Coolant Issue

[agilebda]

Hello Everyone.
Today I jumped on my scoot for the 1st time in a month. Noticed that the overheat bar jumped up to 3 flashing bars on my dash. I turned around went back home and noticed a drip from the waterpump housing. It also appears to be a hole of some sort as if a pressure fitting dropped out ot leaking. I should have been more aware few months ago when I saw everything getting dirty and wet with oil/fluid on the casing. Please see attached video. The cooling fan kicks in with no issues. Let me know what you all think my next move should be. Any info would be greatly appreciated.

Did some research on cyclepedia. Looks like the mechanical seal needs replacing.

Nice that these appear to be easily rebuildable!

Easy repair if you have tools at hand like, deep bearing pullers and a heat gun (pls see link, maybe helps). Take a whole repair kit, pays off.

Lay the sccot  on its LH side for this enterprise. Refilling coolant is easy when you open the SMALL hose until coolant apears.

Hi Ruffus.
Thanks very much for this info. Do they sell a repair kit? Or di I have to put one together via parts list? Can you let me know which part numbers that I need?

Thanks

[Ruffus]

Sorry, no part numbers. I take the whole kit from my trusted dealer. Its between €45,- to 75,- model depending.
People 200/300, Downtown 200/300 same kit.

Thanks so much for this Ruffus.
I order those parts. Looking forward to fixing.
Can you sterr me in the right direction to a deep bearing puller? I've searched AMAZON and loads of options.

Thanks

Well I can't say this fix was difficulty it was surely tedious. After all afternoon of working on this issue, I'm having difficulty bleeding the coolant system. The fan wouldn't kick in at all. The fan kicked in before the fix so I'm guessing that the fan and switch is in working order. What am I doing wrong with the coolant system?
Attached pics of the old seal.

Test the fan by shorting its plugged two cables  with a piece of wire.
Kicks in.  YES/NO
If NO check connectors on your temp feeler.
This sensor needs a pretty hot coolant to start the fan.

Thanks Ruffus. I will try that method.
Unfortunately my mechanical seal is still leaking. Looks like I have to go back to square one and change the seal again. I feel like crying. Lol.

[agilebda]

Ok so fan switch not kicking in. Changed the mechanical seal again and it's not leaking. Leaned the scoot on its side to bleed system and the fan switch not kicking in. However when the third temperature bar on the display pops up I shut the engine off. When the engine shut off I hear a gurgle noise as if air is still present in the system. I will do the wire test today to see if the fan kicks in as RUFFUS stated.

Refilling and bleeding coolant is easy when you open the SMALL hose down at the coolant pump until coolant apears.

Q: do you have the front part with headlight off to refill from radiators side?
Filling the expansion bowl only will not lead to sucess.

Ok I see. Yes the expansion tank has coolant in there. I will drain and try again. I have been taking the small hose off the Thermostat housing and waiting for a steady stream of coolant. I've been refilling the radiator yes. Perhaps my error is having coolant in the expansion tank. I will try again this evening after work.

If nothing else helps,

-take a waterhose
-put it on moderate stream
-plug/ hold it to/into the  small hose
-radiator plug OPEN
-rinse it tru for a while until system is full
(water running out of radiator)
-replug the small hose
-start /run motor for a few minutes
STOP motor
-open small hose let partly water out
-refill radiator with coolant
START motor
-repeat several times until coolant appears at small hose
