Default Coolant doesn?t drain from drain bolt? 2012 250 ec

Hi guys. I?m brand new to Gasgas. Just bought an almost new 2012 250ec.

I keep losing coolant. Not a lot but maybe half a cup full.

I?ve just bought some silkolene mag cool and thought I?d change what?s in it. The manual says to drain via the drain bolt on the water pump. I?ve taken the bolt out but coolant doesn?t drain out. Is this to be expected?

It would seem the coolant previously used (probably from the factory) isn?t as good as it should be. Around the neck of the radiator filler cap I?ve found some sugary type substance which stops the radiator cap sealing properly and is probably through the cooling system now.

Should removing the drain bolt allow the coolant to drain?
How can I drain and clean the system before putting fresh fluid in?
Anyone seen this before?

Thanks in advance guys
