Overheating Excavator: Cooling System Repair. Yanmar VIO-50.

This was not what I expected! So much harder and more time consuming than it had to be. What do you think? In the end I got it done though, and put the machine back to work grading and compacting the site where I removed that huge beech tree.

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!

[@Slider68]

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

[@grandy0406]

I agree about the drain, with your aptitude this should be an easy mod and interesting video. Always enjoy your work.

[@MrVajutza]

‘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 KZbin. 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.

[@06halfton4x4]

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.😂

[@bobkelly2447]

thanks for that ! I've never heard of that before . I shall keep it in mind for the future ! thanks !

[@MitzvosGolem1]

We use cascade in marine and truck diesel engine s to flush also Works excellent . Run for half hour get hot then flush out and reverse flush also . Distilled water only in any system.

[@Bob_Adkins]

Sodium carbonate / phosphate is fine for copper, steel, and neoprene, but it's corrosive to aluminum radiators.

[@MitzvosGolem1]

@@Bob_Adkins we only leave it in 30 minutes then flush several times.

[@DMSparky]

@@Bob_AdkinsI’d imagine decent coolant would have corrosion inhibitor additives.

[@KentDiego]

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.

[@tas32engineering]

Should have been a submarine fitter. Most delayed repair at full arm stretch can test even the best john.

take care - more antifreeze reduces the coolant efficacy , water is the better conductor :)

When the day comes for me to finally buy an excavator, I'm going to get this exact model since I basically have a video repair manual with every aspect of this machine now thanks to this channel haha. Im also dying for a video of repainting this unit.

[@claytonno2571]

just like the wife always says "function over looks"

[@regularman6328]

They don’t make parts for this model anymore. So that probably isn’t the best idea. You can get cylinder rebuild kits from the cylinder manufacturer, but other than that you are down to relying on aftermarket which is a shot in the dark.

[@AntonioClaudioMichael]

Right

[@isavedtheuniverse]

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.

[@lustfulvengance]

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]

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.

[@DieselRamcharger]

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.

[@JMassengill]

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.

[@Lsx70Velle]

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

[@ro0140]

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.

[@chrisluper6298]

Good to hear I'm not the only one who has used expressive language when dealing with problems created by others while trying to build or remodel a house or fix a truck. Architects and engineers think if they can draw it out, it can be built that way and it absolutely will work.. A belief I've had to disprove to them before.

[@meeklo86]

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! 🤣

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

[@Mad.Man.Marine]

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

[@jupesterr]

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.

[@jamiemajerick91]

I just love this channel. You always fix things the right way and take pride in it. Proper maintenance goes a long way. That drain line is cause and effect of an engineer sitting at a desk 😅

[@LisaMedeiros-tr2lz]

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.

To be fair, there was an accessible drain port. Sadly it wasn´t used for too long so it didn´t work anymore. The design by Yanmar was ok in my book. just neglected.

[@mst5632]

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.

[@nunyafugginbizness523]

I would have to agree with you, that routeing of the coolant hose is just a recipe for disaster. 1: having a hose that long that has no valve at the start will serve as a settling tank for ANY particles heavier than the water/coolant. It WILL clog. 2: that convoluted routeing system is so unnecessary, there is an easy access RIGHT by that hydraulic cylinder, just route it out to there. Better yet would be to put a 90 on the radiator and take it strait down and out. Why make things so much harder than they need to be? I swear, some engineers are sitting on their brains rather than using them.

[@stephenlindsey9233]

[@gsuberland]

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.

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

[@websitesthatneedanem]

Cool Stuff John! 👍👍👍

[@user-nq4ht7pb6w]

Thanks for another great post John. Not applicable to your Yanmar but I take the thermostat out when I flush the system in my ute. so I dont need to heat it up for each flush cycle and it minimises the risk of warping the warm head with cold water. I also use demineralised water.

[@twwtb]

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.

[@michelecrown2426]

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.
