So you are suggesting I leave the cap off and let the coolant flow out onto the ground and engine? I wish there was a way to catch and reuse it. I wonder how much coolant would flow out?
Depends on how big the bubble is.

if you want to know if your pump is moving coolant , you could pull the rad hose off and crank the engine. if you drained and saved the coolant and refilled with water first , you wouldnt have to worry about the mess.
my bet lies with the thermostat
Even with a bad thermostat, should I not get heat to the inside of the vehicle? I will boil the thermostat and see if it works. It was working great before I changed the waterpump.
It should open a significant amount. Shouldnt have to look hard at it to know its open. Replace it and see if that fixes it before getting into the pump again.
I thermometer in the pot is helpful as well. Check the new one.
Thanks emac . . . I love my daily driver FJ40. Some rust, but otherwise looks good. I get more looks than most cars.
"2.5 containers of antifreeze"...Does that mean straight antifreeze?I just installed a new water pump on my FJ40 stock 2F, I put like 2.5 containers of antifreeze into it, I do not see any leaks, but it does not seem to be pumping water. The only hose that seems to get warm as teh engine gets hot is the major hose from the water pump to the T to the radiator. There is lots of pressure that builds behind the cap. No heat inside. Any ideas?

I always heard that 100% antifreeze can cause cavitation in the pump and restrict flow.
Just a thought.
Hi, Make sure you get the gasket and rubber seal for inside the housing. Mike
what Michael said! Make sure the gasket on top of the thermostat is present. Also, if the thermostat wasnt opening until boil, that is too late.
