I have a 2000 Chrysler Cirrus and I recently started the car and I had an oil like substance leaking from my coolant system. It looked like the engine oil for my car mixed with the coolant that was in my car and it was coming out of the resevoir and when i took the radiator cap off it was coming from there as well. Would you be able to help me find out what is causing this problem?
