Hi guys Just wanting to know my best course of action here. Today when I got home I noticed a small coolant leak coming from where the hose connects to the bottom of the rad. The hose was loose and as I forced it back on and better secured the connection, I managed to get a spraying of coolant across the garage. I'm not sure how long this small leak was going on for but id say I lost at least 100ml when it shot out. The levels in the bottle seem fine, still sitting well above the low mark. My concern now is how can I be sure I haven't introduced any air in to the system. Can I run it with the small hex bolt on the bottle out to release bubbles if there are any?? TIA??
