I just installed a new radiator in my Integra. I'm still losing coolant and actually almost overheated this morning coming into work. In the past week I would come out to the car and see a small puddle under my car. Other times there was nothing. I can't seem to identify where the hell it's coming from. I highly doubt it's the new radiator, and both radiator hoses are still in decent shape. I'm stumped. I'm going to check my thermostat when I get home just to make sure it's working, but even if it was stuck closed, could that cause my system to burn off coolant? Any ideas or experiences are welcome.
