I have a leak on my 05 honda civic, I wanted to think it was the water pump but when I go to pour in the coolant, it leaks like a faucet from the back of the engine but when the car is running and has some throttle, it turns into a drip. Could it be the hose that in the back of this diagram that is near the water passage? (right next to the intake)
Where does that hose head to? I can’t quite get my car jacked up high enough the standard jack I have, so I might need to get a floor jack rented somewhere or put it on a hoist. Just was curious where that hose goes and if that could be my culprit.
Thanks ETCG!

There is an ‘o’ ring on that pipe that could be leaking. Easiest way to find a coolant leak is with a pressure tester. These can often be borrowed from your local parts store. Also, they aren’t that expensive and handy to have around.

I did figure out that is where it was leaking from, so I took the connecting pipe out and I ordered the o-ring Honda OEM replacement, part 91314-ph7-003.
However, when I slid the new o-ring onto the connecting pipe it is loose and seems slightly big. Will it tighten up when I push the connecting pipe back into the water pump housing? The way I got the pipe out was from the side, I didn’t want to remove the intake again, so I am just going to try to press it in. Thanks again for the answer previously and this will be my last question. I guess I can just try to slide it back in tonight and see if it stops leaking haha.
