Glad to have this job done! Plenty more that I need to fix...it never ends! Many people have posted links to an operator's manual that is online for a VIO50-6. Unfortunately, that is a different machine and doesn't apply to mine. Thanks for giving it a try though! I also agree that the drain setup would be fine with regular maintenance, but disagree with the design because that's a big if. I would design things assuming the real world, where things are going to get neglected. I've worked on many cars and trucks, and their coolant has been sitting for many years, but have never had a problem draining the radiator. There's no reason to put that silly 1/4" hose permanently attached at the bottom when I can easily reach the bottom of the radiator. Even worse that the fitting the hose terminates in has a hard 90 degree bend, so you can't run a wire through it without taking it apart like I did. I tried to blow 120PSI air through it, no go. Just put a drain valve on the bottom like vehicles have, and let the mechanic put a hose on it if they want to. My $0.02. Have an awesome weekend everybody!

Please read my comment on coolant for diesel engines. Does this engine require a diesel coolant with anti-cavitation additives?

‘I can’t get both hands on it at once’ 13:03 , surely there’s a that’s what she said joke in there 😂. But seriously, they could take a cue from Sany, my SY16C with a Yanmar engine, when you open the rear door to the engine compartment, there is a vertical hose hanging from a ball valve right in front of you that you can pull out and put straight into a container to drain the coolant. No tools, no fuss and you don’t even need to crouch down. 😊

John, I have to say your Yanmar excavator has made for some of the best content yet on KZread. Your attention to detail, and your continued energy to make things right continue to impress me. While you think you are done on the Yanmar, I would LOVE to see you repaint and re-decal it!! Thank you for showing us the proper way to work, and succeed.

He did say "he's pretty particular". It's due for a cosmetic freshen now!

Back when I used to service large generators cascade was the go to. We'd dump a whole big bottle of the liquid cascade into a 170 gallon cooling package, top it off with water and run it under load for about an hour. After that flush it a few times with pain water then fill with coolant. The amount of crud that came out was always pretty impressive. The lemon scented variety is my favorite lol.😂

Yanmar did a great job with the coolant drain. Easy location, just unscrew the drain plug. The problem is someone poured a lot of water in the system and it rusted. With proper antifreeze the drain will never clog. I always make mine to the Alaska concentration for extra corrosion protection.

I think the hose is a pretty good setup considering the space limitations of the fuel tank being directly under the radiator, I would drain a little bit of coolant out of it once a year and top it off just to keep the hose clear.

@Whittigo

6 ай бұрын

Yeah, having worked only on cars the hose and plug setup seems like the best solution compared to having to drag a hose around off to the side. But I agree with the potential for clogging, so a little routine maintenance once a year is probably what the engineers who designed it had in mind. But taking a step back into the real world, ain't nobody got time for that, and its going to get clogged again.

the only problem is whoever filled that cooling system with well water. yanmar did a great job putting that service bib there. the previous owners were Stupid and Lazy. And that is the only problem with this machine.

Let me recommend TSP - Tri Sodium Phosphate when flushing cooling systems. It USED to be in dishwasher detergent but was removed for environmental reasons. Its easy enough to buy a tub from Grainger and works even better than the cascade you used. Both together is the best. I flush old cooling systems all the time at work and use it every time.

Man, this makes me thankful to have had larger equipment... generally more room to work.

John, we're all really waiting for the pond update.

I purchased a 2000 Dodge Dakota in 2005. I noticed it would gradually heat up after a short amount of city driving. The coolant looked like yours. I purchased a radiator and went to replace it. The truck had 80000 miles. I noticed the water pump was an original part so I decided to change it. I removed the water pump and got the 8th wonder of the free world. The water pump impeller had rusted off the water pump.....new radiator, new water pump and flush flush flush. It never overheated again after the repair. Great video.

Man all the things your doing to this excavator , thing is brand new. Refresh the paint and be styling

Great repair, John. Unfortunately, buying used means doing all of the maintenance that the previous owners neglected. I must say, that stump removal was really anticlimactic. I was really hoping it would put a fight! 🤣

Dude I felt the same way. It just disintegrated and made me sad.

One of the things my old man always did and told me, when your done with the equipment at the end of the day always fill-up the tanks check the oil and other fluids. It was mainly to prevent condense to get into the fuel tank. But it was a standard thing to do after years of doing it and when you needed you equipment it was always ready to be used. Also every Sunday the old man cleaned all the air filters and greased everything and do any repairs that where necessary.

Probably get lost in the comments, But a "curtain wire", thin plastic coated spring, is great for clearing out thin pipes/lines.

Just a small suggestion regarding the 'Sight Tube'. As it is a very dark background, maybe you could paint the side of the fuel tank white or another light colored paint to give you an easier view of the level.

I didn't have near the trouble you did, but I was cussing at my wifes' Altima last night. Took the bumper cover off to replace a headlight, just to discover after putting it all back together, that I could have just reached my hand behind the tire splash guard. I'll never forget working for Rolls-Royce on turbofans. Engineers would have a bolt on a frame, behind a welded bulkhead. Can't remove the bolt without cutting and welding.

You have an inexhaustible amount of content and I thoroughly enjoy it. Keep up the good work.

I'm always amazed at your willingness to jump in and doing things that you have never done before and think your way through it. I wish I had 10 of you at work..LOL. Great Work.

What a shot of the sunset and sky halfway through your video. Truly stunning outlook.

I’m shopping for a mini excavator tomorrow and am incredibly grateful for the time and effort you put in to your excavator videos. Down to earth, understandable, and fascinating. I was entranced following your deductive reasoning and solving the many problems you found. Thanks a bunch!

What a frustrating project! Glad you pulled it off successfully John. Great video thumbs up.

Engineers can only design in so much autonomous maintenance (self-adjust brakes and valves). I don't know any way to have the machine change old coolant autonomously. This one's on previous owners due to use of too low a concentration of coolant and neglect.

I can't believe you take the time to film this,but im sure glad you do👍thank you Sir

Would love to see the pond that you had built. You did such a great job it would be nice to what it looks like now. Great video today once again John.

You should mount a led next to the fuel line with a momentary switch so when checking fuel just hit the button.

You can see the porch you renovated in the background there! Great vid sir.

I love that you took the time to change the fuel site hose and used the proper stuff. And you probably saved yourself some not too distant future grief by changing the coolant.

Thank you for your yanmar videos Noone has any help with these. You are a life saver.

Thank god I needed your video to end this awful week. Today I snapped a torsion bar on my 3 axle tanker truck, I was fully loaded with diesel :(

Great video John. I just started a channel with my 6 year old son, he wants to be a content creator too and watches every video you put out with me! He also like let’s dig 18 and Andrew Camarata. We have 85 subscribers but trying to get to 1000 is his goal and we will start making great content!

It was a pleasure to watch as usual. Thanks!

I came across your channel a few months back. I have to say I'm hooked now. I'm in the UK and have a 30 acre smallholding, so everything you do is somewhat relevant. Keep up the great video's! 👍

8 hours for a change of coolant? Well, there's a first time for everything 🙃 You got some beautiful weather. Love your videos - have a great weekend, and hello from Germany!

I always look forward to your uploads, very informative and well... entertaining. Thank you.

Lots of great improvements, the coolant issue was a must.

I have had lots of experiance working on numerous vehicles and plant in my time, I can honestly say never seen anything that complex, But as ever you sorted it out good for you John.

Really appreciate your content. Have a great Thanksgiving holiday.

Hi, Jon, you are blessed man, indeed. Wish you luck in everything about your machinery.

Never thought I’d see an excavator with a prostate problem 😂😂

Thanks for another great video John. They’ve been making radiator drain petcocks for a hundred years and they work just fine, sometimes a new thing just isn’t necessary.

John, Great video, Now thats farmcraft. Loved the drone shots at the end.

Low effort suggestion - a splash of white paint behind your “fuel gauge” tube would help visibility.

Couldnt believe yanmar built it that way, Thanks for your advise

A radiator flush was definitely needed. But since it's clean now and you know where the drain is. I would leave it. It will take 1 fifth the time to check coolant level every so often and draining it will be just the same. Yeah, how about a spray bomb of the unit with your logo on it. It's nice to see your videos when you post them. Very good tips and tricks. Keep up the good work.

Hi from Australia, great content, I learn something every video. I have a small farm with a few sheep and would love to see some content of how you manage your cattle. well done.

Good job John on the mini excavator

I have a Yanmar B7-3 and I got it overheating from the time I bought it. Thought it was air pockets in the engine because each time I would air bleed the radiator it stopped overheating for a couple weeks. One time running it hard pulling a huge stump it overheated and blew the cap off the overfill. Turns out I had a mouse nest between the radiator and oil cooler and oil cooler fins mostly plugged with oily dirt severely restricting air flow. Pulled the cooler, cleaned everything, installed a temp sensor and actual temp gauge (initially only had a temp warning light), added an auxiliary fan I can turn on & off if over 160, wrapped the coolant return hose in motorcycle exhaust fiberglass plus a reflective fiberglass piece between the hose and muffler literally 1.5” apart, and now it works great. Never use the auxiliary fan except long stump pulls in August but even then it’s not really needed. Don’t wanna rub it in but my drain is easy access through a plate underneath. Sorry yours was such a struggle, Jon. As always, great video & thank you for sharing. Stay blessed.

Outstanding video. Great persistence and commitment to doing the right thing. LOL Thought I was the only one who could get bad bounces like you did with the hose clamp.

Oh good... a Friday without a FC101 video is NOT the way to start the weekend... so, yeah. Thanks John. You are the cherry on my 5-day sundae. 😉

Preventive maintenance. Perfect John.

good job john as usual happy thanksgiving to you and your family,god bless.

I think that drain setup is the best solution given the space limitations. I bet if you maintain that coolant with your usual attention to detail, that drain hose and fixture will never clog again.

John…… as always just great DIY….absolutely one of my favorites

Thanks for sharing John, I appreciate it.

Great video & there's isn't enough room to work on any of it, even on a good day! Thanks, Jon! Lee

My vio55’s temp gauge runs just above the line you showed. It’s always had antifreeze in it, so it looks good inside the radiator,and it’s never run hot even after a day’s work. Thanks for leading with the repairs. I hope I never need to do as many as you, but you do them with skill and humor. I will be changing the fuel sight hose as well. It’s easy enough, so why not. Thanks.

As usual, amazing job you did. With all the maintenance update you did to your excavator and the light/medium use of it this machine can last 10,000hrs. Thank you for your very valuable/informative video 👌👌👌👌👌

John, you are absolutely right about the design ( or lack of) concerning the radiator system. Any cooling system on any piece of equipment is considered as Critical Service . The failure to provide a ready method to service the cooling system is an absolute invitation to NOT service the system. Your equipment repair videos are always entertaining, and more importantly, informative. I know quite a bit about heavy equipment, but I learn something every time I watch your work. Thanks, brother.

Hi John, I really love your videos 🤩. Love your sens of humor and honesty even when you mess up a little 😄. You have a wonderful property and some funny cows 😂. Keep on the good work 😁.

Mr John, before watching the video in full i said oh boy this is going to be good. Ive worked on yanmar engines and lets just say those engines are good until they aren't. Its crazy how they are engineered. And those engines have a bad track record for running hot. *EDIT* after watching the entire video, like all other videos this gentleman puts up; informative for the dyl crew. I love the setting, feels like myself at my house working on a piece of equipment. He's got basically the same tools I have access to minus the lathe and mill. Another great video Mr John. Keep em coming. Love this channel.

Another excellent video. Thanks for making these. FYI - Love the drone footages at the end. You have a beautiful piece of property.

Enjoy watching your videos👍

I hadnt heard about the dishwashing powder trick before, will have to keep that one in mind. It reminded me of a youtuber mechanic from years ago but I cant remember who, would sneak parts into the dishwasher to clean them. It did a very good job. Maybe the Mrs finally caught him in the act and he was never heard from again.

I run a 2007 Vio 55 over here in the UK and it's done just over 1k hours. And it runs below normal/middle on the gauge when working hard. It's good watching you sort out the problem's that I might encounter in the future. Oh, btw my one does track straight, well for now that is! Great video's, keep up the good work. 👍

Another Job well done John ,

When that first portion of coolant started draining out... 😱😱😱 It was so satisfying to see the rounds of flushes progressively get cleaner. Love how that piece of dozer tank got repurposed here. 😎👍

I don’t know about you Jon but I had to go to toilet 9 times throughout this video, but I’m running clear now ,thanks Cheers from Aus

More fun on the farm and another great project.

It was great to see learning about the pump

I have a 1937 Plymouth, the radiator water looked like yours and I had cooling problems. I dumped about 3 Ltrs of white vinegar in the radiator and drove it for about a week. Then pressure flushed the system. It was unbelievable what came out of the cooling system. I no longer had cooling problems but will repeat this next spring.

As always, great video!

Yes is a very lousy setup for draining radiator. I really enjoy your videos, they remind me of me when working on things. :)

Ear plug in the fire extinguisher nozzle, good call. Was pre-fire planning a building one time and one of the employees say me look in the nozzle and stick my finger in it. Asked why I was doing that. You’d be surprised the trash I have found in them. People walk by and to just be a piece of crap, stick paper or whatever in it. I’ve also found dirt dauber nests in ones that sit outside.

John, I don't think a lot of it either, but you have it cleaned now. And you know how to get to it, AND you aren't going to wait another 3300 hours to flush it. So I think your good.

Watching other people work is the best form of friday night winding down routine. I´d love to see that pump rebuild btw.

Good shout on that fire extinguisher. I had one save my ass a while back, when I found myself holding a 5L bottle of methanol that was on fire (long story), and I got away with just minor burns on my arms and some light equipment damage that I could repair myself. Without the extinguisher I'd have been seriously injured and the fire may well have spread to the house.

Good repair, you make it look easy.

John, I always love watching your videos!! You always do a great of filming and your comments are both informative and humorous!! When I drop a screw, it ALWAYS rolls way up under my workbench too!! 😩. Might I offer a suggestion…. With this drain hose on the radiator and not long ago the constant struggle of replacing the fuel filters….. I would add copper tubing and enough hoses to “get what I’m working on” WAY out in the ‘open!’ Make it easier on yourself for later!! Keep them coming!

Wow! All that draining coolant made me run for the bathroom! Love your videos.

Olways Nice to see you John what you do

Love the vid John! looks like your due for a new cutting edge on that push blade. Thatd make a good vid

Oh Jon what a way to hide a coolant drain. That little cone shaped washer that ran away reminds me of a similar one that happened to me when I was in High School. Seems that my "work bench " was an old kitchen table in my bedroom. Under it was an old B/W Tv chassis in a large box. I had an idea that I'd fix the tv but that never happened. I was working on a model on the table that had little tiny screws one of which I dropped while putting it in. The screw bounced off my knee and had just enough room to bounce further onto the box top which had the 4 top parts folded inward into the box and of course had enough time to sag down making a slide toward the middle of the box. Now again the teeny screw slid down among the tubes, transformers, etc. of the tv. Opening the box I couldn't find the screw. There were some unused holes in the chassis and wouldn't you know it the screw must have found one of the holes. Yup taking the chassis out of the box, turning the set upside down to unscrew the sheet metal bottom of course the screw had gone into one of the tv parts. After shaking the chassis for a while the screw decided to finally fall out. Putting the bottom back on, back into the box, taping the cover so I wouldn't have this adventure again it was about a half hour later I put the screw into its place. Sometimes we have fun in spite of gravity don't we.... JimM

That machine is amazingly compact. Maybe their focus on compactness instead of other attributes like easy maintenance? I liked the music at the end!

In my much much younger years ! I lived in Fargo, North Dakota . Alot of friends would have me change thermostats to 195 degrees in the winter , than back to what was recommended to a summer thermostat . Even back in the 70 's brand new thermostats were defective , ask me how I know ? I would do around thirty to forty changes a year . So every time I would use a candy thermometer a pot of heated water to test brand new and used to make sure that they were working properly . Back then changing was so simple , but putting new antifreeze in running to being to temperature ,then find out it over heated or not coming up to temperature was no fun either . So test them if possible. It saved me a lot of time .

The hose works fine. I have used the same for decades with no trouble. Does help to replace the hose every decade or so.

Hey, I'm the guy with your excavator again. Mine was also starting to overheat recently and I had no idea how to drain it either. I appreciate this video because now I'm going to have to go through the same exact process. What I may try to do is drill and thread a new drain port straight up under the radiator, and tie the drain hose to it so it's vertical, and if it clogs I can just fish a wire straight up into the radiator itself if need be. Wish me luck.
