Exclamation Properly bleeding your coolant system

Thanks in advance.

You can either leave the radiator cap off and start and let idle till it sucks it down (might spill over though)
Or you can fill and cap radiator, then undo the screws on the metal coolant lines with a screwdriver.

Don't remove them just loosen a bit and wait for coolant to start to come out, then just tighten them back up.

Sorry, if you don't want to drain and just bleed the system (if you think you have air bubbles) I would just leave the radiator closed (top screwed on, capped, whatever lol) and unscrew the screws until coolant comes out.

Yeah you can just do a cold start and open them up and let it idle for like 5-10 minutes to reach its temp where the tstat will open and coolant will start to move.

Thanks in advance.
Next time, don't be so brief. It's there. Just bypass the drain/refill info.
