I just recently got my 1985 Prelude running, I took it off the road becuase back in june I noticed I had a severe antifreeze leak and i parked it and was going to get rid of it but couldnt bring myself to, anyways, it starts leaking once it reaches operating temperature, its not the water pump im nearly positive, behind the waterpump where it connects to the engine there appears to be either a bar or a hose coming from directly from behind the water pump and I think thats the problem, I cant see for all the vacuum tubes, but can anyone tell me exactly what that part is? Its not the head gasket leaking because the leak is coming from about an inch away from the head, where that hose/bar is at, i can see about 3 inches of it and i cant tell what it is, its about a inch thick and appears to come from behind the water pump, any help would be REALLY appreciated

 

Thermostat?

 

I believe there may be a o ring that seals that metal tube on the water pump end. I believe your referring to a metal tub that runs from the pump to the other side of the engine? I am not 100% sure but a service manual could shead some light or even parts diagram.

This diagram shows the tube running to the thermostat housing. Do this look familiar? There is a heater hose not to far from the water pump?

yea its a tube running directly from behind the water pump to the other side of the engine, this will save me a buttload of money if thats what it is cuz i thought it was the head gasket at first til i looked at it a lil closer, i didnt see the water pump in the diagram, its a 1.6 SOHC, that link goes to a heater unit, but i might be blind, I didnt see any hoses that looked familiar as far as i can tell, i misplaced the manual so im prob gonna end up havin to buy another

also I replaced the thermostat a month before it broke down so im positive it isnt that

thanks for all the help

btw ill take a picture of it tomorrow and post it maybe thatll help
