Radiator Flush now no heater is spotty

Fountainhead

Hi OP,
I recently bled my green coolant and replaced with Blue. I followed an Infiniti G37 video a mechanic (made in his garage) and had no problems whatsoever. After all was said and done I filled my reservoir at the full line and it emptied a small amount into the system after the change. I did nothing special, just a normal drain and replace. There are two screws to remove on the radiator endbells to allow each side to push out the air. I bought new O-Rings for these plastic screws and no issues at all since.
Sorry to hear you're having issues, and I hope you get it sorted out quickly.
