Okay, so that DIY was super helpful. Here is what I discovered. My intuition was correct, those lines were meant to connect to those two ports on the engine. The reason why the shorter one in the first picture wouldn't connect was because it was the wrong tube. The tube that connected to the bottom port was too long, when I tried to connect it where it was supposed to go, it kinked up the line, and that shorter line barely reached that top port. I had to disconnect the third tube a little deeper done, and lucky me, coolant started pouring everywhere, but I was ready with the shorter tube I pulled off, and stuck it on there real quick. It connected perfectly. The hardest part was pulling all of the tubes off, they were super stubborn, and that third tube down a little deeper was the worst one to get off. My coolant was low, and my reservoir was, as far as I could tell, empty. I guess because everything wasn't connected correctly. By any chance, is there a possibility that I can hold the body shop liable for not having everything hooked up correctly? That third line was connect in the wrong place, so I don't even know what my coolant was being dumped into, and of course those first two tubes that I posted weren't connected to anything, and that bottom port on the engine was where that third coolant line connected to. Fortunately, I had some Honda coolant left-over from when I did my coolant flush, so I was able to fill up my reservoir, and top off the radiator. My main concern is what damage may have been done to the engine. I'm guessing I should still take it to a mechanic? I fixed everything and have it all connected properly, but I am worried about what effect this may have had on my engine. Thank you again for the super helpful response. You're a lifesaver.
I recently started doing all of my own mechanical work on my car. I got in an accident back in April or May, my car, a 2012 Honda Civic Si, hydroplaned and I hit a guardrail, and messed up my front end, however mechanically it was fine. I didn't have collision coverage, so I paid for it out of pocket. I decided that to help save myself money I would start doing my own mechanical work. I recently changed my MTF (oem honda fluid), my oil and filter (Amsoil Signature Series w/ oem honda filter), flushed my coolant and replaced with oem honda coolant, changed the spark plugs and in NGK spark plugs, replaced my engine and cabin air filter, and changed my pcv valve. I'm doing a lot of this work for the first time, and I'm super excited to be doing my own mechanical work. I discovered that my engine outtake (maybe intake?) was not connected, so I fixed that, then I found a hose near the engine not connected to anything. I'll post pictures. Can anyone help me figure out what these lines go to? I don't know if it's the reason my car has been idling rough, but I can also post video of that, it it helps any. The mechanic said it might be a coolant line. I cannot figure out for the life of me what they connect to, as they don't reach anything. Thank you.
in the old 8thGen Civics everyone that lived in warmer areas of the country would do this. I ran it similar to thins on my old 8thgen for 60k-70k miles with no issues.
