00:00:00.080 --> 00:00:02.230
- Alright, alright,
alright, alright, now Bart.
00:00:02.230 --> 00:00:03.150
Yeah?
00:00:03.150 --> 00:00:05.240
What's cooler than being cool?
00:00:05.240 --> 00:00:07.110
Ice Bart.
00:00:07.110 --> 00:00:07.956
Oh yeah.
00:00:07.956 --> 00:00:09.540
(electronic music)
00:00:09.540 --> 00:00:10.700
Hey there cool kids,
00:00:10.700 --> 00:00:13.230
today we're talking about
something I know a lot about,
00:00:13.230 --> 00:00:14.100
being cool.
(children cheering)
00:00:14.100 --> 00:00:15.650
If you're watching this,
00:00:15.650 --> 00:00:17.730
you probably already know how to be cool,
00:00:17.730 --> 00:00:19.100
but what about engines, huh?
00:00:19.100 --> 00:00:20.703
How can an engine be cool?
00:00:20.703 --> 00:00:22.703
Please tell me how to be cool
00:00:22.810 --> 00:00:25.930
Shut up, nerd engine,
you'll never be cool,
00:00:25.930 --> 00:00:27.310
you wear glasses.
00:00:27.310 --> 00:00:28.662
Now get out of here.
00:00:28.662 --> 00:00:30.910
Ugh, I'm sorry you had to see that folks.
00:00:30.910 --> 00:00:34.000
An internal combustion engine
is a lot like my inner thighs,
00:00:34.000 --> 00:00:35.170
it produces a lot of heat.
00:00:35.170 --> 00:00:36.670
You gotta keep engines from overheating
00:00:36.670 --> 00:00:39.220
and sometimes you gotta
keep them from freezing.
00:00:39.220 --> 00:00:43.060
Some people live in places
where it freezes, weird.
00:00:43.060 --> 00:00:44.160
In that case,
00:00:44.160 --> 00:00:48.180
you'd need something to
do the opposite of freeze,
00:00:48.180 --> 00:00:51.625
some sort of antifreeze.
00:00:51.625 --> 00:00:54.170
(man maniacally laughing)
00:00:54.170 --> 00:00:56.400
Antifreeze is also referred to as coolant
00:00:56.400 --> 00:00:57.600
when it's mixed with water
00:00:57.600 --> 00:00:59.910
if you're like me, you may
have thought that coolant
00:00:59.910 --> 00:01:02.200
referred to an ant that
has a bunch of tattoos.
00:01:02.200 --> 00:01:03.210
Well, it doesn't.
00:01:03.210 --> 00:01:04.050
Coolant is a liquid
00:01:04.050 --> 00:01:05.690
that prevents your
engine from overheating.
00:01:05.690 --> 00:01:06.523
Wait a minute,
00:01:06.523 --> 00:01:08.970
the same liquid can keep
your engine from overheating
00:01:08.970 --> 00:01:11.090
and keep your engine from freezing
00:01:11.090 --> 00:01:13.100
and make you go blind if you drink it?
00:01:13.100 --> 00:01:16.170
That sounds unpossible, but true.
00:01:16.170 --> 00:01:18.170
You could just use water
to cool your engine
00:01:18.170 --> 00:01:19.430
and it'd do a decent job
00:01:19.430 --> 00:01:21.810
but there are more than a few problems
00:01:21.810 --> 00:01:22.970
with relying on water.
00:01:22.970 --> 00:01:25.660
One, in extreme heat it boils over,
00:01:25.660 --> 00:01:28.080
it overheats and damages
the engine and two,
00:01:28.080 --> 00:01:30.210
in extreme cold, it freezes,
00:01:30.210 --> 00:01:31.990
expanding and breaking the engine.
00:01:31.990 --> 00:01:34.730
Antifreeze is a chemical mostly consisting
00:01:34.730 --> 00:01:36.120
of ethylene glycol
00:01:36.120 --> 00:01:39.130
or sometimes the lower
toxicity propylene glycol.
00:01:39.130 --> 00:01:41.890
When mixed with water it serves
to lower the freezing point
00:01:41.890 --> 00:01:43.810
and raise the boiling
point in the mixture.
00:01:43.810 --> 00:01:45.950
It also includes some corrosion inhibitors
00:01:45.950 --> 00:01:48.350
that are needed to
prevent rust from forming
00:01:48.350 --> 00:01:51.260
on the metal parts like water
pumps and engine blocks.
00:01:51.260 --> 00:01:53.530
When the antifreeze gets
brow or rusty in color
00:01:53.530 --> 00:01:55.590
that means the inhibitors are broken down
00:01:55.590 --> 00:01:56.423
and the antifreeze,
00:01:56.423 --> 00:01:58.570
now just like a pet dolphin that ran away,
00:01:58.570 --> 00:01:59.800
needs to be replaced.
00:01:59.800 --> 00:02:01.100
Antifreeze works because the
00:02:01.100 --> 00:02:03.120
freezing and boiling points of liquid
00:02:03.120 --> 00:02:05.160
are colligative properties,
00:02:05.160 --> 00:02:08.830
meaning they depend on the
concentrations of solutes
00:02:08.830 --> 00:02:10.760
or dissolved substances in the solution.
00:02:10.760 --> 00:02:13.840
A pure solution freezes
because the lower temperatures
00:02:13.840 --> 00:02:15.940
cause the molecules to slow down
00:02:15.940 --> 00:02:18.560
allowing the natural
attractive forces between them
00:02:18.560 --> 00:02:22.850
to capture and bind them into
rigid crystalline structures,
00:02:22.850 --> 00:02:25.450
but adding a different
kind of molecule to the mix
00:02:25.450 --> 00:02:27.460
blocks those attractive forces
00:02:27.460 --> 00:02:29.970
and prevents the crystalline
structures from forming.
00:02:29.970 --> 00:02:31.890
The more solutes that are added,
00:02:31.890 --> 00:02:33.490
the lower the temperature needs to be
00:02:33.490 --> 00:02:36.210
before the solution can properly freeze.
00:02:36.210 --> 00:02:37.580
If you're confused, don't worry,
00:02:37.580 --> 00:02:40.540
so am I, all the time, about everything.
00:02:40.540 --> 00:02:42.630
Why am I being filmed?
00:02:42.630 --> 00:02:43.900
See when water freezes,
00:02:43.900 --> 00:02:46.330
it crystallizes and expands like your mom.
00:02:46.330 --> 00:02:48.310
When water had something dissolved in it,
00:02:48.310 --> 00:02:50.510
the molecules have to work more
00:02:50.510 --> 00:02:52.390
to get near each other to crystallize.
00:02:52.390 --> 00:02:55.930
That extra work to crystallize
drops the freezing point.
00:02:55.930 --> 00:02:58.980
That's why road salt works,
it dissolves in water
00:02:58.980 --> 00:03:00.630
or on contact with snow or ice,
00:03:00.630 --> 00:03:03.350
and if it dissolves, it
breaks up the crystals
00:03:03.350 --> 00:03:05.300
and makes the crystals harder to form,
00:03:05.300 --> 00:03:07.560
but salt, even when dissolved in water,
00:03:07.560 --> 00:03:10.360
can still be hard enough
that when they shoot around
00:03:10.360 --> 00:03:13.070
in a closed system like your
engine, they could do damage.
00:03:13.070 --> 00:03:14.900
Ethylene glycol works great
00:03:14.900 --> 00:03:17.200
'cause not only is it water soluble,
00:03:17.200 --> 00:03:18.920
it's what we call miscible,
00:03:18.920 --> 00:03:21.700
which means it can be
mixed with any amount
00:03:21.700 --> 00:03:23.130
and still mix evenly.
00:03:23.130 --> 00:03:25.550
Antifreeze and water should
have a mixture percentage
00:03:25.550 --> 00:03:27.180
based on the lowest temperatures
00:03:27.180 --> 00:03:28.540
typically seen in your climate.
00:03:28.540 --> 00:03:31.770
In most regions, these are
50-50 water-antifreeze mixture
00:03:31.770 --> 00:03:33.850
which will provide sufficient protection
00:03:33.850 --> 00:03:37.430
from little below freezing
to a high of 265 degrees.
00:03:37.430 --> 00:03:38.740
In the coldest temperatures,
00:03:38.740 --> 00:03:42.070
you could use a mix of
60 to 70% antifreeze.
00:03:42.070 --> 00:03:44.830
The color of antifreeze
is from a coloring dye.
00:03:44.830 --> 00:03:47.410
Not just the chemical
used but specific colors
00:03:47.410 --> 00:03:49.980
often mean something differently
in the chemical makeup.
00:03:49.980 --> 00:03:51.960
The main antifreeze
colors that you run across
00:03:51.960 --> 00:03:54.410
are the tradition green
and extended-life yellow
00:03:54.410 --> 00:03:56.310
and extended-life pink or orange.
00:03:56.310 --> 00:03:57.850
Antifreeze has got a specific color
00:03:57.850 --> 00:04:00.440
and that's so if it's
leaking, you know what it is.
00:04:00.440 --> 00:04:02.440
Now to see how that
antifreeze gets around,
00:04:02.440 --> 00:04:03.960
let's go inside the engine.
00:04:03.960 --> 00:04:06.120
- You wanna go inside of me?
- What?
00:04:06.120 --> 00:04:08.890
No, shut up nerd engine
and get out of here
00:04:08.890 --> 00:04:10.810
before I blow you up.
00:04:10.810 --> 00:04:13.080
Sorry gang, I gotta
take care of that engine
00:04:13.080 --> 00:04:14.510
like I took care of Mr. Carburetor
00:04:14.510 --> 00:04:16.200
when I found out he stole my kidney.
00:04:16.200 --> 00:04:17.120
You think I wouldn't find out, huh?
00:04:17.120 --> 00:04:18.893
- Calm down, Bart, we can talk about this.
00:04:18.893 --> 00:04:22.155
(thudding)
(metal clanking)
00:04:22.155 --> 00:04:24.773
Oh, what are you, please, times are tough.
00:04:24.773 --> 00:04:25.728
Please, oh.
00:04:25.728 --> 00:04:27.978
00:04:29.685 --> 00:04:31.060
I'm sorry.
00:04:31.060 --> 00:04:34.060
(Carburetor crying)
00:04:35.544 --> 00:04:36.377
00:04:38.940 --> 00:04:40.240
- Coolant flows through a path
00:04:40.240 --> 00:04:41.930
that takes it from the water pump
00:04:41.930 --> 00:04:44.210
through the passages
inside the engine block
00:04:44.210 --> 00:04:46.970
where it collects more heat
produced by the cylinders.
00:04:46.970 --> 00:04:49.660
It then flows up to the cylinder head,
00:04:49.660 --> 00:04:51.220
or heads in a V type engine,
00:04:51.220 --> 00:04:54.380
from the combustion chambers,
00:04:54.380 --> 00:04:57.160
then it flows out past the thermostat,
00:04:57.160 --> 00:04:59.470
if the thermostat's
opened up to let it pass,
00:04:59.470 --> 00:05:02.140
through the upper radiator
hose and into the radiator.
00:05:02.140 --> 00:05:05.410
Here the coolant flows through
the thin flattened hoses
00:05:05.410 --> 00:05:07.120
that make up the core of the radiator
00:05:07.120 --> 00:05:10.870
and it's cooled by the air
flow across those vents.
00:05:10.870 --> 00:05:12.610
The coolant flows out of the radiator,
00:05:12.610 --> 00:05:14.450
through the hose and
back to the water pump,
00:05:14.450 --> 00:05:16.180
by this time cooled off
00:05:16.180 --> 00:05:18.890
and ready to go grab more
heat from the engine.
00:05:18.890 --> 00:05:21.720
A car's water pump's used to
send fluid to the engine block.
00:05:21.720 --> 00:05:24.230
It's a simple centrifugal
pump driven by a belt
00:05:24.230 --> 00:05:25.887
connected to the crankshaft of the engine,
00:05:25.887 --> 00:05:27.970
and that uses centrifugal force
00:05:27.970 --> 00:05:30.170
to send the fluid outside while it spins,
00:05:30.170 --> 00:05:32.880
making it drawn in from
the center continuously.
00:05:32.880 --> 00:05:35.360
The inlet of the pump is
located near the center
00:05:35.360 --> 00:05:37.510
so the fluid returning from the radiator
00:05:37.510 --> 00:05:38.850
hits these pump veins.
00:05:38.850 --> 00:05:41.400
Pump veins fling the fluid
to the outside of the pump
00:05:41.400 --> 00:05:42.780
where it can enter the engine in there,
00:05:42.780 --> 00:05:44.620
makes it way through all those passages
00:05:44.620 --> 00:05:46.030
in the engine and the cylinders
00:05:46.030 --> 00:05:48.435
where it returns to the
cylinder head of the engine.
00:05:48.435 --> 00:05:51.330
Thermostat's located where
the fluid leaves the engine.
00:05:51.330 --> 00:05:53.120
The plumbing around the thermostat
00:05:53.120 --> 00:05:55.540
sends the fluid back to the pump directly
00:05:55.540 --> 00:05:56.880
if the thermostat's closed.
00:05:56.880 --> 00:06:00.060
If it's open, the fluid goes
through the radiator first
00:06:00.060 --> 00:06:00.893
and then back to the pump,
00:06:00.893 --> 00:06:03.270
thermostat's regulating
the amount of water
00:06:03.270 --> 00:06:04.660
that goes through the radiator.
00:06:04.660 --> 00:06:06.150
Nowadays a lot of these mechanisms
00:06:06.150 --> 00:06:07.400
are controlled by computers
00:06:07.400 --> 00:06:09.460
but the secret to the
thermostat used to lie
00:06:09.460 --> 00:06:10.500
in a small cylinder
00:06:10.500 --> 00:06:12.430
located in the engine side of the device.
00:06:12.430 --> 00:06:14.120
The cylinder is filled with a wax
00:06:14.120 --> 00:06:17.650
that begins to melt at around
180 degrees Fahrenheit.
00:06:17.650 --> 00:06:20.440
A rod connected to the
valve presses into the wax
00:06:20.440 --> 00:06:23.010
and when it melts, it expands a bunch,
00:06:23.010 --> 00:06:26.560
pushing the rod out of the
cylinder and opening the valve.
00:06:26.560 --> 00:06:29.078
That's how turkey thermostats work.
00:06:29.078 --> 00:06:29.911
Bing.
00:06:29.911 --> 00:06:31.390
Life hack, if you wanna reuse them,
00:06:31.390 --> 00:06:32.440
put a rubber band around them
00:06:32.440 --> 00:06:33.470
and let it cool off in your fridge
00:06:33.470 --> 00:06:35.210
and then you stick it in
whatever turkeys you want.
00:06:35.210 --> 00:06:36.350
How many turkeys are you cooking?
00:06:36.350 --> 00:06:38.840
None, one a year, and you
probably did it wrong.
00:06:38.840 --> 00:06:41.480
The radiator essentially takes
the heat from the coolant
00:06:41.480 --> 00:06:42.820
and gives it to the air.
00:06:42.820 --> 00:06:45.680
Most modern cars use aluminum radiators.
00:06:45.680 --> 00:06:48.550
They're made by brazing thin aluminum fins
00:06:48.550 --> 00:06:49.930
to flattened aluminum tubes.
00:06:49.930 --> 00:06:52.210
The coolant flows from
the inlet to the outlet
00:06:52.210 --> 00:06:55.010
through all of these tubes
mounted in parallel arrangement.
00:06:55.010 --> 00:06:56.830
Fins conduct the heat,
00:06:56.830 --> 00:06:59.270
transfer it to the air
flowing through the radiator.
00:06:59.270 --> 00:07:02.680
Sometimes these tubes got a fin
inserted called a turbulator
00:07:02.680 --> 00:07:04.810
which is what I'm gonna name my first kid.
00:07:04.810 --> 00:07:07.170
The turbulator increases
the turbulence of the fluid
00:07:07.170 --> 00:07:08.530
flowing through the tubes.
00:07:08.530 --> 00:07:10.580
If the fluid flowed evenly,
00:07:10.580 --> 00:07:12.580
only the stuff actually touching the tube
00:07:12.580 --> 00:07:13.640
would be cooled directly.
00:07:13.640 --> 00:07:15.290
When you create that turbulence,
00:07:15.290 --> 00:07:16.802
more fluid is getting cooled.
00:07:16.802 --> 00:07:18.800
Crazy, you guys are so smart.
00:07:18.800 --> 00:07:20.540
This means more heat's extracted
00:07:20.540 --> 00:07:23.400
and all the fluid inside the
tube is used effectively.
00:07:23.400 --> 00:07:25.700
All this talk of fluid in tubes
00:07:25.700 --> 00:07:27.980
reminds me of the lab
where I was conceived.
00:07:27.980 --> 00:07:30.380
Now, the radiator cap itself
00:07:30.380 --> 00:07:33.210
actually increases the
boiling point of your coolant
00:07:33.210 --> 00:07:34.850
by about 45 degrees.
00:07:34.850 --> 00:07:36.710
Works the same way a pressure cooker
00:07:36.710 --> 00:07:38.130
prevents water from boiling.
00:07:38.130 --> 00:07:40.530
The cap is actually a
pressure release valve
00:07:40.530 --> 00:07:43.270
and on cars it's usually
set to about 15 PSI.
00:07:43.270 --> 00:07:45.320
The boiling point of water increases
00:07:45.320 --> 00:07:47.300
when the water is placed under pressure.
00:07:47.300 --> 00:07:50.060
It's got no where to
expand and turn into gas.
00:07:50.060 --> 00:07:52.950
Water below sea level
boils at higher temperature
00:07:52.950 --> 00:07:55.370
'cause it's under more
pressure from the atmosphere.
00:07:55.370 --> 00:07:57.000
When the fluid in the
cooling system heats up,
00:07:57.000 --> 00:07:58.840
it expands, so the pressure builds.
00:07:58.840 --> 00:08:01.290
The cap is the only place
where this pressure can escape
00:08:01.290 --> 00:08:03.900
so the setting of the
spring on the cap determines
00:08:03.900 --> 00:08:05.980
the maximum pressure
in the cooling system.
00:08:05.980 --> 00:08:07.910
When the pressure reaches that point,
00:08:07.910 --> 00:08:09.380
it pushes the valve open,
00:08:09.380 --> 00:08:11.730
allowing coolant to escape
from the cooling system
00:08:11.730 --> 00:08:13.780
and keeping the pressure
where it should be.
00:08:13.780 --> 00:08:16.200
The coolant flows
through the overflow tube
00:08:16.200 --> 00:08:18.150
into the bottom of the overflow tank.
00:08:18.150 --> 00:08:20.477
This arrangement keeps
air out of the system,
00:08:20.477 --> 00:08:22.320
and when the radiator cools back down,
00:08:22.320 --> 00:08:24.110
it creates a vacuum in the cooling system,
00:08:24.110 --> 00:08:26.460
pulls open another spring
in the loaded valve,
00:08:26.460 --> 00:08:28.440
and that sucks water back in
00:08:28.440 --> 00:08:30.090
from the bottom of the overflow tank
00:08:30.090 --> 00:08:31.890
to replace the water that was expelled.
00:08:31.890 --> 00:08:35.270
Used to be you just had a big
old fan driven by the engine
00:08:35.270 --> 00:08:36.690
cooling all of this off,
00:08:36.690 --> 00:08:39.750
but nowadays the cooling
fan is controlled externally
00:08:39.750 --> 00:08:41.770
to maintain a constant engine temperature.
00:08:41.770 --> 00:08:44.440
Some fans are controlled either
with a thermostatic switch
00:08:44.440 --> 00:08:45.420
by the engine computer
00:08:45.420 --> 00:08:47.590
and they turn on when the
temperatures of the coolant
00:08:47.590 --> 00:08:48.940
gets above a set point,
00:08:48.940 --> 00:08:51.580
and turn back off when the
temperature drops below.
00:08:51.580 --> 00:08:54.410
There's also a separate
circuit for the heating system.
00:08:54.410 --> 00:08:56.810
This circuit takes fluid
from the cylinder head
00:08:56.810 --> 00:08:59.410
and passes it through a heater
core, then back to the pump.
00:08:59.410 --> 00:09:02.140
Heater core, located in
the dashboard of your car,
00:09:02.140 --> 00:09:04.200
is really a little tiny radiator.
00:09:04.200 --> 00:09:06.520
The heater fan blows the
air through the heater core
00:09:06.520 --> 00:09:08.270
into the passenger compartment of your car
00:09:08.270 --> 00:09:09.410
and keeps you warm.
00:09:09.410 --> 00:09:12.150
The heater core draws it's
coolant from the cylinder head
00:09:12.150 --> 00:09:14.870
and returns it to the pump,
so it works regardless
00:09:14.870 --> 00:09:16.590
if the thermostat's open or closed.
00:09:16.590 --> 00:09:19.310
If your car is overheating,
you can turn on the heater
00:09:19.310 --> 00:09:22.350
and it can pull hot air
from the engine compartment
00:09:22.350 --> 00:09:24.092
and cool off your engine.
00:09:24.092 --> 00:09:26.090
I'm sorry everybody, I
can't do this anymore,
00:09:26.090 --> 00:09:27.340
I got a confession to make.
00:09:27.340 --> 00:09:28.630
It's something I've been hiding
00:09:28.630 --> 00:09:29.970
for at least several minutes.
00:09:29.970 --> 00:09:31.040
Well, here it goes.
(dolphin chirps)
00:09:31.040 --> 00:09:33.540
Liquid is not the only
way to cool an engine
00:09:33.540 --> 00:09:35.670
and I created a human
dolphin hybrid in the lab.
00:09:35.670 --> 00:09:38.110
Oh, it feels so good to get off my chest.
00:09:38.110 --> 00:09:39.837
So yeah, there's liquid cooled engines
00:09:39.837 --> 00:09:41.110
and air cooled engines.
00:09:41.110 --> 00:09:42.770
Technically, all engines are air cooled
00:09:42.770 --> 00:09:46.070
because even water cooled engines
use air to cool the water.
00:09:46.070 --> 00:09:47.240
Mind-blowing right.
00:09:47.240 --> 00:09:49.610
Well, pick your jaws up off
the floor and I'm gonna go on.
00:09:49.610 --> 00:09:52.850
Air cooled engines have fins extending out
00:09:52.850 --> 00:09:53.930
that pull heat away.
00:09:53.930 --> 00:09:57.250
Cool air is forced over the
fins typically by a fan.
00:09:57.250 --> 00:10:00.740
Those air cooled Porsches and
VW engines were boxer engines
00:10:00.740 --> 00:10:04.200
because they can expose
more surface area to the air
00:10:04.200 --> 00:10:05.160
to cool 'em off.
00:10:05.160 --> 00:10:06.830
The explosions in the chamber
00:10:06.830 --> 00:10:09.770
aren't serving to warm up
a huge solid engine block,
00:10:09.770 --> 00:10:11.530
just their own chambers.
00:10:11.530 --> 00:10:14.250
Also, they've got what
amounts to essentially a fan
00:10:14.250 --> 00:10:16.480
in the engine to pull air through,
00:10:16.480 --> 00:10:18.910
and those crazy, distinctive
holes in the back
00:10:18.910 --> 00:10:21.630
and all around those old
Porsches and Bugs and vans,
00:10:21.630 --> 00:10:24.940
well they're there to let
as much air as possible in
00:10:24.940 --> 00:10:27.370
so that it can get around
and through the engines.
00:10:27.370 --> 00:10:31.150
So, if there's enough air
flow, those dang ol' engines,
00:10:31.150 --> 00:10:32.670
they're gonna last just about forever.
00:10:32.670 --> 00:10:36.090
These days air cooled engines
mostly show up in motorcycles,
00:10:36.090 --> 00:10:38.810
all-terrain vehicles, riding
lawn mowers and aircraft.
00:10:38.810 --> 00:10:40.520
Personally I got an air cooled engine
00:10:40.520 --> 00:10:43.240
in my all-terrain riding
law mower helicopter cycle.
00:10:43.240 --> 00:10:44.080
Join us n...
00:10:45.430 --> 00:10:46.860
Who are you?
00:10:46.860 --> 00:10:49.070
- It's me, Bart, nerd engine.
00:10:49.070 --> 00:10:51.260
Turns out I was just overheating.
00:10:51.260 --> 00:10:54.050
I put some coolant up inside me and boom,
00:10:54.050 --> 00:10:56.983
my glasses fell off and now I'm cool.
00:10:58.050 --> 00:11:00.610
- Boy, I'll say you are.
00:11:00.610 --> 00:11:03.690
You're the coolest engine I've ever seen.
00:11:03.690 --> 00:11:04.880
Say nerd engine.
00:11:04.880 --> 00:11:06.310
- Yes, Bart.
00:11:06.310 --> 00:11:09.470
- Do you maybe wanna go to prom with me?
00:11:09.470 --> 00:11:11.430
- I thought you'd never ask.
00:11:11.430 --> 00:11:12.597
- Woo-hoo-hoo!
00:11:13.550 --> 00:11:15.070
Cooling an engine!
