I read the instructions. I used a turkey blaster to remove the coolant from the radiator hose. The first time, while I was pumping it, it seemed to be going as advetised until the coolant got in, so I removed it, shut the car off and saw the coolant had rise back up quite a bit. I washed out the block tester, dried it and tried again. Repeat steps, had used the turkey blaster again, but this time, I didn't even touch the thing, I left the block tester in the radiator opening then took my attention off for a moment, looked back, and the whole thing was full of coolant and started squirting out the top. I shut the car off, checked and now the hose is completely empty. What is going off here? I am checking in the first place because a few days ago, I got home and while unloading, noticed coolant spilling all out underneath.
