For two days there was a coolant leak coming from passenger side bottom corner, I can see vapor coming from beneath the headlight and a little puddle. The overflow tank was near empty. The last two days it seems to have stopped leaking as I didn't see any vapor coming from the bottom of the headlight and the coolant level hasn't dropped. I didn't use any stop leak product.

Good morning,

Coolant leaks cannot fix themselves.

Did you fill the tank back to level? The leak may have stopped from low coolant.

I would have the system pressure tested to determine the source of the leak. You can either rent a tester or have a parts store do it for you.

Once it is determined, let me know so I can further help you with the leak.

Had it pressure tested, turned out to be the water pump and S outlet located on left side next to cylinder head.
