I'm just wondering what causes this water to rise and fall in the video below. I open the bleeder on the heat exchanger while filling it with water. So I know thats full of water. Is this normal operation? Or is there still air in there.
Water pump is wired to run constantly. The car is not running in this video, you are hearing the fans running. I forgot to shut them down. ![]() Thanks guys, DEF -------------------- ![]() I will return one day. |

It could be a couple things:
1. there is still air in the system 2. the mixture is too dilute, causing the pump to cavitate and generate bubbles 3. straight battery voltage may be a little high, causing the pump to spin too fast and cavitate like #2 (i dont know if the ecu controls pump speed or not when hooked up correctly) Id recommend trying 50/50 or throwing a voltage regulator in the wiring to adjust its speed. My W2A setup (stock st205) with 50/50 stays fairly level and doesnt froth up like that. |
