Ya know where this "Metal pipe" is on the back of the block below the IM and it carries all the coolant inside the block?

Well that pipe that connects to the block is leaking and i was wondering if anybody knows how to plug it up? Should i use high temp caulking or like home depot bathroom caulking? There is also JB welding???


help?

 

No No NO NO NO!!!!!!!
The pipe carries all of the coolant from the water pump to the rest of the motor. The leak is coming from a split O-ring gasket. No amount of sealant will fix this. Buy a new rubber O-ring from the dealer (they are not expensive), lub it and install it. Replace the two (one at both ends) Easy fix just make sure you grease the O-ring so it doesn't do it again.

 

had this problem on my 92 accord...replace both number 12...part #91314-634-000

 

Also make sure you replace it as soon as possible. Aside from running out of coolant and overheating, you are also sucking air into the block which could stop the flow of coolant all together which means goodbye D15B2....
They are not too hard to replace, just make sure you do it right the first time and don't cut corners.

Based on the diagram above, you need two #12's. You remove the metal pipe by removing the two bolts from the thermo housing (#17,#18) and pull off the thermo housing #7. This is also a good time to replace the thermostate #3/4 while you're at it.

 

very easy to do just did last week

 

How can people be so cheap sealent isnt always the answer

 

Well i got the o rings and sealer but it still leaked. I started th3e car right away. Pretty sure that was a sputid mistake right?

JDM D15B now in my EF

 

Maybe u pinched the o ring will putting it in I've done it a couple times where it slips off and pinches and breaks

 

you're 100% that it's that pipe that's leaking? Not the IACV coolant hoses dripping down the block?

 

i just put my motor in recently and went to put coolant in and it was leaking out of this metal coolant line also how can i fix this what all will i have to take off to get to it?
