Please knock off the chit-chat and take it to the lounge. This is the a mechanical topic.

If you have a general idea on where it may be leaking and you can get at it, a rather low tech leak detector is to take talc, or some other type of powder, get it on the engine in that area, and check later to see where it'* been "washed" off.

When there is no external leak, dye tells you nothing. But now, we have an external leak that we can't track down. I would think dye could work this time if we can't find it without spending any money.

If it hasnt shown itself from the usual leakpoints yet (intake gaskets, coolant elbow, ect) check for a small crack on the front side of the radiator where the upper hose goes into it. You'll have to remove your air cleaner box. Over time this becomes a weak point because it stays relatively cool, then the thermostat opens up and hot coolant rushes through that hose hitting that spot on the radiator. Then thermostat closes, things cool down, then the process happens all over again. Ive seen radiators crack here many times, and people dont see it because it is hidden behind the air cleaner box.

Nerv...have you checked the level of coolant in the radiator to ensure you didn't leak out more than the pint?

With the cool snap we had in the area, it could be many things. I'd aim toward coolant elbow or hoses as a first look suggestion.

of course i checked the radiator, its full i lost about a pint, i replaced it, if it doesnt leak again im not gonan worry about it, if it does then i will

oh and im surprised at you for even suggesting such a thing motorhead:

"doc it hurts when i do this" "so dont do that"

"doc it leaks when i drive fast" "so dont drive fast"

that is not an option!

well everyone, i am confused, hasnt leaked again since havent lost and ounce of coolant, checked all my other fluids, good, what could possibly cause such a massive leake that it owuld leave a solid trail behind my car, and then suddenly stop and never show up again?

Rain.


j/k

It'* possible and I call these "technical difficulties" (because they are rarely explainable) that the temp went up after shutdown and pushed some out the overflow. Doubtful, but possible as the engine is still hot when you shut it down and that heat transfers to the coolant and there isn't any cooling with the waterpump and fans off.

It'* also possible that you have an issue about to manifest itself and that the temperatures were right for the beginning of manfiestation that evening. When things are right again, you will probably again have a leak.

My coolant elbow never had a problem. At the NY meet in October and a very cold morning I started it and the guys/gal told me.. I had a leak.
