I just replaced head, head gasket, water pump, radiator, thermostat, therm sensor, mass air flow sensor, radiator cap, spark plugs and wires. My truck keeps over heating so we put in a new temp sensor that seemed to keep it in the okay zone on gauge, but coolant is mysteriously disappearing. No leaks on ground, no leaks on carpet inside, I mean like a jug of coolant every time me I drive five miles. When I open the cap it gurgles.
I just drove it up a kind of steep hill a quarter of a mile and when got to the top my tires were wet on the passenger side and opened hood the over flow was full and foamy, coolant was on the ground looked like it came from overflow reservoir.
Please help

You may have a faulty thermostat, the engine is boiling due to no or poor circulation. It may be a massive air lock, but check that the thermostat is working. Do this by removing and boiling it up in a pot of water on the stove, if you have a good thermometer you can watch the temperature for the correct opening temperature. This is normally stamped on the thermostat, start here.

Are you seeing any white smoke/steam out the exhaust? Was it doing this prior to all the work? From the description I would test the thermostat, and run a combustion gas test on it. It's possible that you have a cracked block or even that the replacement head is faulty.
