My car overheated and the radiator and thermostat broke. I replaced the radiator, thermostat, and hoses in my car:

92 Civic EX 4dr AT, 16 valve engine (don't know where it says 1.5/1.6 L)

After completion, car was running normally (not driven though), then I attempted to do a check for any remaining air in the system by loosening the bolt with the little hole in it on the engine block where the top radiator hose connects to.

The bolt, along with the cement engine block area that it was encased in, broke off. I can clearly see the water run through the hole.

Do I need a new engine? What other options do I have? I am a novice, some help would be greatly appreciated... though I think I do need a new engine.

 

cement engine block? I am confuse. To get the air out why the fuck didnt you just take off the radiator cap?

 

Thats what i did to remove the air. To check for air still being run through the system, I loosened the bolt on the engine block. The block did not come off, just the piece/area that encases the bolt, leaving a hole.

Bleeder screw, that's what it was.

 

I think at this point a picture is needed since your attempts to describe it aren't working out. If you just broke the bleeder then you can replace the port it's built into.

 

You are absolutely right! I got a chance to check it out again after work, and realized that the bleeder screw is part of a small port that attaches onto the engine via 2 10mm screws. I just unscrewed those off and 'lightly' banged the port off, no fuss.

Looking back (and the noob that I am at this), I had a completely different picture in my head when I wrote the first post and used the incorrect term: 'engine block'. Sorry for the confusion, and thanks for the help! Much appreciated; I really didn't want to have to buy a new engine and swap it... at least, not right now .

 

I knew what you mean right away surprisingly, that bolt doesn't really seem necessary in my experience with that car's cooling system, as long as you're close to level, but nothing wrong with trying to get as much air out of the system before you really bleed the system (w/ cap off or at 1/2 turn).

Just make sure you use a high temp. sealant/gasket maker when you attach the new piece to the engine.
