You did a nice job except for one thing. You did not flush the old coolant the proper way. When you fill the system with distilled water and then run the engine you have to wait untill the engine reaches higher temperature so as the thermostat opens. Only then you can drain the full system. Otherwise old coolant is trapped in the system and the thermostat blocks it from leaving the tubes. Keep uploading!
A nice video, showing where everything is located and how to get to it. However, he should have opened the bleed screw while he had the drain screw open. That may have allowed otherwise trapped coolant to come out. Think of how you drain the plumbing in your house. You open a valve at the lowest level but you also have to open a tap at the highest level. It's a matter of geometry and air pressure.
ID4nkOI I’m just getting ready to do mine, I too have the DT300i. How was the process? How do you get rid of air and n the system? Also which coolant did you use? Kymco recommends their own Kymco coolant but I’m in US and can’t get that. Thanks a lot! Hope you respond, I haven’t been able to find much info.
@@nemanjatosovic just remove the screw and fill the fluid from the radiator. Then stop it after the fluid comes out from where was the screw. Start the engine and don't put the radiator cap, you will see the remaining air slowly coming out. That's all!
Honda type II coolant for cars is the same and cheaper. It's good to see you maintain scooter but Kymco's maintenance schedule is overkill to the max. A spark plug will last longer than 6000 miles...coolant lasts longer than 6000 miles ...
I wish they would invent a better crankshaft rod bearing for these scooters because they don't seem to hold up very well even if you change your oil every 600mi, that crankshaft runs for about $400 plus engine gasket kit.
I wouldn't add distilled water on its own. You diluted the whole system with water doing that. When you add the new coolant, the water is not out of the system as demonstrated even by the fact that green coolant started coming out of the bleeder screw. Also the thermostat was closed that no real circulation is happening. Not the end of the world either way but what I do is I just drain the radiator and the expansion tank and that is sufficient. Then a year or two later I drain and refill the same way. Rarely do I open the block screw on my Honda Elite 110. Lasted 7 yrs and 30000 miles so far.

I have a Kymco 2003 Bet and Win 250 . Would it be similiar you think ?
Would it be a different process changing my anti freeze liquid on a sym jet 14 125
Thank you for the video, is the screw for the air in the same position for the downtown 300i?
I confirm it is

Same motor on both bikes
Can you explain to me how to change the engine spark plug? Thanks
Do you know if the procedure is the same for the Gti 125?

Where does your gauge read after this

Você não deixa o motor esquentar para abrir a válvula termostatica
Why was it green even at end?
piston replacement for kymco please video, im willing to pay
Pretty sure piston replacement is beyond basic maintenance. His bike only has a couple thousand miles. Hopefully the piston is still good. SMH.
your scooter need valve adjustment. its noisy when you rev up the engine.
well if everyone made videos so the workshops and garage would close
Too bad he never replied to anybody
somehow I dont feel comfortable following your video.
