Default What size allan wrench sockets will I need to remove coolant plugs on the block?

Need to flush some sticky icky dexcool out of a newly acquired motor while it's on the engine stand. What is the size of the mammoth water jacket plug on the drivers side? Metric or standard? Also what is the size of the one on the pass side block? I need to go buy some size specific sockets tomorrow

Biggest I had was 3/4". It was a tiny bit small, but it will still work.
