I have been reading about the green vs orange coolant and I am getting a
headache. My question here is by brother happen to due a coolant change on a
monte carlo that I sold him and he changed it from orange to green when i
went to change the coolant my self I flush it and put green also but as I was
doing that I read use the organe. My question here is should I go back to the
orange coolant. or should I stay with the green. The reason that I ask is
because on one of the forum it say that there is really no way to flush the
How long has the green coolant been in the vehicle? If it's been
in the engine for pretty much any length of time, you can flush all
the green out and use the dexcool, but the dexcool will no longer
have the extended life. So then it's a matter of deciding whether
it's worth flushing the green out, or just use green from now on
and maintain it using an older coolant flush schedule (every two
years, 40K kilometers...etc).
