i recently installed a mishimoto radiator and shroud in my Z, filled her up and had no leaks. drove the car to work a few days, but the last 2 days i had issues. the drive home is all highway until i get off on the ramp and make a left. each time i got off my temp would jump from the normal "slightly below mid" to "almost max" and the needle bounces around a bit before finally going back to normal. to make it better my heater would start blowing cold air. i feel like i am not actually overheating because the needle jumps around faster than coolant could possibly cool off. (takes probably 1second to go from overheat to normal)

safe to assume i have bubbles in my system somewhere? im guessing the left turn is putting air through my temp sensor and heater.

 

How did you bleed the system? There is a bleeder valve in the back passenger side of the engine bay, close to the battery compartment.

 

 

wow i feel like a tard.

been doing watercooled computers for years, i just assumed that as long as water is moving it would bleed all the air bubbles.

thanks man.
