Massive coolant leak/geyser out of nowhere after fixing misfire??

The heater hose bleed valve splice have been known to leak. That's is where the green cap is in the video. The very back of the motor. You have a couple of connections there. The hoses for the throttle bodies for one.

I think the heater connector is completely gone, like you said. It's just replacing this part, filling coolant back up, and try to bleed air bubble by leaving engine/heater on with reservoir cap removed?

Wonder if the Z1 aluminum replacement worth it for almost 30 buckss

I have the Z1 part. That's where my aftermarket water temp gauge sensor goes to.

They don't have the one with bleeder screw in stock until Feb...I think I'll just get the stock plastic part so I can fix it for now.

You burp the cooling system by leaving the radiator cap off and letting engine warm up with heaters on, correct?

You can do it that way. It will take a while.

Any tips on getting the spring clamps off the hoses and broken pieces out of the hoses?

Those spring clamps do not wanna budge...hard to fit a vice grip in that small open space. My hands scraped up trying to get those clamps off to get the broken pieces out.

Remove the cross bar and the throttle body for more room.
