Need some advice with a coolant change. I helped a friend with his CB650F (2016) that had a coolant leak coming from the thermostat case. So I replaced the rubber O-ring and tried to fill her up with fresh coolant.
I know about air pockets that can trapped in the system, so I gently put the first liter coolant in and gave the system time to let the air escape. Following the service manual (bleeding the radiator bleed bolt) tried to fill the second liter coolant in, but the radiator was full after I put in the next half liter. So I started the bike to bleed the system, but the coolant is coming straight out of the radiator. Long story short, I can’t get more than a liter coolant in her (I must overlooked something). This is not the first coolant change I did in my life but this bike is giving me a headache ☹️
