guys, i'm thinking of changing my gk76a coolant myself. like to know how to drain the coolant? is there a drain plug for it? where is it located? thanks.

Its on the side of the water pump, you MUST bleed this of any air after filling it back up or the bike can air lock and over heat.

VVS, how to bleed? where is the screw located? i know nuts but willing to try out myself...

If you find the water pump thats just infront of the front sprocket you will see theres a 10mm nut at the top front, you undo this and the coolant will come out. After you refill you need to loosen this a turn and air will come out followed by the coolant, retighten and jobs a gooden! DO NOT over tighten this as it is easy to thread due to the thread being slotted to allow coolant out.

thanks, VVS. i never had a chance to try as my coolant hose got leakage so rushed to workshop to had them changed & flushed.
