Changing a Radiator on an EMD SD 40-2 Locomotive 

Check out my other You Tube channel with more cool railroad and rail fanning videos along with other adventures Dave has: www.youtube.com/@ThatsDavesOtherDoings

Wow Dave, you really are a master of all trades! From banging spikes, welding rails, tamping ballast to fixing locos! That start up sounded pretty cool. Good job!

From the Technical Data Sheet for the 810-S Sticks: 810S is a multi-metal safe corrosion inhibitor for use in diesel engine cooling systems to protect from premature failure due to corrosion. 810S is packaged as a stick capable of being easily and safely added directly into filler necks of cooling water systems. 810S dissolves quickly in warm water and will not freeze in cold weather months. One box is sufficient to treat any common locomotive cooling system (275-350 gallons).

Good job replacing both of the radiator's. It will save time in the future. Thanks for sharing Dave. Good call on checking for leaks before dropping the fan sections in place.

I would like to see You and Danny Harmon of Distant Signal get together and record an old fashioned Pow Paw. Two of my favorite railroad RU-vidrs.

Now that is something you don't see...........sometimes ever! Nice

That's a great opening shot, foggy with loco over your shoulder.

Always love getting up close with 3098. I'm very glad that the mechanics took your advise about leaving the top cover off until the system was full so they could check for leaks. Wow upper 30's in the morning!? That must be nice. Still waiting for it to cool off here in Dallas.

"Raddiater", love it. Looks like you have a great team with the right equipment. At IRM we used to have one of those compressors running off of a trolley traction motor for air for the steam shop. Since IRM started as a traction museum 600 VDC was always present. I'm with you on the two new ones right away. Great video, thanks Dave!

thanks for another great video dave , at least you had a good day to change out them radiators and that was a beautiful sound when the locomotive started up !

Thanks Dave your awesome, really appreciate you taking us along on these repair jobs, im with you on putting 2 new halves in, and was good to see they did that.. always cool seeing the inner workings of the locos, and thanks for showing the fire suppression.. Good stuff

Good morning. Great video. I love how you take us inside the locomotive to see the inner workings. Have a great day Dave.

I love these looks behind the scenes Dave. Learn something new with every presentation. I love the sound of those big EMDs being fired up.

Looks like a fun task to me. Thanks for sharing, Dave. Time to break out the winter clothes too, hey!

Thank you for sharing with us Dave, that was very interesting! It would be kind of scary to have a radiator leak with such a huge water capacity.

Well, Dave, once again you knock it out of the park great video , the one thing I would mention is the reason they don’t shut off the locomotives because of NO Antifreeze in the cooling system👍🏻👍🏻🚂🚂

😊 Several points of interest new to me, learned. Thanks Dave -- as cheerful as ever!

I work in hazardous material transportation , the 8 is the hazard class. In this case 8 is a corrosive.....the III is the packing group identification. The EGR number is the page number where all of the hazard information for the product can be found in the Emergency Response Guide handbook.

Always interesting to see the workings of these locos. Thanks for sharing, Dave.

Another project completed..Thanks Dave

Can't see the Model T trick putting an egg in the rad working on that puppy😂. Great video Dave👨‍🔧👨‍🔧👨‍🔧👷‍♂️🚂🇨🇦🇺🇲

Dave: As usual, your videos are intense and excellent! Love all the details (the V_shape, and the radiator close ups...all superb!)

Thanks for the tour. You make a good docent. Later.

Another project completed. Great Video.

That air compressor looks mighty clean. That chemical has hundreds of uses, one being a corrosion inhibitor.

It should be noted there are several reasons locomotives don't use antifreeze. 1 reason is if there is a leak in the engine (and yes there are leaks in EMDs, they always leak) itself, antifreeze will mix with the oil and ruin the oil and cause the bearings to seize. Raw water will not mix with oil and will evaporate causing no damage to the engine. 2 reason is EPA and costs. Aside from destroying locomotive engines, leaks and other accidents can create environmental hazards and this can lead to fines being levelled against the railroad owners as well as destroying natural habitats for the little duckies.. As for the water freezing in the motor; Most locomotives run contiguously 24 hours a day. I don't know about Daves loco's though. When the locos are shut off, the water system is protected by an Ogontz valve under frame that stays warm as long as water is circulating, if engine stops for some reason the Ogontz valve cools off and dumps water if temp drops below 50 degrees. This valve protects the engine from freezing. The only additive in the water is a corrosion inhibitor (pink stuff) which is not harmful to the environment and acts as a rust inhibitor and also protects the delicate radiators from contaminants in the water. The pink sticks are a chromate compound. How many need to be used will depend on the manufacturer's recommendation. Further, locomotive engines cooling system is designed different from a passenger car and is not a closed system as found in passenger cars. Closed systems found in cars do need antifreeze to keep the water from boiling and turning to steam in the closed system. This is not an actual problem with locomotive cooling systems. The engines in these EMDs tend to run slightly cooler than passenger cars. And last, as Dave said, straight water cools better overall so it's more efficient. All these things keep the loco happy and a happy loco means Dave is happy.

I love this channel. I have never worked on the railroad. But I come from a family of railroad men. My grandfather worked for the MKT his brother worked for the Missouri Pacific railroad. And I had an uncle that worked for the Southern Pacific railroad. And I love railroad history!

Thanks Dave this was interesting to watch. I do enjoy your videos always good content. Happy rails to you.

Blessed October, Buddy! Now that you are back in pictures, it is time to get America back into training!

The "PGIII" is actually PG"3" using roman numerals. It's "Packing Group 3", has to do with hazmat. It's a classification system to show the level of danger of the items being shipped. 1 being very dangerous, 3 low danger. So of you've gone through hazmat training, and know what all that means, it actually does say a lot. But gibberish to anyone who hasn't.

Hiya Dave Good seeing you Stay safely blessed brother Thank you for sharing

Very radiant.

Tks for sharing Dave!

Very cool, Dave! You're always bringing us something unique we otherwise wouldn't get to see

Another fantastic video Dave. I watched your frog video today on YT TV

Loved the video Dave. EMDs all the way. Enjoyed the video and have a wonderful upcoming Thursday.(Steve)

Really enjoyed this one Dave A lovely start up sound at the end too. I would of said change both rads. and fill them to check all is well too. You are a wise man job would of taken a lot longer if there had been a leak and they had not taken your advice.

Very nice video, as usual. I sure am glad they put both radiators for that side in! Those fans are huge, but looking at the engine that needs the cooling, no real surprise there. Do the fans ever seize up? (No sir, NOT borrowing trouble!) Glad they took a listen to ya for the fill-up! Good day for the work, too. Thank you for the video!

Very cool stuff that's railroading

Enjoyed the video Dave and moving coal is a great thing.

That prime mover is music to my ears.

That is some serious cooling capacity.. No lifting eyes.. make 'em. OK odd question. What's the attachment on the nose on #22s forward raining that kinda looks like an antenna mast?? Thanks for another peek inside rail operations..

Thank you for this video! Na₂SiO₃ - sodium silicate - for some reason called sodium meta silicate, but like sodium carbonate (washing soda) if the Si is replaced with a C. Carbon is just above silicon in the 14th group of the periodic table. Both are tetravalent and silicon has been proposed in both science fiction and science speculation as a substitute for carbon. That's railroadin'!

Hi Dave & it's is Randy and i like yours video is Cool & Thanks Dave & Friends Randy

Great video thank you

What a air compressor, no wonder trains never have flats.😂

We never used straight water when I worked for the railroad. They always used some kind of treatment that made it a reddish color.

Thumbs up 👍

Of course I got curious about the Disodium Trioxsilicate so I hade to check it up. First suprise... it's also known as "WaterGlas" which I heard is also used for treatment of concrete surfaces. But further googling and reading was indeed a wealth of knowledge. Sorry for the huge wall of text, but I found it all interesting: Sodium metasilicate is widely used in various types of washing industry. In the washing industry, such as super concentrated detergent, laundry detergent, laundry cream, dry cleaning agent, fiber bleach, fabric bleach, etc., also a large number of used for metal surface cleaning agent, beer bottle, aerosol detergent, after fully dissolved, it can be used as metal rust inhibitor, scale cleaning agent and electric device cleaning agent, and can be used as food industry detergent. It can also be used as mud consistency regulator and mud coagulant in crude oil and natural drilling and excavation engineering; in the construction industry, it is used as a coagulant for preparing acid-resistant mortar, acid-resistant commercial concrete and cement; In the paper industry, it can be used as an adhesive, an ink agent, and a paper surface treatment agent; in the textile industry as a printing and dyeing auxiliaries, fabric pre-treatment agent; Can also be used as soap filler, detergent, egg preservative, and vegetation molecular sieve, silicic acid and fire materials. Sodium metasilicate has lubricity, can be used for the production of ceramic body mud; With strong alkalinity, strong decontamination ability, large buffer capacity, can neutralize acidic dirt. Emulsification of fat and oil, has anti-flocculation effect on inorganic substances, has anti-corrosion effect on metals, so it is one of the main components of super concentrated detergent powder, and is also used in dishwashing detergent, food industry detergent, metal detergent and waste paper deinking. And by the way.. thanks for a nice tour of the locomotive.

Always interesting!

Excellent video, again. At 15:51 we see # 22 coming. This locomotive has a post on the front with somethings on top, do you now what that is? It looks like there are some electrical cables to it. Are they some kind of antennas?

2 new halves would be best thing. New wine in old wineskin parable comes to mind.

What is the debris at the bottom of the radiator V? Is that just leaves or is there coal in there too?

There’s a You Tube video called What in blazes made in the early 50s for PRR that shows fire suppression systems on F units and ALCo cab units. Give it a watch.

I can't wait for it to be in the 30's in the morning, we are still in the high 60's warming to almost 100 still 🥵

Hey Dave !!! NO antifreeze ?? Do they run the engines 24/7 in winter with NO shutdown ??? Thanks for the videos too !!! 👍👍👍👍👍

I really did enjoy the show. It was a good look into the radiators on a locomotive. Is the water pump engine driven or is it a stand alone unit? Thanks for the tour Dave.

Made in Seymour, Indiana. Down South. Did You ever find out how many sticks to the gallon?🤔

Cool.

what keeps the water from freezing during the wintertime?

How do these radiators go bad? Do they get clogged up or just start leaking? I ask because they look like heavy duty. Copper or aluminum units? Also, at what pressure do they run at and do they use an antifreeze as part of the cooling system? Thank you for your informative videos and a hello from San Antonio, TEXAS!

Are the cooling fans electric powered or are they mechanically shaft driven (I think I saw what looks like a drive shaft system lying along the bottom V part of where the radiators are placed. Thanks!

Dave what’s your plan on retirement or it’s not going happen?

That was some little warning label to find...after handling the material. But what can you do? I was just telling my wife one day ago, that it seems mechanics live to ripe old ages and don't stop. You see old rusty mechanics and they may slow down but they just keep going. It must be the chemicals.

Will be 72 tomorrow (10th), I welcome a new video from Dave. Help me celebrate by learning more about locomotive maintenance!!

Dave, how do you keep the water from freezing with no antifreeze in it? And, are the engines made by Detroit? They sure sound like Detroits.

So technically the locomotive is a SD40.2 (with no dash) 😅

Big boy radiator

Dave, can I send the new mic to 855 Kirby Rd, Waynesburg, PA 15370 And put it to your attention ? Or is there a better address ? Just power off the radio before you swap the mics. Should be plug and play. Exact part for the radio.

I am wondering what keeps the water in the radiators from freezing if they don't add antifreeze.

Doesn't the water freeze in the winter or do yall winterize them?

disodium trioxosilicate is a boiler water anti-corrosion chemical. It is a corrosive chemical to human skin. PGIII is Packing Group 3. For DOT shipping purposes. Identifies how it is to be packed. What modes of transportation and quantities that can be shipped, etc. I used to work in Environmental and Safety. The little orange book carried by firemen is used to identify it by the UN number.

It says one box (30 sticks) for one locomotive (275-350 gallons)

How do they keep the water in the radiator from freezing in the winter.

How that storm affect you guys?

Which way does the fans pull the air through the radiators. Does it pull the air through the radiators then out the top. Or the other way

sir did someone use some hardening products where the leak is

👍👍

ok there u go ,,,, how bout that,,,,,,

Rad iator or Raid iator? 😊

I think I Know what's wrong. It's broke. lol

Not meaning to be picky but you mispronounce radiator. It is not pronounced rad but ray. Ray- di- a-tor. You can look it up and you will see the correct pronunciation is as I have written it for you.
