I can't help you with the proper coolant type, but you should be aware
that the system will hold likely 40% of it's volume inside the heater
core and engine block.

This means you will 'already' have a 40% water mix in there when you
start filling it with 'pure' antifreeze.

I always find out what the capacity is from the owners manual and add
half that in pure antifreeze if I want a 50/50 mix. I then top it up
with water. I actually have had 50/50 freeze up here in Ontario Canada
so I prefer 60/40.

Canadian Tire still sells 'green' antifreeze but be careful what you
buy. They now sell it premixed which is 'only' good for topping up, not
filling after a flush. And they charge more for the distilled water in
the premix, then pure antifreeze!

I've been using Sierra in my '93 with no problems. No overheating, no
freezing and no corrosion. Way too many animals and children where I
live to risk using EG when I have a choice. I've seen EG poisoning and
I hope never to again. My 2 cents.
