coolant system pressure. Any Help?
 

My coolant system is emptying the radiator into the overflow bottle. I assumed that would be a water jacket seal allowing exhaust pressure to pressurize the system and press the fluids out the radiator into the overflow bottle. Any input?

It could be a bad cap

didnt even think that. I over looked the obvious. Thank you I`ll ckeck it out

Look under your cap if the rubber seal is gone or corroded it needs replacing

auto parts stores sell them for about 15 bucks

next thing you might want to try to get that "my water jacket is blown" thinking is to do a pressure test in you coolant or remove your spark plugs and injector fuse
and crank your engine if you get water spewing out you spark plug holes theres a sign of a blown coolant seal

other signs are OVERHEATING and TO MUCH WHITE SMOKE

Thanks, I got the white smoke but only at a load.
