Does Your Gtr Sound Like It Is Boiling? Help

[iplen]

I have spent plenty of time around cars (Inc overheating ones) to know a bit about it, but..

After a little run I pull up and my r32 is bubbling and so on when you open the bonnet, there is no oil in the water vice versa, never looses coolant, never runs hot (sits a bit over half all the time) I have put a funnel in the radiator and let it run, loosened the bleed bolt, even when all I had done was check the color of the water on first inspection it has done this all the time I have had it... Which is about 18 months, do other peoples do this, I am worried about it doing a head, especially as my first event in it is next weekend, but I cannot find a thing wrong with it

What area of the motor in particular is the bubbling sound coming from or is it just the apparent sound from inside the cab?

[iplen]

Definately under the bonnet, from around the passengers side of the head moreso than anywhere else

Air in the cooling system. Specifically the heater system, was the heater on when you bled it?

My car's coolant, bubbles after I switch the car off. It has a greedy radiator and doesn't overheat - never had a problem with it.

Had the same problem for a while in my car. Used to bubble for a few minutes after 20-30mins of spirited driving. Never ever overheated though. Nonetheless, I bought a new radiator and its never happened ever again.

Heater has been both on and off, and the heater is super hot (another problem to fix, it is too hot and does not cool)

Squeezed the radiator hoses Ian?

Used a wooden dowel between your ear and whatever?

Had another suggestion of a funnel, letting it get temp up and then leaving it overnight, with the front up, it took a fairly healthy drink from the funnel and since then I have not had much of a chance to test it out, but it seems to be ok.... Will find out at the mount this weekend...

You'll probably find that it's the coolant in your overflow bottle boiling once the engine has been shut off, as it's no longer moving through the system.

Bingo, was not that originally, but is now, am in the process of putting a new radiator and thermostat in it... in time for racing it tomorrow and Sunday...
