I'm told by the dealership that an additive made by Ford should be added twice a year to the radiator, would anyone happen to know if this is true? (97 F250 127, 000)
Thanks

"Green" coolant is a low-silicate ethylene glycol based coolant that requires a cavitation inhibitor. Ford calls it FW-16, International calls it DCA 4. Both are SCAs that bond to the cast iron in the water jackets to "insulate" the cylinder wall iron to prevent cavitation. ALL diesels require an SCA to prevent cavitation. Your manual has the service intervals in the maintenance section.
A little reading about cavitation and prevention.
Mods may wanna move this out of the site comments and suggestions section.
