Hello everyone, I am newbie here and I own an ninja 250R yr2010, I just changing my coolant here (following standar procedure in service manual).
I drain the old coolant,
Drain the coolant from reservoir tank, then
I put a new coolant in till the filler neck and full line in reservoir tank!
then I purging the air using normal procedure (running the engine with radiator cap OFF).
After that, I put the radiator cap ON, and then running the engine till the radiator FAN swings!
voila, that should be done, then I open the radiator cap, check the coolant level,and found the coolant level is dropped a bit, then I add a small amount of coolant to get to full of filler neck.
and then again I warm up the engine (this time by riding it around my neighbourhood), stop and wait till cold, then open the radiator cap again, check the coolant level, I just shocked, AGAIN, why the coolant level is again, dropped a bit??
Here is the picture of the level where coolant dropped a bit :
more close up pict :
Even so , the level of coolant in reservoir tank is just fine !
the view when reservoir cap off :
Please help me, is the level of coolant normal? Does this happen to everybody? Thanks btw
