It's time to change the coolant in my 2005 yamaha yfz450se but I don't know how to do it. I was hoping there would be a drain plug on the radiator but after looking, either I can't find it or there isn't one. So how do I drain the coolant in the radiator? Do I just take off the bottom hose on the radiator? I would like to get as much of the coolant out as possible because I will be replacing the old coolant with Engine Ice. Thanks Breck.

 

got a drill?

 

Anyone?
