I just noticed this stain under my car last night. This morning I checked and it was dried out. No smell or residue on fingers when touched. Checked engine fluids and everything seems ok (didn't check engine oil as it doesn't seem to be an oil leak). The only odd thing I noticed was that the coolant reservoir
cap was a little loose. Any ideas?

 

Looks like AC to me. No smell, no color, no worries.

 

Looks a little too excessive for AC....maybe someone dropped their water.

 

Any chance the stain was there before you parked? This reminds me of a joke a friend of mine played on someone who had proudly rebuilt the engine in his car. My friend snuck outside and poured a quart of oil on the ground under the engine. Poor guy about had a heart attack thinking his fresh rebuild was puking oil.

 

Ok, but the stain is dry and didn't evaporate overnight.


I thought about that but stain is dry...


I noticed the stain last night, it wasn't there before. To me the placement seems just too perfect to be from another source.

 

Just checked under the car in parking lot at work. Nothing, not a single drop. All fluid levels normal.

 

Maybe it saw something really really funny and peed a little

 

But pee smells... don't it?

 

Only if you get down on the ground and almost put your nose in it


Maybe your turn signal lubrication leaked?

 

Not if you've just had asparagus.

 

Could be. Or maybe it's horn coolant.
