Hello,

To do this all you have to do is fill your vehicle's cooling system from the highest point in the cooling system. How I fill my vehicle is to take the upper radiator hose off from where it connects to the engine block. I hold the hose up as high as I can and fill with coolant/water 50/50 mix. I keep filling until the coolant comes out of where the upper radiator hose connects to the engine block. I reconnect the upper radiator hose, clamp, and you should have no air bubbles in the cooling system. If you do need to drain the cooling system, there should be a petcock on the bottom of the radiator. Please get back to us with how things turns out.

Thanks,
Alex
