After coolant change I get leaks from the weephole but WP already replaced

[Corrosion]

I went to do a coolant change, the same stuff I have been using for a while and never had a problems with (it's silicate-free). I took one gallon out, and I put one gallon in. I put the funnel on. I ran the car until there were no air bubbles. When I drove it today I was checking for leaks. I saw a new leak. It was a coolant leak, I traced it down to some holes on the engine block.

It's dripping down there. But for some odd reason, according to the research I have done, it's to indicate that the water pump is going bad or the seal on it. That doesn't make sense since because I replaced the water pump last year 2024.

This was the kit and the only thing I didnt use in it were the belts. I bought them oem. But it does have quality parts in it, including the KOYO bearings. I'm confused why the water pump would be leaking.

Could this be some other issue? I didn't seem to overfill it, there is no extra coolant in the reservoir. So I'm confused.

Holes or hole? Is it leaking below the timing belt cover? If yes and not somewhere else, then it's the water pump. If the OEM water pump is available go with that.

It's one of these holes. It's not coming from the timing belt cover.

It might be leaking down onto those from above, not sure. It doesn't make sense to be coming from those holes. They should be plugged. That looks to be on the back of the engine block so it's definitely not the water pump.

It turns out you were right. I think I found the part number. It's the 19505-PT3-A00 Pipe.

I think the pipe connector goes to the water pump and to the thermostat? Does this mean I have to remove the thermostat housing just to disconnect this pipe? How hard is this job?

Looks to be a rubber hose puncture in your picture. I would replace all those water hoses. Mine have busted and left me stranded before. I think the pipe you are asking about is #12, which isn't what's leaking. The rubber water hoses aren't in the diagram you posted. Some are a pain to replace given the location like the one in your picture.

Alright, I got a new problem. I had to buy a thermostat housing thing, because the honda parts charts part didnt show that there were two bolts under it and it was so cold out I thought it got stuck, so I broke it. So I ordered a new part but something is odd is going on. Because it's not matching. Will the 90 honda accord thermostat housing work with the 93 honda accord thermostat housing. Because there is a difference.

Update: Nevermind, I think the part is going to work. I did get everything together. I missed a ground strap under the thermostat. I totally forget I tucked it under there. And car wouldn't start. But it seems to be working and no leaks. I'll take it for a test drive later on. The part numbers are Honda 19320-PT3-A00 Honda 19320-PT2-000. I'm not sure what the significance of this change is. But the distributer has a little holder that goes on the valve cover, and then connects to the thermostat fastener (on top, look at the picture) on the other side. I think its suppose to keep it stable. And the passage way is a tad bigger and different.

And also, 4cyclepower92, you were right. the piece of rubber on the hose at the end has a little hole in it (hidden by the clamp). And my water pipe did have a pinhole not near the nipple but to the left of it. There are 3 bolts that connect the water pipe for the thermostat housing. It does come off easy on the top. On the bottom, you take the oil filter off, just tilt it quickly vertical not to spill. There you access the bolt. The bolt did not break or anything. Which was surprising. I could not get the water pipe out with my bare hands from the water pump. I just used a pry bar to pry it out. This job was not suppose to be that difficult. My only mistake was missing those two bolts on the bottom on thermostat housing.
