The coolant is leaking not exactly sure what the source is. It’s somewhere by the oil cooler. There seems to have oil leak in the coolant, and coolant leak inside the oil. I’m hoping this isn’t an expensive or big fix. I’ve been observing where the leak is, and I’ve tried to flush it out but it’s clogged.

I would recommend you do a coolant pressure test. Here is a link on testing:

Once you have pressure look at the engine coolant temperature sensor and water outlet housing for leaks. See image below. #4 is the sensor and #11 is the housing and is above the oil cooler. Very common problem for these vehicles. If you see a leak I recommend you replace the outlet with a new sensor and o-ring. If you try transferring the old sensor it just ends up breaking or leaking.

Keep us posted and thank you for using 2CarPros.
