Hi everyone I have had several issues with coolant leaks since I got this car 5 years ago. I’ve replaced the water pump and the upper coolant pipe adapter(aluminum) but still a leak persists. It’s a slowish leak(refill reservoir once per month) when driving in the city, but much faster after long highway driving(lose almost 1qt in one day after letting it sit).

If anyone can shed light on where the leak may be coming from that would be very helpful. I’ll attach a few pictures from underneath, the oil pan gasket is well saturated with coolant but I hope that is just from spray. There’s a sensor I can’t seem to identify which may be an issue as well. Thanks!
