Had to put new thermostat and coolant temperature sensor in the 99 Volvo S70. When I drained the G-05 that had been in the system for a couple of years I was surprised at how nice and clean it was. No cloudiness at all with a nice yellowish tint. BTW, the new coolant sensor solved a variety of issues with the Volvo, including rough running and hard to start after a short cool-down. Running like a champ again at 235k.
