‘96 Civic EX has pin hole leak toward one end of what I believe is “Hose, Bypass Outlet Part Number: 19508-P2J-000”.
Since it’s so close to end, would you cut out the pin hole and try to reuse hose or just go ahead and replace with a new hose? If replace, would get aftermarket or OEM?
I appreciate your feedback! Green X marks pin hole.
Definitely replace it. It looks to be swelled up because the rubber has degraded over time and become soft. Also check the other hoses. Try to re-use the spring clamps they work better than parts store screw clamps.
I would replace the hose... with a genuine Honda one.

I try and stick to OEM hoses so the fitment is correct, after market is typically not shaped straight hose that you have to bend to try and make fit.
Thanks to all!
Just ordered the Honda hose from local dealer. Will definitely try to re-use the spring clamps.
What about coolant? Owner’s manual says to use genuine Honda coolant and all they have is OL999-9011 “Type 2” blue, which is about $10 more than the green stuff I usually use but I’m thinking it might be a good time to go by the manual. That said, a buddy of mine with an ‘88 Civic hatchback says “the blue is not for our cars”...Hmm?
You can use the green stuff if that is what you have been using. Transitioning to the Type 2 (Blue stuff) is even better, but you would have to COMPLETELY drain and flush ALL of the green stuff out first before pouring that in.
If one is leaking, the others are likely in the same condition. It'd be time to order and replace all the hoses if you plan on keeping this car longterm.

So, it sounds like my buddy is wrong and the Type 2 (blue) coolant is not only for my car but a even better for my car than the green.
Yeah, I figured I’d have to COMPLETELY drain and flush ALL of the green stuff out first.
That said, I’ve read about the need to open a bleed valve/plug but I can’t seem to locate one.

I can’t seem to find a diagram and list of all the hoses in the either the service and/or owner’s manual.
Any idea where I can find a diagram and list of all the hoses?
I found the following 2 resources online, for flushing 1996-2000 Civics, a how-to article here on Honda-tech by @Pizzaman711 and a YouTube video by NutzAboutBolts2, but they’re a bit different.
Article says to drain the engine block by loosening bolt located on the engine block close to the oil filter, along with draining radiator and thermostat; while in the video he only drains radiator and thermostat.
Depends, are you wanting to do a full flush or just bleed the coolant.
Even then a full flush you have to find a way to push the coolant out of the heater core too.
Just bleeding you don't drain anything and instead just add coolant and burp the air from the system.
On my VX I drained the block, radiator, pushed air through the bleeder screw (I have a 92) and then used the hose with the heater set to max hot and blew water through the heater core.
I know we're supposed to use only distilled water but our water is so soft, the little bit trapped in the heater core is not significant enough to pose a problem in my opinion.
I then filled with the blue coolant to receive the full 5 year benefits of the extended life blue.

Yeah, I gotta try and flush out as much of the old green as I can to switch to Honda blue. That said, how do I push the coolant out of the heater core too?
Just picked up new hose from Honda. Damn, near over heated doing so, as I put in the last of my green coolant and lost most of what was in system making the 5 minute ride.
I’m thinking, the first thing I need to do is let her cool down and drain whatever’s left in the radiator, so I can remove the bad hose and install the new hose...?
As for draining the engine block, my buddy with the ‘88 suggested not to bother. He said just fill it with water, run the engine to mix it up and drain it. Do that a couple-three times to flush the old coolant out.
Thanks, I appreciate you taking the time to post those pics. I actually just found these in service manual.
So, I’m looking at the following hoses:
Top pic: (3 or 4?)
1) Upper radiator
2) Lower radiator
3) ATF cooler (2?)
Bottom pic: (5 or 6?)
4) Water bypass
5) Heater (2 or 3?)
6) Hose I’m replacing, which doesn’t appear to be labeled. (See red arrow)
That said, I know I already replaced the lower radiator hose and have the old one as an emergency backup, but I’m not sure about upper & others, will have to check my records. Hose I’m replacing (Red arrow)
What I did was to undo both heater hoses, one at the thermostat and one at the heater valve and I put my garden hose nozzle sprayer up to the hose and shot water through until it came out clear on the other hose.
My nozzle sprayer has a bullet shaped tip that was easy to press seal up to the hose.

Doesn't matter, which ever hose you put pressure to, the other will outflow. It's a mini radiator only and since you are behind the valve, there is nothing to prevent water flow through it.

Pin hole in hose, cut out or replace?
