I have gone through a gallon of coolant in the past month. Recently, I have had to refill it everyday for the past few days. I went to one shop and they said head gasket (but is showing no other signs of head gasket issue). Went to a second shop, they said that I need a new radiator and not the head gasket at all. They said they could visibly see the leak. Went to a 3rd shop and they said nothing is wrong with my car at all. They did a pressure test and it can withstand 20psi. I called the shop back that said it needs a new radiator and they said that because it is plastic, it will only leak when the car gets heated up and that it won't leak with a pressure test. I am so confused on what to believe and want to make sure the repair i will be dumping hundreds of dollars into is ACTUALLY the issue.
