Yamaha Xmax(YP125R) Thermostat and Coolant Replacement

[@alexmentzveligia8345]

Thanks for the video, Is your radiator fan also going on, or only was overheating?

[@pullumoto]

Yes it was also going on and the temperature wasnt dropping

@@pullumoto did it solve the problem? Mine overheats as well, but I suspect thermostat works. I think my radiator it’s the problem. It’s dirty

Ciao Pullo, I have noticed my radiator fan doesnt start, engine gets to hot quickly, so whats mostly the issue, Coolant Temperature sensor or the thermostate!?

[@pullumoto]

First thing I would check is the oil, check that its not milky and contaminated with coolant(just check from dipstick) If it's clean oil I would check coolant level and thermostat. You can test the thermostat easily in a pot with boiling water and you should see it open.

Pullu if I don't bleed will the thermostat and the pump still work

[@pullumoto]

yes they will work but there is a great chance of coolant bubbling and overheating

[@dejunfrancis4162]

@@pullumoto my bike was working just fine but dismounted to respray after mounting I realise it's not cooling but I didn't know about bleeding and noticed the hose are empty which means water did not come through so I was thinking if it's not my water pump or thermostat

[@pullumoto]

In that case I would refill the coolant (near battery) and also the reservoir (under footrest) as it seems you do not have enough coolant

[@dejunfrancis4162]

Should the hose carring the water get hot my fan now goes on and off properly the needle stay steady in the middle is this a sigh that it's all good.if so thank you so much for putting up this video

[@pullumoto]

all hoses should get hot after a few minutes when the needle is in the middle(it should stay around there that is good)

A mi se me calienta la moto cuanto salta el ventilador he limpiado el liquido refigerante pero seguiré purgandolo salio mucha mierda lo purgar otra vez a ver porque me se calentaba la moto a ver si es que estaba sucio o es el termostato o la bomba del agua, un saludo.

[@pullumoto]

asegúrese de que el refrigerante esté limpio y no tenga sedimentos y siga enjuagando hasta que esté limpio. También puedes probar un termostato quitándolo y metiéndolo en agua hirviendo en la cocina y verlo abierto para asegurarte de que funciona
