So I recently did a timing chain, balance chain, waterpump on a 2011 malibu. Biggest pain on the whole job was the water pump. They make a special tool for doing it without removing the timing cover but I don't know as I'd want to tackle that. The waterpump bolts to the engine side of the timing cover and then there's a steel pipe that runs the length of the block to the thermostat. Getting that loose is an exercise in dexterity. When I pulled the timing cover off parts of one of the guides fell out. It was missing one guide bolt and 2 others were worn pretty badly. 
Got it back together and it runs pretty good. I believe the bolt that was missing was not reinstalled by someone else. Threads were good and with the access plug in there isn't enough room to back all the way out. I did fish around in the oil pan but didn't find anything.
