I know that the yellow coolant is some special FOMOCO thing. My question is, is the yellow coolant the same as the orange?? I thought that I read that it was not. I just picked up my truck from the dealer (oil change and tire rotation) and they didn't top it off. When I asked him too he wanted to put the orange in and I asked him if they were the same and he said that they were.

You CANNOT mix the red/orange stuff with the Gold

You can probably mix the Green stuff with the Gold but it is not recommended to do so for now (until Ford completes its compatability testing)

The Ford part number for the gallon jug of the Gold stuff is VC-7-A (VC-7-B in Oregon, VC-7-C for a 55 gallon drum of the stuff). I got a gallon at the local dealership for approx. $8.

Eventually, Ford is putting this stuff in all of their vehicles

Valvoline (Zerex) makes the Gold stuff for Ford

It should be available in stores in the near future

When your Ford parts dept says they never heard of such and try to sell you the green or the red/orange, refer them to the Ford Modified Vehicle Engineering Bulletin (QVM Bulletin) No. Q-79 dated February 18, 2002 and TSB 02-3-4 referenced by that bulletin.

Hope this helps.....

That is what I will probably do.

I've heard that mixing green with the new style anti-freezes is a BIG no-no. In fact, Car and Driver or Motor Trend (I get both) has a big article in this months mag about this very thing, Ken

 

I called him and he said that he would read that article and call me back. Within an hour he called back and said he read it, had a call into Ford, and to bring it in, in the morning. I am happy with that as I expected him to deny everything.

Thanks garymake for those numbers, without them I would have been SOL.
