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! 00:11:15.070 --> 00:11:17.280 Click the yellow button to subscribe to Donut, 00:11:17.280 --> 00:11:19.180 we got new shows coming out every day, 00:11:19.180 --> 00:11:20.780 you don't wanna miss a thing. 00:11:20.780 --> 00:11:23.160 Oh, check Nolan's WheelHouse on air cooled Porsches. 00:11:23.160 --> 00:11:24.720 Check out this episode of Hot Lap. 00:11:24.720 --> 00:11:27.410 Follow us on Twitter and Instagram @donutmedia. 00:11:27.410 --> 00:11:29.110 Follow me @bidsbarto. 00:11:29.110 --> 00:11:30.600 Got to shop.donut.media, 00:11:30.600 --> 00:11:33.690 we come up with a new piece of merchandise every dang week. 00:11:33.690 --> 00:11:36.190 Don't tell my wife I'm taking nerd engine to prom.
