Gurgling Noise

[topher_]

Hey guys picked up an r32 gtr about a week and a bit ago and unfortunately ran into my first problem. The radiator was stupidly thick and had f**k all play between it and the fan and the fan end up getting stuck in my radiator and chopping a nice hole in it Anyway i ended up picking up a smaller radiator and fitting that, flushing the system adding new coolant etc. Now for some reason i hear a gurgling noise at idle, when i pop the bonnet i can't hear it in the engine bay.. only in the cabin. Sounds like it's coming from the heater. Any ideas on what it might be? Wouldn't be related to the radiator incident would it? Didn't hear it before that, maybe a coincidence?

Also when cruising my car might jolt once or twice (kinda like when you are running out of fuel) no idea what it is. When going up my driveway (steep) once the front wheels are up on it the rear wheels will start to spin even at the slightest amount of throttle Apart from that everything else on the car seems sweet

Sounds like air in the system, the air bleeder is near the pressure regulator and the balance tube
