After checking DIY's help on how to change the coolant on my '08 i decided to give it a try. Since there is a valve and drain on the radiator i bought a hose to connect to it to minimize the spillage. Now here is my issue and question: As I was turning the valve to start draining the radiator it seamed the there was no fluid coming out of the drain even though i turned the valve at least 3 complete turns. I was a little reluctant to keep on turning and end up with the valve on my hand as fluid keeps pouring out. Am i supposed to keep turning the valve until it comes out of the drain? or am i missing something. Thanks in advance.
