534 overheats?

Takes about 1 mile for the needle to peg out at the H, and another half mile for it to start to blow antifreeze out. Both t-stats were removed today, and both open when put on the stove in water.... Upper radiator hose is stone cold.... We're sorta thinking that a hoist is going to be involved.... any other ideas?

A hoist to pull the water pump? Or has it overheated to the point of damage?

The hoist would be to pull the heads, if the headgasket on one side is blown, but I have no water in the oil, I don't see bubbles in the radiator, and it starts right up and runs like it should.

Turns out that there was a hose on top of the engine, near the front t-stat, for bleeding air. We thought that since the hose went up hill from the motor, the air would come out, and all would be good...... Turns out we were wrong, that a guy has to put the end of the hose lower than the water level, to let some coolant out, and then it's good..... Go figure. This thing has run real warm since a bigger (!) radiatior was installed, but with the t-stats out it now runs cool. That was beginng to get scary, but we haven't reached the end yet, cause the pump does move water (a lot of water) and it gets all foamy...... But it went about 30 miles round trip today, and all was fine.....

A very old mechanic taught me to all way's drill a 1/8 inch hole in the valve plate of the thermostat, this will insure air will never get trapped behind the thermostat, some factory T stat's come with holes already drilled.
