i ran cleaner though my f150 toclean the cooling system. It said to drive the truck for 8 hours with the cleaner and water in the system. I ran it longer than that and it started to overheat on me while sitting in traffic. When i checked the resivior it was bone dry. It has did this one other time with antifreeze in it this summer, but i only drive the truck on the weekends, could this be a head gasket craked block or what else could be the problem and is there anyway of troubleshooting this myself?

 

Check your oil dipstick, see if it looks like water is in the oil or antifreeze, if so then you have a blown headgasket

 

Try useing a cooling system pressure tester to find leak and problem.

 

or you could put a dye in your coolant and then get it checked with a black light
