84FC35 Coolant Change

[Keith Strehle]

Hey everyone, I'm slowly catching up on the maintenance items for my
FC. I don't know when the coolant was changed last. So, I have a
couple questions

Regarding the coolant...

The coolant is bright green. Does that mean it's good to go?

I plan on testing the pH. Should it be neutral? pH-7?

If the pH is good does that mean the coolant is good?

When and if I change the coolant, should I drain everything? Heaters
and all?

Okay, last one. How much coolant will I need to do the job and is
there a preferred brand or color?

Many thanks, Keith
