Trying to battle this coolant issue that's leaking under the car. It doesn't leak directly below. But I notice there's some on top on passenger and driver side. Under the car it's by the mounts too.

On the shields it's directly straight down on both passenger and driver side.

No milk oil cap or oil at all.
No smoke coming from exhaust.
Car hasn't overheated after a two hour drive.
coolant keeps disappearing but leaking as describe below. I had to fill the tank three times with 1/5 of a 1 gallon tank of antifreeze.

What else should I look for?
The car has 46k miles for an 07.

My bet is (in this case) it's a defective radiator cap. They do breakdown over time and a new one usually solves a "mystery" leak like this one...

 

Did you lose your last thread?

Put it on stands, remove the splash guards, clean it up, and pressure test the son of a *****. Sorry to be harsh but use common sense.

Or pay someone to do it if you don't know what your doing. Which in that case these threads would of been a waste of time anyways

 

ended up being the radiator itself. It only manages to take 1 gallon of antifreeze so far but I'm topping it off as I go, since it's running through the system. I accidently posted twice because I thought I posted it in a different website
