Randy is spot on. If your block has been drained for any reason you can save yourself plenty of time and the potential of lots of grief to just spend two minutes drilling an 1/8" hole. Once the system is filled and the air is bled out the hole will serve no purpose and will have no effect on the cooling system. Two minutes of your time may save you $2,000.00 - $10,000.00 any questions.
