Took the entire scoot apart. Found a few cracks in the cooling hoses. Decided to change them all! Scoot runs fine now. Thanks for everyone's input.
I have that check engine light that wouldn't go off. Could the system need resetting?

Hi guys, came across this on ebay. I wonder if this fits inside in the current speedo dash. What are your thoughts? If it did, would be a nice aftermarket add on.

Hello Guys.
Thanks...the only thing I did not try was the thermostat. I will do this today and let you know my findings.

« on: January 23, 2025, 06:49:17 PM »I have no experience on scooters like your's but you need to make sure all hose clamps at the scooter's cooling system are still tight.
Hose clamps on rubber hoses tend to loose tightness over time and this causes water and air leaks at the cooling system. This causes air pockets which disrupt effective coolant flow, which causes uneven heat distribution - and this can cause a cooling fan to come on for a short period.
This actually has happened to my Silverwing. Some hose clamps have lost tightness over time and there were small water leaks. So small that I never noticed a coolant leak - the coolant actually evaporated due to engine heat and I never noticed anything.
When the engine cooled down afterwards air obviously got sucked into the cooling system at the hoses with loose hose clamps.
All engines normally run warmer if cooling systems are not properly pressurized. And loose hose clamps surely cause lower pressure and overheating problems at any given engine.
So hello guys. Decided to give it a try again today. The bike heated up within 1 minute of idling. Never seen this so fast. I tightened up all clamped hoses. Gets to normal operating temp within 45 seconds (2 bars) then goes to 3 bars within 60 seconds or so. I'm inclined to think that it's a head gasket job. What are your thoughts?

Hello All. Well happy new year to you all.
I gave it a try again after flushing the system with a medium pressured water hose. The fan motor kicked in at 108 degrees. Exactly what I was looking for, however it only kicked in for a maximum of 7 seconds. Could it be air still entering the system? I will tighten all hoses again and try.

Okay...so I've tried everything that Ruffus has stated and suggested. That fan still wouldnt kick in. How do I know if the head gasket isn't or is blown and needs to be replaced? I don't see any coolant dripping from the head gasket area. This is the only thing that I can think of which will prevent the fan switch kicking in.

« on: October 13, 2024, 11:21:53 PM »My last straw:
-is your repaired coolantpump really working?
There is the chance to block the impeller/bearing by wrong mounting or too much pressure when installing.
Is there the possibility something got into a hose, a piece of rubber etc.?
Open the thermostate housing, take the thermostate completely out, close again and try (pls see pic)
Hello Ruffus. I will give this a shot. I'm pretty sure that the pump is working fine. When i revv the throttle up when bleeding the coolant, the stream pisses out stronger as the rpm increases. I have a new relay on the way. I will give it a shot with cleaning out the thermostat . One thing that I noticed is when the coolant gets hot, the radiator is cool as if the coolant isn't flowing through that area.

Tried everything with no luck. Extremely difficult to pop that bleed screw or hose back on when the coolant is boiling hot.
I changed the thermoswitch. New relay. I'm stomped!

-connect them with a paperclip or short piece of wire
-ignition on
-fan kicks in?
If YES, your thermoswitch needs to be renewd.
With interchanging relays I meant, change horn relay with indicator, or otherwise to see whether they are ok, as far possible from connectors configuration.
Thanks very much. I understand now. Will give this a try tonight.

Thanks Ruffus.
Checked the fuses today and all were fine. Not quite sure that I understand you on the relay paperclip test. Can you show me with this diagram attached?

Ok Ruffus and Everyone.
Took some time out of my schedule to further work on my scoot. I bypassed and ran wire direct to battery from fan and it kicked in. So my best guess that it can be the relay or thermoswitch.

« on: September 26, 2024, 03:43:02 PM »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.

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.

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