How to: Kawasaki Z800 coolant flush

DIY steps on how to flush and fill up fresh coolant for the Z800.

[@mushroomcloud1]

That is a huge pain in the ass for what should be a simple task. Shame on Kawasaki for making it harder than it needs to be.

I'm in love with ur channel since the first day I watch and btw your friend cute 😝😍

[@thesighbored]

Thanks for viewing.. I'll let my friend know about it. :)

[@adiknaim]

ur neighbours will probably think u guys just killed Predator

[@thesighbored]

LoL, yes or a wounded Hulk passed by the area.

Cool tutorial Bro. I had to do coolant change for my z8. Just got hit by a car on December 21. Luckily have slider & engine guard. I notice my coolant are really on low level as more than 3 years didn’t change it. 🇲🇾👍

[@thesighbored]

Need to change coolant a bit more frequently 😁 glad to hear not badly hurt or damaged

[@azizkaria414]

There are two screw for us to blow the coolent. Bottom near the gear paddle and a screw on block (somewhere near header)

[@thesighbored]

I only know of the one near the shifter which we open to let the coolant out.

[@minc3]

nice one!!! followed your channel for quite some time. interested with the z800. however i heard that there's some issue with the valve. is it true there's issue with the quality or its jz the style of riding?

[@thesighbored]

There are some cases, but it's not some frequently happening to the majority of the owners. Z800 is probably one of the most common bikes on the roads now, maybe even surpassing the ER6 model. I have quite a few friends that have been riding their Z800 for quite some time now, not hearing any troubles from them. Thanks for viewing!

[@minc3]

+TheSighBored thanks for the reply!!!

[@TheAverageGP]

awesome tutorial thanks.

[@thesighbored]

Thanks for viewing!

[@swws4248]

Hi, great content ! What’s the normal temperature range of the bike ? Ive seen it went above 103 deg celsius but im unsure if that seemed normal. Got the coolant replaced about 3 months ago ! Thanks !

[@thesighbored]

This bike runs a bit hotter than others, normal running on other bikes usually 89-90c but this one was 98c I think.. Not sure why.. Thanks for viewing!

[@thekidless7682]

Hi,love your content! Not many around with our local Malaysian accents,haha.. I think it has to do with the radiator fluid-to-water ratio. I monitor my car's ratio as well with a special ratio-meter whereby it tells you how much a certain fluid mix has deteriorated over time. Quite a cheap and ingenius little tool. Typical life span of fluid these days are 3-5 years. There are long life varieties as well and usually dictates the selling price. Just make sure it's the right type for the Z. It's a simple apparatus actually, where you just need to suck out a sample of fluid from your radiator and the float in the apparatus simply just points to 1 of 4 markers telling you if the radiator needs topping up of radiator(pure or 50/50) fluid in order to maintain the level and ratio of cooling and rustproof efficiency. Too high a ratio of water to fluid will cause a higher temperature reading. Hence it is important to keep a 50/50 ratio for optimum cooling and rust protection. Too low a ratio over time would effect the corrosion protection level the fluid is supposed to provide over time and it would cause the radiator channels to rust. You will know this once you've purged the old radiator fluid out of the bike. So,i always keep a 50/50 mix of fluid around for topping up the radiator's expansion tank. Never just add water as it will dilute the ratio over time and render your coolant pretty much useless. It happens to the best of us. And by the way, always use distilled water as pipe water will cause heavy pitting in the radiator channels over time as it contains minerals and rust particals. You can simply get distilled water from the 7-Eleven to mix if you are using the pure type. I do it by mixing 1:1 in a measuring jug.Hope that helps..😊

[@thesighbored]

Thanks for sharing! If not mistaken most of the coolants now come premixed, I rarely add water to radiator anymore.. I'll usually just top-up with the same brand coolant if needed..

[@xGotstarionHD]

very helpful, thank you.

[@thesighbored]

Glad it helps, thanks for viewing!

[@monejati1847]

I got a 2013 z800. And just checked my water coolant was on L mark. But nothing wrong with the radiator and it’s doesn’t get that hot which let u think something wrong with engine. Everything totally normal even in summer. Do u think I have to change my water coolant or just fill up till F mark?

[@thesighbored]

It's better to have the coolant reservoir at F level since it's designed to hold that much coolant even if just as standby/extra.

[@monejati1847]

Thanks for replying

[@zergothikaify]

Is the bike heavy Bro? A local dealer recommended this bike and been contemplating between MT 09. Your opinions appreciated.

[@thesighbored]

Yes it's heavy for it's category, you should wait for the 2017 MT-09 and check that one out.

[@zergothikaify]

Yepx, it's out where I'm at. Was interested in the Z800 before mt 09 2017 was out. Thus, wanna check how's the long term review.

[@thesighbored]

Z800 is a good motorcycle, I have many friends using it, the only concern is the weight but once you get familiar with it and handling the bike, you won't even notice the weight. But of course the MT-09 has more lower end torque plus it's lighter so much more nimble, hopefully they fixed the soft front fork issue, the previous one was way too soft.

[@Murphy_x]

good video man it seems so complicated procedur to do such a simple task wanna ask you what it the normal temp when you start the Z800 ?

[@thesighbored]

It's complicated due to the position of the radiator cap.. Normal operating temp is roughly 89 to 90 more or less a bit, if not mistaken.

[@Murphy_x]

@@thesighbored thanks for quick reply, i have z800 when i start it the temp is 40 and start increasing quickly even i dont ride it, is this normal or not ?

[@thesighbored]

@@Murphy_x Yes, that's cold start, the temp will go up to the normal operating temp like I mention, and will even get hot where the fan will kick in to cool down.. That's normal..

[@BMWF900R]

Wow that is rocket since just to get a bit of water lol I don't know I'm upbtibthe task. Main is getting hot around 95 degrees in winter outside is like degrees I think in sammer will be very hot is that normal

[@thesighbored]

The cooling system should keep the engine from passing the overheating mark, if it's not then there should be something wrong.

[@muhamadnabilbinmatdaud4925]

How much liter do we need to change z800 coolant?

[@thesighbored]

Unfortunately we didn't measure exactly but usually it's around 2L, I think if you Google it or check the service manual it will provide the amount.

[@wonderwheels5332]

Bro I hve z900 nd I m facing coolant boiling issue in my bike when I ride for 6-7km then bike coolant leaking from the overheating pipe nd also boiling problem in the coolant tank,can you please help me

[@thesighbored]

Is the water pump working properly? Does the coolant look like milk tea/muddy instead of it's normal color? Is the radiator stuck? Have you replaced the radiator cap before/check the cap pressure valve/spring is OK? There's a lot of possibilities you need to check one by one or have a mechanic diagnose the issue..

[@wonderwheels5332]

@@thesighbored I visited kawasaki they can't diagnose the issue, can you plz provide your contact number I will call you

[@jegasellan1667]

Is that before remove the tank tube must clear all the fuel from petrol tank? Sry if I'm asking stupid question🙏🏻😊 i don't know what for is the tubes actually

[@thesighbored]

What tube are you referring to? You can have fuel in the tank but try to not have so much fuel then it wil be heavy when you remove the tank, and the fuel won't spill if you disconnect the fuel line there's a valve to stop the fuel so it doesn't flow when you remove the tank.

[@filaz]

I think he means the 2 black tube connected side of tank. Bro that is drainage tube for over flow fuel and drain the water (from rain or wash) in case there have water trapped inside between fuel cap. Sorry if i mistaken.

[@thesighbored]

The black over flow tubes? Yeah those tiny ones are the over flow tubes also rain water draining if park under the rain and water manages to get past the fuel cap.

[@MrStefler7]

hello, what model of rearview mirror is that?

[@thesighbored]

It's a Rizoma type imitation. You can search for it on Aliexpress.com

[@QAnyui]

came by car? btw, is z800 share the same frame/chasis with the 2013 zx6r?

[@thesighbored]

Yeah, had to bring along paddock stand for the Z800. Nope totally different frames.

[@QAnyui]

+TheSighBored how long does it take, starting from removing untill reassemble the bike panel and seat?

[@thesighbored]

It took us a bit of time because we both needed to figure out how. All in roughly 30 minutes, lesser if you already know what to do.

[@abejo7888]

Coolant jenama apa tu bos?

[@teddybeer1757]

Wont the engine get damaged by running it without coolant? I saw that the radiator was smoking when you were pouring water to flush the cooling system. Won't the water pump wear off due to running dry?

[@thesighbored]

For just a short moment it's OK, plus the engine wasn't running at high temperature, the reason for letting it run was to flush out any remaining coolant still the system.

[@teddybeer1757]

@@thesighbored Alright, but why was the radiator overflowing, when you were filling coolant in the overflow tank?

[@teddybeer1757]

@@thesighbored by the way.... how is the Z800 as a second bike? Is it hard to handle this bike? Can I manage it? I am riding a 125cc for 5 years now, it this bike too much for my skill level? Please help me I like this bike.

[@thesighbored]

We put water to flush the coolant out while the engine runs so the water pump runs and flush the coolant + water out, the rate of water entering was faster than the draining at the bottom so the overflow happens not a problem..

[@remuslupin8313]

shud avoid using ball point end to open the screw. might damage the screw or the ball point crack.

[@thesighbored]

Which are you referring to?

[@shahrulekran2615]

on what basis should we replace the coolant?

[@thesighbored]

If the coolant is old then it's time to change. Roughly 30k km can consider to flush and put fresh coolant in.

[@zerouzer]

do you recommend to diy this job? getting a used z800 soon and need to change the coolant since the bike is almost 4 years old with not much use

[@thesighbored]

If you are trying to save some money, yes, do it yourself, otherwise just pay a good mechanic to do it for you. Pain in the rear cause need to remove the cowling and tank. 4 years without coolant change? That's not the only thing you need to consider changing. Fork oil, brake fluid, tires, chain, etc. Check them all.

[@zerouzer]

TheSighBored thats true. changing everything u said :)

[@thesighbored]

Uh, check before change. Get it to 66SpeedBike and tell the boss Saibot sent you over for full check-up.

[@zerouzer]

TheSighBored was just browsing their fb page lol. thanks for the recommendation!

[@69HotRabbit69]

or you can just empty the coolant reservoir run the engine , empty the reservoir againe and then proceed to fill in the reservoir to avoid all the trim removal and tank elevation

[@thesighbored]

Emptying the coolant reservoir bottle is not a full coolant flush..

[@thundersteel84]

aaak aakk aaakkk..nice background music...hahaha

[@HornyFX]

What exhaust is that on the z800?

[@thesighbored]

It's a Giannelli, I don't know the model.

[@tamcruztamcruz7456]

Sorry I don't have that bike to do replacement, if I can get my hands on one to do I'll share.

[@jalaluddinabdulhilmi]

Kalau tak tukar coolent ada kesan tak pada motor

[@johnwright6995]

holy crap have to take half your bike apart to change coolant got a 05 z750 it's just 1 side panel

[@thesighbored]

Yeah that was what I was amazed with as well, not sure what the designers were thinking when they designed the cooling system. All sorted out on the Z900 though.

[@shaffiq]

Hey +TheSighBored, perhaps you can do the DIY coolant flush on your ZX6R as well. Glad to see ^_^ So I roughly get an idea to do it to my R6 as well :D

[@thesighbored]

I don't think they are the same in terms of what plastics need to be removed, I probably won't DIY it but will be done at the shop, mainly because I need to completely clean out the old coolant as I plan to run Engine Ice for the bike.

[@shaffiq]

Alright~ ^_^ I am planning to DIY yhe coolant but hmmm... it's better to do it at the authorised shop else 'kaboom' problem sana sini :v

[@thesighbored]

Try searching for R6 DIY videos and see if you want to take up the challenge.. :)

[@shaffiq]

Alright

[@ffh2303]

What brand of coolant is that? And usually at what interval do people change their coolant?

[@thesighbored]

He bought Abro coolant from DIY shop. Usually 30k / 35k can consider to change.

[@joehooyen725]

Good job & save some cash...excellent !

[@thesighbored]

Yeah it was a good experience. :)

[@shahrul1616]

How much mileage need to change the coolant roughly

[@thesighbored]

If not mistaken, every 10k km.. Or every 2 times you do EO change, you change the coolant

[@shahrul1616]

How much cost if I'm send to foreman..it seems so complicated to dismantle all that cover

[@thesighbored]

@shahrul1616 I'm not sure about workshop charge, need to quote from workshop.. Different garage may charge differently..

[@MohsinChan22]

banyaknya la part nak kena buka just nak capai coolant cap tu.

[@thesighbored]

Yes, I was amazed as well how much we had to do just to reach the cap.

[@MohsinChan22]

well bro, for naked bike they need to hide everything neatly.

[@hairulhairi5522]

wow....interesting video u uploaded just now...now i know z800 can squirt also....hehehe

[@thesighbored]

Oh yes they do! LoL!

[@hairulhairi5522]

[@MrEv893]

wooo...what a pro!!...:D..can I send my bike for coolant flush??..

[@thesighbored]

You may send it to him, not me. LoL. Already showed the steps, can try it out.

[@MrEv893]

+TheSighBored hahah...just joking only..my bike still new 2 months..anyway good step..:)

[@iismemeisi6800]

berapa liter coolant yg diperlukan tuan

[@thesighbored]

Kita tak ukur tapi untuk moto besar selalunya 2L coolant (2 botol) cukup, ada balance sikit lagi boleh simpan untuk top-up.

[@RedMechaMaru]

how to check the coolent level? and when will you "service" ?

[@thesighbored]

Usually just checking the coolant reservoir (white/transparent plastic bottle) for the low and full level is good enough for knowing the levels. If low, can top-up through the reservoir. To change coolant, it depends, roughly 35k km plus or minus should be good for replacement.

[@RedMechaMaru]

+TheSighBored terima kasih for the info and video. 👍

[@haceneboubekeur4299]

I don't bring my z900 to them for changing liquid lol

[@thesighbored]

If you want to do it yourself, you can.. Or if you decide to have a workshop do it, you can too..

[@pablogusta8954]

Bro... Berapa liter satu botol ni??

[@thesighbored]

Can't recall the price, but you check at Ace Hardware store.

[@pablogusta8954]

Thanks bro... First time you balas ni... Rasa wow

[@thesighbored]

LOL.. Just a normal reply.. :)

[@roderickcavallo8244]

Is that organic or regular coolant?

[@thesighbored]

I think it's regular coolant.

[@roderickcavallo8244]

TheSighBored I guess you used regular as well

[@thesighbored]

Yup, I think so too, the pre-mixed type so no need to add water.

[@roderickcavallo8244]

TheSighBored the thing is that kawasaki recommends replacing coolant every three years. Only organic coolant needs to be replaced more than 2 years

[@thesighbored]

Every 3 years? Wow, I didn't know that! That feels quite long. Coolant isn't that expensive, I would still change it out at least 1-1.5 years or depending on the mileage.

[@cjgan80]

[@mohdanis9381]

flushing er6n is way more simpler than z800. did mine under 30 minutes.

[@thesighbored]

Yeah.. It took more time because the tank needed to be lifted.

[@danialariff7731]

How do I get those coverset? Freaking sick

[@thesighbored]

What cover set are you referring to? Those are just normal Z800 covers..

[@danialariff7731]

Oh I see. I'm quite new. Just bought a z8. The cover set are not the same as yours. Haha

[@thesighbored]

Probably just the color different..

[@danialariff7731]

Haha I like yours better. Anyway. Happy riding bro!

[@thesighbored]

Ride safe & safe ride!

[@wk3837]

how many liters need？

[@thesighbored]

We didn't measure exactly but having 3 liters should be enough with a bit leftover.

[@RIDEINSECRECYDMV]

So complicated lol, z1000 seems easier to work on :(

[@thesighbored]

Yeah, mainly because of the radiator head/cap itself is under the tank. Otherwise would be much simpler.

[@mohdyaseer8037]

How about Z900?

[@elikhwanoura]

the crow jealous because z800 is also black like her.. hahaha :D

[@thesighbored]

Maybe they thought it's a new crow joining their crew.

[@elikhwanoura]

+TheSighBored haha.. Btw i still waiting my bike. How long u wait to apply loan?

[@thesighbored]

Should be quite fast, usually within a week. If you have strong supporting documents. Need to press your salesperson to follow up, or you follow up directly with the bank.
