First of all, thank you Dave for your quick response.
I did it this afternoon (the bike wasn't running with water on the radiator after all, but i replaced the coolant anyway).
I live in Portugal, and i think that it should be VERY difficult to find the water wetter :sad:
I did all the steps covered in the service manual (drain pipe, bolt on the block, released the air bleed hose) and i think that everything's ok.
After reinstalling these elements, i started filling up the radiator up to the filler neck. While i was filling it, i saw some air bubbles coming out of it ( radiator filler opening). Then (when the coolant reached de radiator neck), i installed the RADIATOR cap, and filled up the reserve tank (a little more than the max line as i couldn't see it) at that point.
I started the engine (without the reserve tank cap), let it iddle for 3 minutes, snapped the throttle 4 or 5 times...and i didn't noticed any drop on the coolant level ! I stopped the engine, started it again, snapped the throttle and the coolant was at the same level (a little above the max line).
Then i let it iddle until the point where i know that the fan should start working (on the temp needle gauge), the fan started working, but the coolant stayed at the same level.
I drove the bike for a while and everything seems to be ok, but i have three questions:
- Is there any possibility that there is some air left in the circuit (as the coolant level never dropped) ?
- Is it normal that the coolant on the RESERVE tank doesn´t get hot, even after the the fan started working ? (naturally, at this time you can't almost get close to the radiator, or the large radiator hoses as they VERY HOT - doing their job - but the reserve tank is almost cold)
- Is there any problem to have the reserve tank coolant level a little above the max line ? (It's really hard to see the level in that milky white tank), unless you get a special light angle).
Thanks a lot for your help, Dave
