If its totally empty, then off. Other than that it doesn't matter.

EDIT: :think: Wait aminute, the new ones have only one cap... that means teh whole system should be under pressure with a hot engine. So, if the engines hot, wait till it cools off to add. Once the cap is open though, it shouldn't matter if its running or not.

if its off though how high do you know how to fill it, since the fluids can expand when the engine is hot and go past the "full" mark if you fill it up to that level when cold? BTW< I am referring to the coolant resevoir tank

Also, is it okay to mix the new coolant with the existing one for the time being? (no time for flush)?

Yeah, no problem mixing coolant, as long as you don't mix green with orange its just fine. Don't even worry about flushing it.


Hmm thats odd..

I say drain the rad then refill it a few times lol

If you have a NBS, take the upper rad hose and add coolant to it to fill up the rad quicker. Makes it much quicker to fill the system up.

Once the rad is full, fill up that overflow box and ya should be mkay. That's what I did when I changed my thermostat.
