Loosen the two 10mm bolts and tilt the bypass valve actuator forward a bit.

Easiest way is to vacuum fill if you have a compressor. It’s how it’s done on assembly and it takes minutes.

Otherwise check my thread on bleeding the VZ and VE V6 in the How To forum. It’s the same procedure I’ve used since the mid 90’s and it’s always performed better than air bleed screws etc. Was taught to me by a Holden technician.

Same method is now seen on all sorts of cars and you can buy proper bleed buckets.

Hope it helps. It will get most of the fine bubbles out.

I say all this assuming the water to air intercooler is connected to the rest of the system.

If it was a water to air plate, it would have a separate res for the intercooler fluid.

The bleed screws are meant to be used with a bleed bucket. You fill the bleed bucket open the screws turn engine on drive check fans and level job done.

I use vac bleeders at work much easier.
