Lacienega Posted November 18, 2021 Report Share Posted November 18, 2021 I was looking for some more motorcraft orange prediluted antifreeze that I've bought 2 years ago (# VC3DILB (3DIL) ), but apparently Ford doesn't sell it anymore. Instead they have the Yellow Prediluted Antifreeze now only. Did Ford update and recommend the yellow stuff now? Would it be OK to mix the orange with the yellow one? Or should I flush it first??

homestead Posted November 18, 2021 Report Share Posted November 18, 2021 (edited) Looks like it is ok to use... https://www.fcsdchemicalsandlubricants.com/quickref/FCSD Motorcraft Yellow Antifreeze-Coolant Backward Compatability.pdf • Motorcraft® Yellow Antifreeze/Coolant can be used to top-off or entirely replace (drain and refill) antifreeze/coolant in vehicles factory-filled with Motorcraft® Orange Antifreeze/Coolant and Motorcraft® Specialty Green Engine Coolant. Flushing: • Flushing the cooling system is not required prior to entirely replacing (draining and refilling) Motorcraft® Orange Antifreeze/Coolant or Motorcraft® Specialty Green Engine Coolant with Bittering Agent with Motorcraft® Yellow Antifreeze/Coolant if the cooling system is not contaminated.

jzchen Posted November 18, 2021 Report Share Posted November 18, 2021 I Googled the 2013 Ford C-MAX ENERGI owner's manual and opened it. The specification listed there is WSS-M97B44-D2 and as kindly shared by @homestead it is a compatible replacement. Quote Link to comment Share on other sites More sharing options...
