i have a 04 Sienna. The van was running fine until the starter went bad. But before that in the winter it wasn't heating very well. So while I was putting in a new starter I thought I would change the thermostat. i removed everything including the starter which made it easy to remove thermostat. Replaced and put it all back together. Car started fine but after driving about 5 miles i noticed the car overheating. I took everything back apart to the thermostat back to advanced auto parts and exchanged it for another. Put in the new part with gasket and started it back up. The hoses were soft both top and bottom. I filled everything back up with fluids and left the cap off for a while. I noticed the coolant started to overflow out radiator housing at cap. I replaced the cap and noticed it got even hotter gauge rising and both hoses top and bottom rock hard. The thermostat was installed with cone facing outward toward driver side fender. What could be the problem. It didnt overheat until I installed new thermostat. It is like thermostat is not opening. help please....I'm getting good at taking the thermostat in and out.

did you burp the cooling system?
looking the thermostat, the spring side goes in first, otherwise, you might have installed the thermostat backward. I would normally buy the thermostat from toyota stealership, about $13, and a new $2 thermostat gasket, and after refill the coolant, run the car idle for 30+ minutes with heater on max, and fan on max speed.

I ran the car on max heat with the fan on high. Do i need to leave the caps off when doing this. Spring side goes in with cone side pointing out or into housing. on the housing there is a sensor which appears to have a place to connect a wire. I can't find a wire to connect to it. Also could someone post a picture of how the thermostat should go in. It's got to be the thermostat everything was ok before I changed it. Well except for the starter but that is working fine after the replace.
bronzemaxell is right. you should have bought the oem thermostat instead of third party one. It is cheap and critical parts. I would always go to OEM.
let me clarify on thermostat, the spring side goes into the engine,

Did you resolve this problem? If not there is a small water line the goes from the thermostat housing to the throttlebody. Disconnect that hose from the throttlebody to allow the air out. Also I found it helpful to purge air from the water inlet over by the ac compressor. Remove the hose clamp and carefully work a dull flat small screwdriver between the nib and hose. If you lift slightly, you will hear air escaping.
