Question on Billman's coolant bleed method
The method: https://www.s2ki.com/forums/s2000-un...bleed-1067218/
Hello. New here, new to S2000s. Am I correct in assuming I only need to bleed it until the heat gets hot, and NOT necessarily until no more air comes out of the front bleeder? I bled it 5-6 times including two trips around the block. Every time I shut the car off, there's a little hiss of air from the front bleeder. When I squeeze the upper hose, a little coolant comes out and then I close it. The heat is hot. Scorching hot.
Long story: I had my mechanic flush the coolant and they left the radiator cap open.
By the time I got home (~15 minute drive) there was a huge mess under the hood and I lost almost a gallon of coolant. After letting it sit overnight I refilled it and bled it using Billman's procedure.

If the heat is hot, you are good to go.
The engine is safe to run, and any residual air will be purged naturally into the expansion tank. Make sure the hose going from the rad to the tank cap, and the hose leading from the tank cap into the bottom of the tank, is intact. This will insure air is not pulled back in during overnight cooldown.

This is why I diy. I hate paying someone to do something, only to have to clean up their mess, then pay for more materials, then do significant portions of their work over again.
Usually easier to just do it myself, usually way less hassle, always cheaper. Almost always superior results.

And half the time I can't even find anyone willing to do the work that I need done...

Damn, all those mechanic fail videos on IG just popped up in my head after reading this. Honestly hate to hear this happen in an S2K

Yes, it was very frustrating. But, all cleaned up now. And no harm done (I hope...) Temp gauge never got above 3 bars and it still runs normally, at least the limited amount that I ran it to do all the coolant bleeding.
