I hate creating so many dam threads(yes I do search the forum before making one lol) but I got a funky coolant leak going on. The leak is towards the back part of the engine (I can tell because When I look under the car thats where the coolant is located). This coolant leak only recently started and isn't a very big one, it's just annoying to clean every time I park the car. Since the leak is oriented towards the back I figured the rad and all the lines that feed into the rad in the front are fine, I've checked the lines that run into the IAVC and the throttle body but nothing. Are there any other lines I can check?

 

check your thermostat to see if its leaking there, its left side of the engine at the back

 

You mean from under the intake manifold? Or rear of the engine as in transmission side?

If under the intake manifold, it could be the water pipe that goes from water pump to thermostat housing is dripping. Also there are two lines on it. One bigger hose that connects to the intake manifold and the second smaller hose that goes to iacv. I had a small leak from the iacv hose on the water pipe, it would drip right on the downpipe by o2 sensor...so it would start to smoke a bit after idling for a longer while.

It could potentially leak from intake manifold itself. Bad gasket allowing coolant to drip through the port between the head and I/M
