My car is leaking coolant, but I can't find where. Yesterday the temperature was probably 0 degrees and she hesitated to start but after warming up for 5-10 minutes the coolant light started flashing and I checked and refilled the reservoir then today the same problem happened. Not sure where the coolant is going, I can't see any wet/coolant on anything under the engine.

I heard about possibly being the coolant flange at the back of the engine, but it looks like old oil around it, not actually coolant?

What should I do? replace the flange at the back of the head and hope for the best? how hard is the replacement?
