I have a 96 RN superjet and it currently has dual cooling but I’m switching back to single cooling as that’s how the PO had it plumbed but it’s unnecessary for my setup/water temps. Anyway i can’t find an answer about stock set up being backflushed it’s all dual cooling set ups or sj’s with a B pipe. Just looking for a clear answer as to if I can backflush stock cooling system with fully stock engine. It does have aftermarket pisser and I have a backflush adapter for my hose and it fits and will work just wondering if it can be done stock, thanks in advance!
