changing the antifreeze on my roketa mc-54-250b

[rosado1234]

i am very new to this, i am scare to change my antifreeze on my roketa mc-54-250b, because i read that t the radiator needs to be burp, i don't know how to do that, can someone tell me how to do that, and the worst part, i don't have hook up for water hose, so i have to use bucket

The way I did mine was to take the lower radiator hose off (on the throttle side of the bike). Take the radiator cap off from under the seat bucket. I than ran some water thru mine to flush good. Put the radiator hose back on and fill with your fluid of choice. Replace cap and let run til good and warm. Take the cap off (when cool) and fill to the top again. Repeat the same procedure until the level does not drop anymore. May take 4,5,6 time to get it full. Check the radiator tank. And then..."SCOOT ON!!" Hope this helps.

Empty out the old coolant. I use distilled water then to wash out the system. Replace the drain and refill with coolant. Squeeze the radiator hoses as it is warming up to push out the air. You can also remove the air from the system at the thermostat. There should be a small tube that u can pull off and replace after a second or two to remove the air in the system. Do it just after u crank the scoot so the coolant will not be hot. Once the thermostat opens the coolant will drop. Refill and squeeze rubber radiator hoses again. Once the coolant level is stable, say 5 or 10 minutes, u are done. Take it for a ride. check for leaks. if it is getting hot , u still have air in system so burp the system again. Do not try to burp at the thermostat with the engine hot. It will burn the hell out of you. Wait for the scoot to cool.

since you didn't state what size your engine is i'll post the procedure for the 244.
putting the engine size in your signature will aid greatly in the future should you require further assistance.

1. purchase a 50/50 premixed no silicate, no phosphate antifreeze.
2. find a suitable container to place under the water pump. this container must hold approximately 2 quarts.
3. remove radiator cap.
4. place container under water pump and remove hose.
5. after fluid drains replace hose. you can blow into the hose to remove more fluid.
CAUTION: antifreeze is poisonous to you and animals, DO NOT, i repeat, DO NOT swallow any of the antifreeze nor leave the container where pets or other animals can drink from it because they will thereby killing them.
6. fill radiator with fluid until full.
7. replace radiator cap.
8. place scoot on centerstand and start scoot.
9. let run for 1 to 2 minutes revving occasionaly.
10. let engine cool for 15 minutes.
11. remove radiator cap and fill radiator with fluid.
12. replace cap and go for a short jaunt around the block.
13. let engine cool, remove cap and check fluid.
14. refill as necessary.
15. park scoot and check for spots the next day.
16. correct any leaks you find.

that's all there is to it.
remember:
antifreeze is poisonous, do not leave uncovered containers where animals can drink from them, because they will.
antifreeze expands when warm/ hot so don't completely fill the radiator. i leave mine about an inch below the fill neck.
use only antifreeze safe for aluminum engines (no silicates, no phosphates)
