So I was driving my car and coolant started spraying out of this little hose, then the engine temp went waaay up. so i said ok let me put water. Did that and it got me home (a few blocks away). I know i have to fix that hose, BUT when i filled it up a night then checked it in the morning it was dry again. And that little hose only leaks under pressure.

This is the little hose that leaks:





its behind the valve cover, connected to the intake manifold.

So Im not sure why it also over night. And last night i filled it up and this morning it was full. But then i drove it and it sprayed all out again.

 

thats cause when the car gets hot it presurizes the coolant then it sprays out. its probably a tiny hole thats why it doesnt leak when not under pressure. just get a new hose and call it a day. i bet you could even just cut that hose down a little and it will work.

Oh yeah I know I have to replace the hose, but you see when i fill it up at night it will be all gone by the morning.
