Does anybody know how to drain a gs300 mk1 rad and then how to bleed the system afterwards (or does it not need to be done)

cheers

I am still waiting for a replacement rad cap from lexus.. then I can take the car to see if i have warped the head or not With any luck its just something small

Jac,
why do you need to bleed it, have you got an air lock?
If so, there is an easier way than bleeding the full system.
I clocked that you've lost your radiator cap.

Steve J,

should be a self bleeding system
