Hey I'm new to this and I need help because my coupe has been leaking a lot of antifreeze lately especially after some fast driving. I have already put in a new water pump and thermostat and I just can't find where this leak is comming from. The antifreeze seems to be falling above the oil pan but I have not been able to locate it. Please if anybody has any suggestions it would really help me!

 

Well, the first thing you have to do is find the leak. I would start with all of the hoses. And check the oil cooler that the oil filter attaches to since there's a seal inside that can start leaking.
