Year: 2007 (European version but shares many of the same systems as US version)
I've just drained my coolant so now I have air in the system which I need to bleed out.
I've added the fresh coolant via the radiator cap and tried to massage air out of the radiator hoses as much I can before starting the engine.
I don't have one of those special funnels for this job, where the fresh fluid sits in there as you fill via the radiator cap with the engine running. So I've seen youtube videos where people run the engine with coolant filling up out of the radiator cap into this large funnel.
Given that I'm not equipped with one of these, should I:
- run engine with cap off? Can I cause harm by not being fast enough with adding more coolant once engine drinks some down?
- run engine with cap resting?
- run engine with cap on tight, then turn engine off and release air by removing cap once cooled down?
