Icon4 leaking coolant behind engine block in straight beam!?

hey so i put some coolant through the radiator and it was pissing out the back end of the engine block. is there some kind of plug of some sort that could have blown out that is the cause of this or is it a blown head gasket ( i really hope not) i have the h22a4 engine and it is on the driver side of the engine block.

it is not clouding smoke out the exhaust and i also noticed my rad fans aren't working.

when i drove home to park it, it was revving from 1500 to 2500 rpm's constantly when is was hot and was hella overheating obviously due to the coolant not being present lmao

here are some gifs of the videos i took

well im unable to take another video with the fluids coming out now. these are the best that ive got. the leak is located on the backend of the engine block on the drivers side

in the video camera was facing like towards the front end of the car.




I believe the leak is coming from that bronze circle area but unsure exactly. Is that just a plug for the coolant then and I just need to get a new bolt or seal of some sort? Some help would be wonderful.

What about the O-ring at the water pump end of the water pipe leading to the thermostat housing ???

I would agree that the o-ring is a common issue to leak, but if I remember right that's on the passenger side of the motor not the driver side JRCivic1. It's been a minute since I've torn into one of those but if I remember right there should be a plug near the location you're talking about. I'm skeptical to think it would've blown out though as it's a threaded plug and not just a tap in freeze plug.

The water pipe runs from the thermostat housing (pass. side) to the water pump on the driver's side.

There is an O-ring on both ends of the water pipe... one very close to the driver's side where the block meets the water pump and the other close to the passenger side where the water pipe meets the thermostat housing.

The Honda part number is 91314-PR7-A00. You will need two of them. Coat them with Vaseline before re-installing.
