It just wont stop over heating. I replaced radiator, water pump, thermostate, over flow container, new electric fan. I just don't know what it is that might be causeing the promblem.

Use a radiator pressure tester, see if the leak is the intake manifold gasket. Or do a block test, about 50.00, this will tell you if there are exhaust fumes in the antifreeze. In that case probably the head or head gasket!

How can I do a pressure test with no radiator cap? I can't go 2 miles without over heating or idle for 20 min. Do you think its that bad off already?

A pressure testing tool does not require a radiator cap, but if you are driving around without one, it could be your whole problem! Get a ggod I recommend a new cap!

It has a cap either on the radiator, or the recovery tank.
