Can I use a different coolant in my Firebird?
I have a 1991 Pontiac Firebird 305
5.0L. Now I came to buy this car in
bad condition and I am slowly
rebirthing her into a performance era.
I run green coolant/antifreeze in her
system right now. HOWEVER I do
know there are other types and that I
should never mix them but I am
doing a flush soon so if anyone couls
give me insight on what different
coolants do and what they will do for
my engine in general thatd be great!
