My question was poorly written. What I was hoping to find out is whether any harm would come from putting Zerex G 05 in a system that has had a less-than-perfect flush after draining conventional green antifreeze.
I also have the same question about the Mercedes coolant. If I change from conventional green stuff to the MB coolant, how important is it that I get every last bit of the green stuff out of the system before installing the MB coolant.
I hate messing with antifreeze.
