Thread: Coolant or antifreeze? Sbc

    Coolant or antifreeze? Sbc

    Can anyone recommended a coolant or antifreeze for sbc. I believe that it had antifreeze in it before but was very brown and was hoping that I could stop this happening again now I've flushed it all and fitting a new aluminium radiator.
    thanks

    Use blue ( top grade ) or Green ( shorter usable life span ) , Red is for modern engines and isn't kind to brass etc used in waterpumps etc in older engines.

    Max of 50% mix as this will give greatest cooling.

    Yep I use the comma blue stuff and as you say you need to flush the Brown crap out first.

    The red stuff is very acidic apparently, has OAT in it which is the bad stuff for older engines which have brass etc in them!!
