I’m about to buy a 2022 Duke 390 with 2,500 miles on it… learning how to flush all fluids… your videos and commentary are best I’ve seen on YT. Thanks so much-you’re a treasure to this community!!
Thanks for sharing 👍. I spent £50 on Spal radiator fan ( direct fit once you swop out the connector hood) as the stock one prevents the air flowing though a large section of the radiator! Best upgrade to date for me given how noisy and how long the stock fan runs for even when moving in slow traffic - even if the weather is not that hot!
Mine is the 2017 .... which looks likes yours. KTM sold a batch of 50 in the U.K. for @£3000 at the end of 2017 so I bagged one - they had zero miles but had been pre registered. At that price it was too good to miss. 2 years later and I’m still loving it!
Just to say thank you done oil and filter change and coolant change by watching your videos saved me a fortune plus I know it's done properly used the ice coolant even though in the UK.
We run engine ice in Florida and it works great. btw - there is probably another bleeder bolt up high on the radiator that will allow draining and aid refill.
I don't know if its this way with the 390, but on some engines you have to continually have a stream coming out of the bleeder so it doesn't do a backpull of air when the coolant rests into the bottom of the engine. Probably fine not to on this bike but something to think about if your getting air pockets
Not sure this helps as much with a coolant change but have you tried the trick of using a flashlight from behind to be able to clearly see the coolant level on gauge window?
Yes I do that as well but while the fairing is off doing this procedure it was easier to mark it and use that reference until I was done. Thanks for the feedback!
WoW what a great video...for a homemade very well explained and very careful especially for newbies...thanks for your hard work Medicine...Great freaking job even for somerthing so simple...thumbs up and a like
I get that but it says there will be bubbles coming out and if you lean it right to make it the highest point you will never see that because the fluid won't reach. The method I used still worked just fine. Went out on a 100 mile ride yesterday and its performing just fine.
Completely understand your video. But if it takes 2 flushes to completely flush out your old green coolant with the white distilled water... It should it also take 2 flushes to completely flush out your white distilled water with the new blue engine ice right...? I feel you still have heaps of distilled water left in your system if you top it up now... Don't you think so?
Not enough to make a huge difference. If anything you would only be diluting the engine ice slightly. Freeze point on engine ice is -28F. I don't know anyone who would operate their street bike in weather that cold 🤣. The reason you want all the green gone is because you know it's all out at that point and the two coolants do not mix well together.
2-3 years or 24k miles is probably a more than safe bet. The coolant won’t likely go bad for quite some time beyond that but it will keep inner components happier
@@MotoMedicine904 I always thought coolant would last forever. At least on my previous twin cylinder bikes. I hadn't thought about the other lubricant qualities of the coolant. You think the Engine Ice works better than the Motorex 3.0 premixed coolant? Thanks. Kam
Yes there's a noticeable difference, its nothing out of this world but it will dissipate heat much faster. I wouldn't say it's slower to warm up by much, but at a traffic light it will stay cooler longer and thr fan won't run quite as long
@@MotoMedicine904 Good to know 👍, I just ordered a 2 bar radiator cap with a Guage built in for my KTM 450, It's probably past time to change my coolant anyways so I guess it will be the perfect time to test it. I am racing this thing in a GNCC style event so I want to be sure and take any WORTHY steps to keep it in the best mechanical shape possible.
If its the same coolant Type then you don't have to flush but it's a good idea to flush the system to make sure it's fully clean and will continue to be as efficient as possible
What is the main cooling effect of engine ice did you find? Is it the reduction of heat quickly or the coolant gets heated lately? Like I have been using Engine ice for the past one week. I couldn't tell the difference due to the weather maybe.
In my KTM 300 EXC in florida/summer without ICE it would blow off a lot of coolant every ride. with ICE I didnt loose much ever with normal riding. I run it on every water cooled bike/atv. well worth it. on ATV the fan was on constantly before ICE - on ICE the fans seldomly kick on.
You shouldn't do it with anything but distilled water. Regular water has a ton of minerals in it that will leave a scaling residue in your radiator and motor which can lead to a breakdown of the parts and ineffective cooling.
If you flush it twice just with distilled water doesn't it mean that when you finally fill it up with coolant, it'll still have too much water in the system? Same logic as flushing the old coolant, don't you need to flush all the water?
Not much is going to remain in the system, not enough to cause any harm. If you're using a 50/50 mix of coolant then you may end up at 60/40 at worst. Unless you plan to ride in below freezing weather there's no worry. A ratio that favors more water will typically cool better.
Its better at heat dissipation than standard coolants, so the bike tends to require less fan use and when the fan does run its usually for just short periods.
For the life of me I can't understand why this bike would come with "green" coolant from the factory when KTM recommends Motorex 3.0 pink fluid. I asked our local dealership how that affects the warranty if something goes wrong with the cooling system (ex: leaks, water pump, thermostat etc). They had no answers at all. Basically, good luck with that...
It must be a regional thing. Seems like all the bikes sold in the US have green coolant. I mean it does a fine job but engine ice is definitely a little better

Hey, I just wanted to say thank you. Started riding a year ago and you really helped me out with my coolant change.
Awesome! Keep the rubber side down!

Do you have a 1st or 2nd gen bike

@@gressshap8200 one day I may have to consider doing the fan mod. It gets hot here during the summer

I’ve always let it run with the radiator cap off and once it sucked into the system, you know how much more you need to add
Appreciate all the detailed maintenance/install videos! I’ll be using your powertronic install video this week 😀
Nice! I appreciate the feedback.
Thank you for taking the time to make this video. 👊🏾

“Lean right” means leaned to the right for the air to rise to the highest point which would, at that point, be the bleed bolt.

Very informative. Keep up the good work.
Great work! Did the bike runs more cooler? Thanks in advance.
Yes it runs a tad cooler and takes longer for Temps to rise while sitting in traffic.
I am confused between Engine Ice coolant and Liqui Moly coolant for my Dominar. Please advise.
Motocool OrganicFactory Line -35° / + 136°
How often do you recommend flushing old coolant and adding new coolant? Every 2 years?
2-3 years or 24k miles is probably a more than safe bet. The coolant won’t likely go bad for quite some time beyond that but it will keep inner components happier

Very Nice video, thanks a ton... be safe
Thanks dude u help me a lot...🤘
When u first put engine ice in your KTM DID IT QUICKLY RuN hot?
This happened to me too. Did you manage to find the issue?
Sounds like an air pocket. Squeeze the hoses with the cap off to help move out any trapped air.
How much coolant did you have to put in total including the coolant reservoir?
It was right about 1.7 liters. Engine Ice comes in 1/2 gallon bottles so one bottle is enough with a tad extra.
@@MotoMedicine904 thank you for the information.
Was there a noticeable difference in time to kick fan on or overall operating temperatures?
Yes there's a noticeable difference, its nothing out of this world but it will dissipate heat much faster. I wouldn't say it's slower to warm up by much, but at a traffic light it will stay cooler longer and thr fan won't run quite as long

Sweet. Ready to flush my gsxr
Thank you super helpful
Whats does the resevoir actually do?
Very informative!
Should i flush the coolant if my new coolant is the same color?
If its the same coolant Type then you don't have to flush but it's a good idea to flush the system to make sure it's fully clean and will continue to be as efficient as possible

I felt like my fan kicked on less often and when it did run it was for shorter periods of time

Can you do this with normal water??
You shouldn't do it with anything but distilled water. Regular water has a ton of minerals in it that will leave a scaling residue in your radiator and motor which can lead to a breakdown of the parts and ineffective cooling.
Great vid! 👍
Very helpful, thank you
You're welcome!

Good stuff!
So it’s ok to start the bike for a little bit with no coolant?
There should always be fluid in the system when it's started wether thats coolant or water being used to flush it. Never dry though
Does this apply for the 1190 RC8
Obviously drain and fill locations will be different but the steps are universal themselves.
You can either use expensive Wuerth Radiator flush or cheap coco cola/pepsi and then use distill water or vinegar
What’s the green coolant isn’t motul pink for this bike
I believe the pink motul was not used in bikes for the US.
What adavantege ice coolent oil for duke 390
Its better at heat dissipation than standard coolants, so the bike tends to require less fan use and when the fan does run its usually for just short periods.
@@MotoMedicine904 ice coolent how much cost and how many litre?
Can i use tap water
Not a good idea. Tap water has tons of minerals in it that can leave deposits in your coolant system.
Ok,ty
How about boiled tap water
Still no.
For the life of me I can't understand why this bike would come with "green" coolant from the factory when KTM recommends Motorex 3.0 pink fluid.

@@MotoMedicine904 - Definitely. We already flushed it at 2000 miles and replaced with Ice.
Ah shit. I very much did not follow this guide when changing my coolant 💀
VERY OVERPRICED COOLANT
