Okay my swap is finally done and i just started up the motor but I need some help. The top of the radiator and the top hose is hot, the gage reads a little over normal and the car is blowing regular air. a few mins later I noticed steam coming from the radiator cap. The bottom hosse is cold not even warm. Does anybody have an idea whats goin on?

 

Is the thermostat in backwards?

 

I have no idea, but thats where my heart is too cuz when I first got the motor i replaced all the seals including the seal that goes around the the thermostat so there is a possibility

 

Also check your heat and see if it is getting hot and working correctly. If not, I'd be leaning towards the thermostat. Or something else could be clogged up.

 

everything on the car runs like brand new up to the day i pulled the GE out of it dogg. I'm about 85 percent sure its the thermostat. what I did to make sure was I just pulled the Gs motors thermostat housing out to see what it looks like in there. so tomorrow when i get home from work I'll pull that housing off the gte and take a look @ that thermostat. Other than that I love the sound of the wastegate

 

its probly that.. i had the same problem.. If its a arist 2jz with the hydro water pump i suggest a supra TT water pump conversion.. $167 from toyota and its so much cleaner and better.. less headache.. i blew 2 aristo hydro water pumps on my aristo swap before i switched

 

Oh I swaped out the hydro water before I had the motor put it. I guess there were air pockets in there somewhere. What I did was let it sit over night with coolant in the funnel by morning the level drop big time when the air worked its way up and out of the system. Never got the overheating anymore.
