Alright a few days ago i notice a puddle under my car so i checked all my fluids..... my coolant was like 1/2 gallon low and been spilling ever since
the leak is coming from the back or underside of the engine somewhere... as far as i can see, there is no coolant leaking around the radiator, visible hoses, or even the reserve bottle.... does anyone know any other possible sources of leaking?

its kinda hard to get under the car, especially since its lowered, so i am trying to trouble-shoot before i take further action

 

The easiest way to find the leak is to use or borrow a pressure tester from a local shop to find out where its coming from. Maybe its coming from the weep hole. Good luck

 

Check your waterpump asap. If it goes your opti will more than likely be toast. It could be somewhere on the front like the waterpump, and driving is just blowing it to the back.
