So, I'm trying to figure out what's up with this mysterious cooling system of mine.
'97, 4 cyl, 5 spd.
Car runs fine.
When not running, coolant will leak from the lowest point of the lower radiator hose (well, not "leak", but since that's the lowest point the leak drainage encounters, that's where it drips from).
When running the system will not leak. The more full the cooling system is, the more it leaks. Fill it to the top, it's coming out the bottom the next time it stops.
Some times its a few ounces, some times it's many ounces (but not pouring out by any means).
Most often it will leak a few drops right after driving, then nothing. If left to sit for several hours, at a much later time (say, after 4 - 8 hours) it will begin to stream out much more quickly until the engine is ran again. It's like an odd delayed reaction.
I figured it was just a bad/loose lower radiator hose and replaced it last weekend and put on some new clamps (those factory clamps are a PITA when you're not near a proper tool box).
Same thing still happens with the exactly same pattern and frequency.
When I look at it, it looks like its forming right from where the lower radiator hose meets the bottom of the engine. It's like it's being forced out of that connection but I can't imagine how. Both the old and new hose is firm and connections were solid. Not sure if it's actually forming somewhere else and that's just where it's manifesting itself.
I'm in the middle of converting my 7 series BMW to a 5 speed from an automatic, so something as simple as a coolant leak that I'm too stoopid to solve is driving me nuts
