Hello, I would do what Spook suggested to find out if it was replaced. If you luck out do everything Ringlee said with the exception of the Volvo coolant. Do yourself a favor and your car and use the Zerex brand G-05, it does not have the solids, and has lower phosphates, which keeps your engine cleaner and cooler. Nissens make a perfect replacement for that year for 229.00. Check your local jobber.
