Frost plug removal help
Hi guys I was looking for some tips on frost plug removal so I can install a block heater. Did a little searching and couldn't find any conclusive info. What's the best way to get it out without getting metal filings in my cooling system? Also I've heard there are more than one plug, should I remove a certain one and lastly do I drain the system first and how much antifreeze will it take to refill? I bought 2 gallons.
