Anyone know:
- What the capacity of the TJ Rubicon 4.0L cooling system is? My Factory Service manual says 9.9L (10.5 qts), my owners manual says 13.7L (14.5 qts). I need to know how much coolant I need to add to get a 50/50 mix after flushing wih water.
- What size is the square drive drain plug on the engine block??? I just assumed it was a 3/8 drive, but that doesn't fit. WTF :-x What size is it and where can I get a tool to take it out? I can't seem to drain off enough water to add in even 4 qts of coolant using only the Rad. drain.
- Are there usually any problems getting air trapped (vapor lock) in the system when you drain and refill? If so, what do you need to do to prevent or purge the vapor lock?
Thanks!
