I need to know if anyone is aware of the size freeze plug I need for a 92 sohc Accord. I am hoping that it just popped out and the block isnt cracked but I dont know what size to get...

 

It shouldn't have just poped out. They screw into the block on the back side by the oil filter. I believe the head is a 19mm. The thread is pretty big, but its also fine, like a 1.00 pitch. Why are you needing one in the first place?

 

Ok heres my problem



The cap/plug that seems to be on there isnt. And there is coolant leaking from there.... all I know is that its a problem

 

Still need help figuring this out...
