The following morning I started it up and drove straight to the dealer. Again the needle stayed halfway (normal), until I stopped at the dealer and let the car sit at idle (started to climb so I shut it off).
It turned out that the hose going from the radiator cap into the reservoir bottle wasn't seated correctly in the bottle cap, so there was a ton of fluid in the reservoir, but none of it would go back into the radiator. I think I may have pulled on it by mistake when changing my oil the day before :dunno:
You know what i think that might be the problem. Here's the setup i just got the resevoir from a dealership i still have to wait for the cap and the rest of the tubing to come in. So to prevent my radiator from puking antifreeze all over the engine i went to vato zone and bought a tube that went from my radiator and into the resevoir. Now i noticed just 3 minutes ago that when driving it was cool but when i stopped, it went right up again. So i got out the car and saw how most of the antifreeze was in the resevoir and none of it was going back into the radiator. Now is there something special about the OEM setup that makes the antifreeze go from the resevoir to the radiator and so forth? If so im gonna let my car cool off for a while then im gonna put the antifreeze that puked over back into the radiator and try to make my way to the graveyard to buy a piece for it.
