I have a 1999 Durango and have problems with the fluid in the radiator disappearing. It started with the gauge going into the red zone for about 15 seconds and then going back to normal. We had a pressure test done and it was okay. Now the engine light stays on and the fluid level drops after about 150 miles. What's going on?
