is it okay to mix the green and the blue? Does a 7 year old car need a flush or can I just add it?

 

was just gonna say the factory fill type II coolant on earlier model years was green, so if you have my01 or newer you can mix the blue and green doesn't matter both are type II.

 

so whats the advantage of flushing it versus just topping off? Car is 2002 with 30500 miles.

 

I just bought type 2 which is blue last week....they dont carry the type 1 green anymore. from what I've read green and blue are compatible only difference is blue is premixed when bought from honda.

 

mine was really dirty and it turned greenish blue so i flushed it. maybe its just a dirty blue

 

advantages of flushing?

 

I would say coolant wears out like any other fluid...idk?

 

Billman looked at my coolant and said it didn't need a flush or a change a few weeks ago... I'd assume if its the same coolant then it would be okay to just add the blue to the green and no need to flush it which seems like a hassle. Any thoughts before I do it?

 

If it's the same fluid, I see no reason to flush. The first scheduled flush it at 100K miles or so.

 

Not enough reason to change it early.
