In my In Laws 2004 Accord 2.4L 4 cyl I want to do a coolant drain and refill before winter sets in.It is definitly GREEN in color. It has to be the ORIGINAL coolant in the car, [censored] they didn't even change the oil for almost 4 years.Anyway when I went to go get a gallon of Honda Coolant, the parts dept said it's supposed to be BLUE and has been BLUE since 1999??? Anybody have any answers on this.??
