Hello. I have a 07 Sedan with about 85,000 miles on it. I've had the car for about a year, and I slowly noticed that the coolant seemed to be leaking out. In the winter, it would effect the heat, and this summer in hot temps, it would need to be filled up frequently. Then, the other night I was driving home and it overheated and decreased in speed. Next, the oil went from 55% to 0%.
I have put in a sealant in both the oil and the radiator, and am going to get an oil change and flush the coolant...but will that do it, or do I have a blown gasket? (huge fear) This is my first car, and I'm learning as I go. I don't want to destroy the engine. I haven't driven it except to run the engine to get the sealants through. Any thoughts?
