRCULATES AROUND THE CYLINDERS, COOLING THEM AND IN TURN BEING
COOLED BY THE AIR DRAWN IN THROUGH THE RADIATOR."
Public domain film from the Library of Congress Prelinger Archive, slightly
cropped to remove uneven edges, with the aspect ratio corrected, and mild
video noise reduction applied.
The soundtrack was also processed with volume normalization, noise
reduction, clipping reduction, and equalization (the resulting sound,
though not perfect, is far less noisy than the original).
...Cars and trucks using direct air cooling (without an intermediate
liquid) were built over a long period from the very beginning and ending
with a small and generally unrecognized technical change. Before World War
II, water-cooled cars and trucks routinely overheated while climbing
mountain roads, creating geysers of boiling cooling water. This was
considered normal, and at the time, most noted mountain roads had auto
repair shops to minister to overheating engines....
... The subject of boiling engines was addressed, researched, and a
solution found. Previous radiators and engine blocks were properly designed
and survived durability tests, but used water pumps with a leaky
graphite-lubricated "rope" seal (gland) on the pump shaft. The seal was
inherited from steam engines, where water loss is accepted, since steam
engines already expend large volumes of water. Because the pump seal leaked
mainly when the pump was running and the engine was hot, the water loss
evaporated inconspicuously, leaving at best a small rusty trace when the
engine stopped and cooled, thereby not revealing significant water loss.
Automobile radiators (or heat exchangers) have an outlet that feeds cooled
water to the engine and the engine has an outlet that feeds heated water to
the top of the radiator. Water circulation is aided by a rotary pump that
has only a slight effect, having to work over such a wide range of speeds
that its impeller has only a minimal effect as a pump. While running, the
leaking pump seal drained cooling water to a level where the pump could no
longer return water to the top of the radiator, so water circulation ceased
and water in the engine boiled. However, since water loss led to overheat
and further water loss from boil-over, the original water loss was hidden.
After isolating the pump problem, cars and trucks built for the war effort
(no civilian cars were built during that time) were equipped with
carbon-seal water pumps that did not leak and caused no more geysers.
Meanwhile, air cooling advanced in memory of boiling engines... even though
boil-over was no longer a common problem. Air-cooled engines became popular
throughout Europe. After the war, Volkswagen advertised in the USA as not
boiling over, even though new water-cooled cars no longer boiled over, but
these cars sold well, and without question. But as air quality awareness
rose in the 1960s, and laws governing Exhaust emissions were passed, unleaded gas
replaced leaded gas and leaner fuel mixtures became the norm. These
reductions in the cooling effects of both the lead and the formerly rich
fuel mixture, led to overheating in the air-cooled engines. Valve failures
and other engine damage was the result. Volkswagen responded by abandoning
their (flat) horizontally opposed air-cooled engines, while Subaru took a
different course and chose liquid-cooling for their (flat) engines.
Today practically no air-cooled automotive engines are built, air cooling
being fraught with manufacturing expense and maintenance problems.
Motorcycles had an additional problem in that a water leak presented a
greater threat to reliability, their engines having small cooling water
volume, so they were loath to change; today most larger motorcycles are
water-cooled with many relying on convection circulation with no pump...
How a Differential Works and Types of Differentials
Video I created for Toyota in 2007. This was produced on a budget but its
purpose is to explain the concepts and not be a Pixar-budget film.

V12 Detriot Diesel 525HP
Setting the engine up and breaking it in.Remember this engine is just being
started after a rebuild so that's why it's smoking from the assembly lube
and the rack will be set-up to stop the hunting etc etc. Then the oil is
changed and the engine painted. These engine's go into Euclid mining rock
trucks,and they were in many other equipment/vehicles.The engine has
rebuild heads,turbo's, blower, water
pump,all internal parts and the air compressor All done in the great north

1905 Reid 15hp oilfield stationary engine
This is a 1905 Reid 15 hp engine that my Dad just rebuilt/restored. The
cart it sits on, He built himself from pictures. The rear wheels are made
from 30" pipe, and the fronts are 16". The frame is some left over I beam
and the steering is his own design.
The fuel is propane with a needle valve to regulate flow. The ignition is
some old military coil with a sparkplug screwed into an adapter in the head
that he made and a micro switch mounted on the base with a trigger mounted
to a disc bolted to the crank. The flyball gov. isn't connected yet, but it
will be soon to help control rpm.
How a 2 stroke detroit diesel engine runs
I have a couple videos of my 2 stroke detroit diesel powered pickup here on
youtube, and I have gotten hundreds and hundreds of questions about how in
the world it runs, and lots of people who do not believe that it really is
a 2 stroke. So, I'm sorry, I don't have the best voice in the world, and
I'm not the best at explaining things or getting the right words to come
out, but I did my best in this video to try to give you an idea of how it

Sit back for 10 minutes and enjoy ( PART 1) of some long lost commercials
of 1961 from Route 66. Many Chevolet Impalas, Biscayne, Brookwood Station
Wagon, Corvairs, Trucks, etc. Bayer Asprin and Philips Milk Of Magnesia, it
will surely bring back some great memories, it does for me!
