How do YOU bleed your cooling system? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I have an overheating problem.

Lower hose is cool but the temp gauge rises to the H pretty fast. I think its an air bubble near the thermostat.

I bled the system by opening the bleeder screw, filling until water came out, put a funnel in the radiator and ran it hoping it would burp the bubbles out.

But nothing happened, upper hose is warm, radiator is cold, lower hose is cold.

So, how do you bleed your system? I'm amazed about how hard it is to bleed this thing...
