Two steps forward and a giant leap backwards.

There is barely any antifreeze in the system. Most of it is what which is odd. I did notice the Penn oil had a strange color when it was going it but it didn’t look like that.
I am taking this to mean barely any anti freeze in the cooling system? If so its going somewhere it doesn't evaporate like water or whiskey :) get some at wal mart or something, if you want the best deal get the 100% concentrate and mix it 50/50 gets you 2 gallons that way. Premix is a rip off IMO. top off the cooling system, get a pressure tester, you can rent one at a chain parts store like auto zone and do the test. This will tell you if you need to tear the engine down and reseal it. running it will only wipe out bearings and lead to an overheat etc.
