brian1961, asked about 03 saturn vue but fixitmr answered my question with a question how do i respond

What is your car problem?

Just to add to this one iam saturn factory trained tech of over 16yrs working for saturn dealerships.Even i would have to ask questions to help you fix your vue over the internet.Keep in mind we cant see test smell test drive etc your vechile.Even when i worked for the saturn dealers i would walk down to the service drive to talk to the customers and ask them questions about there cars.I would even call them on the phone to ask them questions even when i had the car in front of me.My point is to answer a question you need all the details etc and from all the questions you posted that i read there just not there.Also you need to stick to one question if you keep starting a new question instead of posting a reply on the same question.The person answering the question doesnt get a email alert letting them know there is a response to the question.Making it even more difficult to answer your question.You say the cooling system pressure goes up to 17psi while its running?If so was the coolant temp pretty hot?if so a lot of that pressure could be from the hot coolant expanding exporating coolant causing pressure etc.So you think you may have a blown head gasket causing exhaust pressure in the cooling system?They rent a chemical head gasket tester at the auto zone for free with deposite.You just have to buy the chemical which about 8.00.
