this is something I just noticed. When I rev up the engine or take off, my engine temp gauge drops instantly to the bottom and then returns to normal. The last thing I changed for this to happen was simply replace a coolant line to the turbo. I spilled the mess all over the place (gravity) and just filled the rest up with water... (wasn't alot). Did air get in there or something? Had me worried when I went into boost and saw the needle drop like that....

 

Probably air would be my guess.

 

so when i hook up my coolant lines and i get air inside, what do i have to do? replace my whole coolant or can i just bleed the air or what?

 

I think it was air.. got it fixed.
