7.3 Ford coolant additive
In a prior thread the number for the coolant additive was pf-22 from ford I found VC8 is this the same?

Ford did a double reversal on approving coolant chemistry change in the 2000-2001 years of the 7.3L. First Ford said no, treating the 2000 and 2001 model years just like the early 99's, which Ford has always said no about. Then, around 2004, Ford said YES, it was OK to change the Green coolant in the 2000 and 2001 model years to the Gold coolant Ford used in the 2002-2003 model years.
(To be more correct, I should say "late 99", which is also called "99.5", instead of just saying 2000. Also it is possible that some 2001s were factory filled with Gold... but I'm just roughly speaking from memory here, not attempting to be exact.)
Anyway, for about 10 years Ford approved Green and Gold coolant in 99.5 through 2003 trucks, but then Ford changed again, withdrawing their former approval of using Gold coolant in trucks that were originally filled with Green. The current Motorcraft coolant charts reflect Ford's second reversal in position, when compared to equivalent Motorcraft coolant charts from five years ago, and compared again to coolant charts from fifteen years ago.
