freeze plug coolant leak issue
 

My integra just started leaking coolant. A little plug fell off the car and it did have a spring attached to it but that broke off. I was told it could possibly be a freeze plug? It is leaking on the passenger side of the block behind the engine under the intake manifold. Anyone know what this could be?

It very well could be a freeze plug. Freeze plugs are designed to break out of the engine in the event that water begins to freeze in your block in an attempt to not crack the block. sometimes it works most times it dosent. . if you could post a pic up of the part that fell out and the area its leaking from i could tell you what it is.

i will tomorrow

Well, that's not the freeze plug that's for sure.

But um... I don't think that was ever supposed to be there in the first place?!

That does not look like anything I've ever seen come off a Honda, there is not much on the back side of a Honda block. Oil pressure, Oil filter, PCV catchcan box... that's about it.

Looks to me like someone was using it as a plug?

Not a freeze plug, but don't drive with a cooling leak ever. And I'm going to rant, I hate the term freeze plug. Although if you don't have anti-freeze and the water freezes they can pop out and save against a crack sometimes, but that's not why engines have them. They are there because in the casting of blocks and heads you have to get the sand out of the cooling and oil galleys,

Not sure that that is... can you take a pic of where it came from?

i wish i knew where it came from lol, but the leak has stopped, i replaced some hoses and stuff that looked worn out on the back of the block and let the car idle for two horus and it didn't overheat or anything so everything seems to be good now

You bled the coolant right?
