Korean funeral tradition?

I live in California and visiting Korea in a few days to see my grandfather. The doctor says he will pass away today or tomorrow, which will be a day prior to my arrival. I am staying optimistic and hoping he will hold on a little longer so I can say goodbye. I read up on korean funeral traditions, but haven't found information on the specifics such as 'will I get to see his face one last time before 'they' take him away?' I know koreans do not practice embalming, but I'm still unclear of if they offer some kind of viewing. Please keep my family in your prayers... thank you.
