Where does the coolant go!

[Pushit2.0]

You can use the hose of your compression gauge to perform a "leak down" test. You will not get a % but you can see where the pressure is going. Take the valve out of the part that threads into the head, same as a valve stem on your rim, then put the cylinder to TDC on the compression stroke, then hook your air hose up to it and listen/look for leaks, coolent, crank case, intake or exhaust valve seats is where it would be leaking from.
