Sounds to me like your coolant system has an air pocket.

 

yikes

when its cold open the radiator cap, start the car then rev it a little bit and watch if theres any bubbles on top of the radiator. if so, your porblems is bigger.

 

2 things that i could think of. 1 blown head gasket, usually white smoke or bad thermal stat

 

no smoke coming from the engine-i just picked up toyota coolant so i added that to the tank, and i'm gonna fill up the radiator when the car cools down a lil bit. i was told that if there was an air pocket in the system, that i should start the car, once it gets warm, open the valve on the drivers side until just coolant comes out. that should force the air out, so i have to do that later also. this whole mess is just making me more and more frustrated. how can a service dept not fill up the radiator or the coolant tank, and not notice the temp gauge going to the end-especially after they did an 8 mile road test? i noticed the temp thing less than 2 miles from the dealership. they not only didn't see it, but they also had no problem giving the car back to me without filling the radiator all the way.

 

well... it would be coming out of ur exhuast and u would smell coolant burn thru the exhaust and if there is air pocket i would tell u how 2 do a drain and refill coolant remember to have heat on full blast and fill upper hose up 1st 2az motors are known 2 hold air pocket in it if not done right. last thing dont blame if anything happends to your car!! you could always email me or bring your car 2 jersey!! hehe again anything you do what i said i will not get the blame its ur diy work
