Ok...same 99 Gmc Savanna 5.7l as usual...now I just finished changing the
intake manifold gaskets, and I figure I'll scab up enough tonight to
undertake the coolant flushing tomorrow...Question is a friend suggested
vinegar as a flushing agent...Any pro's or cons will be appreciated...I
just planned on filling with water getting to temp...draining a few
times...thanks in advance ...
