Iam just wondering why do some 03's have Extended life coolant (yellow), and others have the regular coolant(green)? I have the regular

Ford is phasing it in and likely doing some field engineering studies - it also probably has tons of the old Green it needs to use up. The Yellow is the way to go - I posted on why last week.

I'm glad mine has the green coolant. I don't want to be the guinea pig for Ford.

The Yellow Coolant has been proven in Europe, where aluminum engines and high demand applications exist, and in much more expensive engines. It has proven to be better at corrosion protection, reduction in abrasion to water pump impellers, gaskets, etc. Trust me, it is outstanding, and the better of the Green stuff by a country mile. Had my car not come with it, I would have switched over to one of the similar compounds from either Europe or Japan (Honda's Type 2, or Audi's, which is the same G-5 as Ford's Yellow).
