- While waiting on a few more engine bits for the Rc390 (valve shims atm) I figured I could tackle some of the other projects on the bike. Got the radiator upgraded and looking spiffy today.

You don't have to solder anything. You can take the flat copper pins off the SPAL black connector and just put them into the KTM white one...
Yeah I was looking at the pins and the way they lock into each connector is slightly different and I didn’t want a chance of losing the fan so I went with swapping the whole connector.
Bro, thanks a lot. My bike just overheat and the head gasket might be blown.
After the fix, surely I will upgrade the fan and also radiator cap. Thanks a lot!!
Good luck with the repair!
What a great video ! Did that actually helped to keep the ktm cooler. Also would you mind telling me how does it perform in the track after that modification, does it actually run cooler and less prompt to engine blowing up ? Thank you in advance
Thank you! It keeps the bike much cooler, the temperature bars are now consistently 2 bars below the upper "hot" marking. I haven't taken the bike to the track yet as I'm waiting to pull the trigger on some suspension but I'll definitely report back.
VA32-A101-62A SPAL for duke 390 2017 is a direct replacement of the original one?
It would have been better if you havent cut the wires of the spal fan. You can just easily remove the white plug of the old fan and transfer it to the new one so that it the wires remain original. Nice video btw 👌
Thanks! Yeah I pulled the pins and the way they locked into the connectors was different between them and I chose to take the route that would hopefully keep them from pulling out over time. It’s totally possible to just repin them for sure!
Hey, thats not the fan that comes in the image. Oh, i found it right, beside.
Gracias parcero!
Could this fan cause any issue with the electric system? I mean, being more powerful... That's my only doubt about doing the upgrade... What do you think about?
I doubt it, I didn't look into the specs on amp draw but it's a pretty common mod and I haven't seen any complaints regarding it.
@@GarageAddiction Thank you!
@GarageAddiction I am planning to install 2 Spal fan on my KTM RC 390. I noticed in some other videos that you can just move the fan pin to the KTM connecter. So here is my question: Can i connect 4 pins in the same connecter (positive postive pair) and ( negative negative pair), will that work? Or do i need to cut the wires and solider them? Here is the other video look at 12:04 mins
Nice one brother!
Thanks!
Install fan in opposite directions and fan air flow radiator side.👍
Really nice informative video👌
Can I upgrade this Spal fan to My KTM Duke 200 and wanna know exact Clutch measurement and free play in this KTM bikes for optimal performance n mileage...Thanks😊
I don't know how similar the two bikes are, I imagine they share a lot of parts so the fan would probably work. For the clutch are you referring to the lever play?
@@GarageAddiction Yess, Clutch lever play and as well in Engine side clutch play
@@cah7925 as long as it's fully releasing and engaging that's the best it can be. Big adjustments happen at the engine arm and small ones on the lever. Personally I like my clutch to engage almost as soon as I start letting it out. I know others that prefer it closer to the end of the lever sweep but that's just preference.
Cool vid man, thanks for sharing your upgrades with us! By any chance do you have a link (or SKU) to that radiator cap? The link in your vid description is the same as the rotary tool on Amazon. Thank you!
Ah sorry about that, I updated the link! The part number is also 212-1601. Thank you!
@@GarageAddiction Sweet, thank you!
I wonder how this fan performed.
I can see it won't work as well as the OEM because it doesn't have any cowling.
It's significantly better than OEM even without the cowling. It'll drop the temp bars super quick.
@@GarageAddiction
Thanks. This Rad fan is getting popular in my country for KTM 390 too but it's a bit expensive.
Hi bro. I purchased a Helix Rad cap 1.6 bar, and my coolant from the radiator leaks. I think the spring are soft compared to the stock. Is your spring soft too? Or is this a faulty item I purchased?
Sounds like a faulty cap, mine requires about as much effort as the stock to compress and get in place and it doesn't leak from the cap at all.
post a video after fitting it.. sound / vibration if any ?! how much it is better than stock
I kind of touched on it in a vlog but It's roughly the same volume as the stock fan, no noticeable vibrations, it's on for much less time and usually only at stop lights or in traffic. With the radiator cap and the fan the bike is regularly 2 bars below the hot line.
@@GarageAddiction thanks a lot for the reply . what changes the cap can do. .sorry no idea about it. so asking
@@vickyjoe3657 It allows for higher pressure which raises the boiling point of the coolant so you're less likely to boil over.
Can i replace the radiator cap while the coolant is full? I scared it might spill out the coolant from the coolant reservoir as the coolant reservoir is placed higher than the radiator
If you clamp the line leading to the rad you can swap the caps with the bike on its side stand, you might loose a tiny bit when you open it but not much at all.
Have you ever tested whether it's really worth it to purchase a Dooxi Car Adaptation products?
I've never tried any Dooxi products
FRIEND, IT'S ALREADY A FEW MONTHS SINCE YOU MADE THAT MODIFICATION. HOW WAS IT ... YOU REALLY CHECKED THAT IT COOLERS MORE COMPARING TO THE ORIGINAL?
It cools down significantly faster and the fan comes on less often. I'm thrilled with it.
@@GarageAddiction I saw a comment about rain, notice any issues with that?
What coolant do you use? Is is still the same coolant you used with the stock fan?
I use distilled water and water wetter. The coolant is the same type before and after the fan and cap upgrade.
Do you know how many seconds does it take to cool down the radiator? Thank you!
It usually comes on for about a minute or two depending on the air temp. I'd say it's at least half the time that the stock fan is on.
can you give the specification of radiator fan of ktm rc390
Not sure what the oem fan cfm is but the spal has kept the bike consistently cooler
What exhaust did you used?sounds good on the video
Thanks, it’s a Yoshimura.
@@GarageAddiction slip on yoshimura only will make a difference in sounds?
@@betlogenako7193 the slip on will change it slightly and the full system will make it throaty
@@GarageAddiction do you have the link for full system sir?any suggestion where to buy it online?

Sir, I m facing a lot of radiator coolant overflow issues while on highway runs . Will helix 1.6 bar solve that issue?
The radiator cap helps raise the boiling point of your coolant and may solve your issue. With my experience on this bike you will probably still get overflow issues unless you improve the fan or radiator for overall cooling.
@@GarageAddiction Thank you so much I have KTM 390 duke and stock fan sucks bought the Spal fan and will change the thermostat easy also as I m not riding the bike after long periods. Hope all that solves the issue.
Really thank you for your reply.
My bike runs way cooler with the fan and cap. I am thinking about a radiator upgrade since it still gets warm on really hot days or 2 hour + rides.
the stock fan should have covered the whole 80% of radiator i don't get it how come it gonna keep radiator cool with little much of diameter
I feel like the rad is a little undersized for the bike. It’s fairly thin and doesn’t have a huge capacity. The fan moves a lot of air which helps but it would be nice to see more coverage for sure.
@@GarageAddiction some bikes have curved rad
is this compatable to duke 200
No idea, I would guess they're similar enough that it would be though.
Was the new fan more powerful? Spec? I'm assuming better than stock?
According to many owners it’s more reliable, quieter, and overall more efficient at removing heat probably through higher cfm.
Love your channel and well made videos. Courios to know if you learnt mechanics?
UA-cam is terrible for parsing comments, sorry I missed this. I learned from experience, every mistake or win is a lesson learned :D
anybody knowqs..... Is that a 5.2 inch fan for the 2015 ktm rc390 or do i need to get a 4 inchj... ?>>????j HELP PLEASE
5.2 is what you want. amzn.to/3bzPNt9
Would this be the same process on a 390 Duke?
Not entirely sure but I believe is should be the same. The two bikes are nearly identical.
What if we put in a slightly bigger radiator?
Honestly that's on my list too, I feel like the stock rad is undersized for this bike.
@@GarageAddiction I think the bigger radiator its more promising since it can handle more coolant. But I can't find any aftermarket one that males for ktm models. Any idea what radiator maybe can be used?
@@soemardi8885 There isn't a whole lot of space for a bigger one but there are some aluminum ones on ebay that are slightly thicker and may hold a touch more. When it's functioning properly it doesn't get too hot using the stock setup but I haven't had it to the track.
@@GarageAddiction yeah i found that too, but i think it mau hard to find now.
I'm just curious about using another aftermarket motorcycle rad, but it have a little bit taller dimension. Do you think it will work with stock waterpump?? Still have figure it out the mounting and routing the hose. But i think mybe it will work if waterpump can handle it.
@@soemardi8885 the stock pump can probably handle a slightly larger rad. It's not the most robust and the impeller is fairly small though.
What is the price for the radiator fan
They’re about $60 depending on where you get it from. I threw a link in the description for amazon.
The price is high actually, I bought one from KTM showroom and they cost me 52$
Can i get it on Amazon
Yep, there are links in the video description to all the parts!
The cover-less fan you are installing is highly susceptible to 🌧 because it causes electric ⚡️ to error
The shroud is for directing air, both fans are equally sealed units. There shouldn’t be any additional risk from the elements.
@@GarageAddiction
Yes you are right the shroud is for direct the hot air downward.
I have both of the fans and for quicker cool down the cover-less one is quicker than the shrouded one.
But I once rode in a heavy rain and there’s plenty of water 💦 scattered throughout the radiator and after a couple of minutes later the fan dead and here comes the “high coolant temperature”
Thats a bummer, since it barely rains in California I probably won’t be riding in it anytime soon but it’s good to know.
@@GarageAddiction I suggest that you have to avoid riding through flood or heavy rain 🌧
Hi, what fan do you use now
Is it sealed like the stock one?
I'm collecting money to buy deam.bike
Bro your aftermarket fan looks nothing like the one depicted on the package. You're probably scammed my dude
Pretty sure they use a somewhat generic picture for their fans based on size. Their website image of the fan is spot on for what I got.
Because my SPAL 5.2" 30103011 just arrived today. And tbh it looks completely different from yours (it's got about 7-8 blades, different motor design at the back)
That’s odd, the 30103011 on the spal site is 5 blades. Where did you pick yours up from?
Garage Addiction dun worried,u got correct part like i do..n another thing is the connector is reusable..no need to cut actually..just disconnect the pin from main connector body..
is this rc390 the post 2017 model? i thought these 2nd generation rc390 has the heating issue fixed?
This is from a 2017, any time spent sitting in traffic or low speed cruising got the temp up very quickly. Even after the upgrades on some of the really hot days here in California (100+ degrees) , the fan will run constantly trying to cool the bike.
