John Deere 9870 STS combine has engine oil in the cooling system. Learn how to fix it RIGHT!

[@ZKMasterTech]

Just so you guys know- the oil cooler tested bad. Problem confirmed!

[@SteveNicoson-u1i]

Good going ZK. You knew. Nice.

[@popswrench2]

mostest common problem "irregardless" of color

[@rodhonco5681]

That would have been a hell of a lot of work to do all over again if the oil cooler was not the issue.

[@codyvandieren2069]

The Shania reference was one of the best I’ve heard in awhile

[@johnnyholland8765]

Yep wouldn't mind seeing that myself...

[@paulshamonis6362]

👍the Shania Twain reference!!

[@halwilliams1682]

Someday your kids will see this and appreciate how hard you worked to provide for them. Keep plugging away!

[@rdyardie]

It is a joy to watch a master mechanic at work. He knows what is required to fix anything green.

[@bruceguenther3256]

It amazing watching you work on all that Green Iron You sure know your Craft Can’t Wait to see your next project

[@ZKMasterTech]

Thank you very much!

[@Deerewrenching]

Hey ZK, I have had great success with cutting 25mm off those PIP bolts and installing them in tier 3 engines. Take your time cutting so the bolts don’t get hot and you’ll have no issues, done dozens of them and never had an issue…just a tip!

[@Failure_Is_An_Option]

Time stamp.... just way too much effort....

[@ZKMasterTech]

Cool, thanks

[@donalddehaven3229]

Love the channel. Nice to meet Ben.

[@larrycole4438]

As usual; another clear and detailed explanation of another job. You are the man ZK

[@johnbucklerfarms]

I remember Days like that on A Rooftop Replacing a AC Compressor on a 10 Ton Rooftop Unit!

[@richarddebertin6742]

Your skill and knowledge always impress me.

[@daveswensen9627]

Another awesome video Zeth! Both jumping rope quips were great.

[@jimclary7309]

Zeth, you're an awesome technician. I fill sorry for you two what weather conditions you put yourself through. Totally dedicated in what you do. Definitely look you up at the next one. Stay safe!!

[@MKHNitro]

Love the shades Zeth

[@genechronister7085]

Another awesome vid! What a job! Keep the deere's running! Stay safe

[@grizzlyridgerunner]

Late to the video today, another step by step repair video is a great video ZK MASTER TECH. Thanks for sharing 👍

[@ZKMasterTech]

Thanks 👍

[@dphillips705]

I can just imagine that conversation of the customer with his wife lol "i need dish detergent while your at the store" lol and separate recept for tax write off lol

[@johnwaby4321]

Nice work both of you 👍👍👍 Seem to be getting a few of those problems 😯

[@larrycole4438]

Looks like Ben has the makings of a ZK Jr.

[@llyodreeves4657]

Keep up with the good work love watching you on KZbin God bless love John Deere tractors

[@ZKMasterTech]

Thanks 👍

[@cuttingwoodagain]

Hi Zak. Your videos are awesome and thanks for sharing them 👍👍. Seems like a common theme in your videos and that is John Deere quality control!!?? Seems always a coolant related issue, fuel issue, transmission issues and may small things to cause the problem s but ending up costing $thousands of dollars to fix!! We left Deere last year after 40 years and now are totally Fendt. Will continue to watch a great mechanic on his daily mission 👍👍

[@T.Watts89]

His name is definitely not Zak......

[@arzamumma1202]

You are doing great, hot days can be a challenge 👍👍

[@slabslayer258]

Hott . It’s only 105° here today . Not bad at all and 80% plus humidity too.

[@SteveNicoson-u1i]

Thanks for another great video ZK and Joseph and Ben. It was most definitely interesting and very enjoyable to watch for sure. Well, this was quite the process. Before I get to going here , my compliments to you for knowing exactly what the problem was, saw your note that the oil cooler was bad, you hit it right on the nose. Good going. Also my compliments to you for continuing to teach Joseph and now the new technician Ben. Ben is a good one it appears, he got right after it and did the work to get it done. Nice job Ben. Am sure both of these gentlemen know the value in having you as the teacher. Well I really enjoyed this one. Just amazing what has to be dismantled to get to the source of the problem. Was great to see this and learn along the way. Thanks showing us the process coming apart and going back together again. You hit it on the nose, oil cooler bad. That oil really messed up a lot of parts and hoses. Good move to replace it all to prevent future issues. Love that battery powered fan. At least keeps air moving around you. Nice of the farmer to help with the flourishing of the system several times. About it I guess. Learned and saw a lot on this one. Thanks for everything ZK and Ben and Joseph. The Iowa farm boy. Steve 😊😊👍✅👋🇺🇸🇺🇸

[@danslawncare8594]

Doing good. Keep up the good work.

[@Ham68229]

Glad that Sloan lets you film all of this. It's all interesting to see how today's tech is going and how much it can be a pain to work on. Back in the day, the next gens could have been considered a pain but, easy now. LOL At least this was a fairly simple and easy job. Great video as always, cheers :)

[@BrianDuval-bv3ql]

It’s awesome to see people willing to edvance but money helps but pure that’s what I do regardless is always a plus it’s called pation alone gets the job done 👍

[@ronniedavis3273]

Another good one Zeth!

[@andrewkaras8001]

Great show love your work👍

[@PamelaBrowning-n9z]

Love this!!! Hi Zethro!!

[@johnbulla8708]

I'd got same problem with a nissan titan oil in the radiator. DONE had the oil cooler change, top of engine done, head is still great & been pressure test great no cracks no where. Put back together still got same problem.

[@williamorman4779]

Amazing job

[@rawhideadventures9515]

Good job sir.

[@welchfarmnc]

Like the battery tools . We only had air 20 years ago

[@awcvn]

Great Video!

[@MsWojtek18]

Another good video for dinner :D Greetings from poland :D

[@oldadthomas]

appreciate your work!

[@johnnyholland8765]

Oh the pitfalls of combine work. Belts,chains,gear boxes, internal stuff, electronic stuff, engine stuff and the list goes on. Plus they must be repaired usually while screaming hot and covered in dust and chaff. You the man Zeth. A more calmer (at least on camera) man and mechanic you will never meet. Try and keep cool. Heat stroke ain't fun believe me. It put me in the ER a few years back. Drink tons of water and take a break when you can...

[@ivoryjohnson4662]

Thank you for the video

[@Jimbo245]

Great video, a guy I work with at my dealership loves watching your videos, could you give him a shoutout in the next video, his name is Nathaniel W

[@JulianMoore-kx6op]

Great video content Zeth, hot stuff!!. Julian U.K KTGIM.

[@patloebertmann537]

You do great work

[@danielschmidt2721]

You can keep the combines I’ll keep working on my normal 9 series tractors lol 😂

[@larryburns4605]

I use simple green and then drain then flush with Cascade

[@BruceBergman]

Hot and dry or humid? Dry you can add misters to drop the effective temperature like a Swamp Cooler. Flush the tank with Dawn and a pressure washer. 3:26

[@isaacfichter2962]

@ZKMasterTech do you have a video where you remove and replace the electromagnetic clutch?

[@macdawg6403]

Nice Vid!

[@CRice-ln8lm]

Never thought I would hear the term Schmutz in a green machine engine bay.

[@matthewfelton8309]

Whats hilarious is every time im in that same hole i always end up singing that same song. 😂

[@HammerHead524]

@ZKMasterTech where did you get the hoses hooked to the transfer pump?

[@TroyE.Batterton]

Shania Twain jumping rope in the attic? How long have you been sitting on that one in the chamber??

[@oldadthomas]

GREATJOB!

[@SkylerNipp]

Have a question we have had a 2014 s680 for 4 years and just recently purchased a 2012 s680 one noticeable difference we have noticed is the 2012 you can not hardly stand to be in the shop even with doors open after it’s ran only a minute. The exhaust odor is terrible. Our 2014 we don’t have that problem. Why would that be??

[@jeffhatmaker817]

What year and how many hours on the combine?

[@formerfarmer1718]

Soooo. He wants to learn how to work on combines, huh? Here’s your sign!! Be prepared to spend lotsa time standing on your head. 😎

[@Thedevontree]

Did I miss the thermostats going in?

[@CarlosSilva-lq9nf]

Muy vueno los videos .👍🇺🇾🇺🇾

[@DougsHomestead]

That song at the three minute mark sounded like a woman was involved😂😂😂😂😂

[@evk10000]

@ZKMasterTech do you replace the seals in the thermostat cover?

[@xuser48]

He did so twice.

[@travismaier4567]

So damn humid the other day I breathed in and damn near drowned myself.

[@Rollin-With-Kirk]

Wondering how busy all of you JD tech's will be after JD moves to Mexico?

[@robertpowell7672]

Hi. Do you think it's a bit risky running the Combine before the leak test on the oil cooler came back. If the cooler had been OK and the head gasket was at fault, you would have re contaminated the system.

[@doughuffman5790]

Another engine flush would be small work compared to the head gasket.

[@Failure_Is_An_Option]

17:00 Your Pig Mat will filter the oil.

[@johnbulla8708]

Any thing else can I do.

[@ricko3145]

How good is it watching other people work😂

[@formerfarmer1718]

Knowing what I know today I’m sure I’d never put water/antifreeze in any of my machinery again. I’d use a product called Evan’s Coolant. It’s a coolant with a boiling point of 375 degrees (that’s right 375), non corrosive and doesn’t expand at heat causing overflow and no hotspots, It’s a new day……

[@johnlangley6449]

No leaks no dripping no problem 😅

[@johnbulla8708]

It's a cummins 5.9.liter desiel.

[@doughuffman5790]

“Replace most of the coolant hoses.” Because engine oil is deleterious to the hose ‘rubber’? How do you know which hose does not need to be replaced, all of them have been exposed?

[@john-i7e9j]

👍👍

[@johnbulla8708]

There no water in the oil pan or on the dip stick.No oil going back to the oil pan. Truck doesn't knock like it blowing up.

[@yohnny8839]

It’s hotter than 2 guys kissing out here. Been 100+ every day.

[@nicoquattro3950]

Thumbs up for singing Alice In Chains

[@lastguy8613]

Hope he dosnt get a copyright strike for that lol

[@farming4g]

Didn't know you were an Alice in Chains type of listener 🤘

[@Pete68T]

John Deer Should Be Making More Reliable Machines,Seems There Not Made Very Well,Always These Things are Breaking Down and Costing a Fortune to Repair,No Wonder they Dont Want Farmers Working on Them as They Would Never Get any Work Done🙂 They Need to Get Things More Reliable,Not More Complicated.

[@jeffb321]

The STS series are like 12 years old already...just normal stuff, nothing major.

[@lastguy8613]

They probably could make one that's fail proof but it would cost 10 million dollars and be too heavy to make it across a slightly damp field.

[@Failure_Is_An_Option]

Says the clown that has yet to master capitalization. But still squeezes out a emoji.

[@littlelifters7543]

Funny how you lost your place after your Shania Twain comment. You could see the image flashing across your eyes, no thought of tractors for a couple of secs.

[@bobearl7859]

Sounds like a design problem another reason not to buy a John Deere

[@Failure_Is_An_Option]

We all know you are not in this industry.

[@richardlong9877]

What brand were those angle wrenches you took cooler lines off with?

[@ZKMasterTech]

Tekton

[@richardlong9877]

My man spitting those sweet Alice In Chains lyrics!

[@ZKMasterTech]

My favorite!
