I have a 2004 Volvo 5.0 OSI-EF fresh water cooled I want to drain and add new coolant. No problems just maintenance. Does it matter what brand I use or could I just go to my local Napa?

Make sure if you have green, you use green, if you have orange, you use orange. They do not mix

However you should have orange (dexcool)

Hi
traditionally VP antifreeze FW coolant is green as far as I’m aware.
Although guilty of using any old af in my raw water cooled engine over winter...there apparently is marine friendly antifreeze available. As in harmless to the marine life etc etc blah blah. Haha.

Depends on vintage of motor, however the OPs should have been dexcool
