Even i am facing similar issues. I bought my bike only yesterday. After riding for 5-6km, the engine heats up and radiator fan keeps on engaging long after using the killswitch. Especially in heavy traffic conditions, the heating is significant. What could be the problem?

hi all,

since the SVC could not detect the specific reasons behind my bike's overheating issue, i had replaced both the thermostat and the fan motor relay. since then, the overheating issue seems to have been solved as the overheating light did not come up any more and also the bike was not heating up that much. it was heating up occasionally, like in heavy traffic, but the fan was kicking in and it was cooling off...which was quite normal.

however, the overflow of the coolant through the drainage pipe has been there and, interestingly, it is evident only in the mornings. once i reach my office every morning which is around 5-6 KMs away, right after parking i see several drops of coolant flowing through the drainage pipe. and, it is not one or two drops, it is several drops every morning and there must be many drops while riding too. if this goes on, the entire amount of the coolant will overflow out of the reservoir...and, sooner or later, my bike will again start overheating.

could you please shed some light on this issue...i am getting quite depressed with this issue these days. please help.

regards.

You said that you have seen the radiator fan running while the engine gets hot, then why did you change the radiator fan relay??
Then the real culprit is the thermostat.

If the radiator fan doesn't work at all then you have to check with your relay, fan and wiring's.
