Green, Yellow, Orange, Red, or Blue Antifreeze?

Read the specifications on the anti freeze container. If it meets the standards set by Ford, it is safe to use. My guess is it will. Why would a manufacturer formulate a product for only half or less of the market?

When I worked for Oldsmobile, their's was purple.

If a 50/50 mix of water and antifreeze will protect down to -34 it should be fine.

Like bob c said.

Oh, and, change it every 5 years.

I have worked in the automotive field for 15 yrs. As far as I know you are not supposed to put green in any car with any other color antifreeze or else it will "gel up". There is a type of antifreeze that is called "all makes all models" avalaible almost everywhere af is sold it only cost a few dollars more and will work in "all makes and models" and last longer than the green.

Mixing Dissimilar Coolant Technologies

Mixing antifreeze grades can be rather dangerous. The technology has changed much in the last few years. Conventional anticorrosive packages have in many cases been replaced with what is called Organic Acid Technology (OATS for short). Some manufacturers do not like silicate technology anymore and mixing their stuff in with your stuff may cause a precipitate to form that is rather like sand. Also, foreign cars may use even different color schemes. Going by color is NOT safe anymore. I think I would confine myself to being very careful to read the label and even consider getting antifreeze from the Dealer.

Read the specifications on the anti freeze container. If it meets the standards set by Ford, it is safe to use.

I drive a Jeep Grand Cherokee and recently had radiator and hose problems. The antifreeze that was in there was pink (red) as per manufacturer recommendation. The mechanic told me not to use the red stuff because it wears out the seals and tubing in the radiator system faster than green. They totally flushed the system and replaced it with green antifreeze on top of some other radiator work. I would still probably go with the manufacturer's suggestions anyway unless the work was guaranteed.

Thanks for you comments and information. I think I already put in a little of the green before I knew it was yellow, but I won't mix it anymore. That may be why I got a leak. BTW, my son had a coolant leak and using 3 of the expensive stop leaks didn't work so he used black pepper and it worked.

If you ever took apart an engine after stop leak had been used in it you would never ever use that product. It may stop your leak but it also stops, clogs many other parts of the engine that you would not have intended it to. Nasty, nasty stuff! May cause damage than good. Would recommend fixing coolant leak properly.

Never put that crap in your engine. Imagine black pepper having same effect.

The experts a Ford (fleet maintenance operations in this case) say, "Definitely do not substitute or mix in anything but the original (gold) type coolant installed in your Taurus...or regrettable consequences will result. The same holds for other "colors" recommended and used in automobiles (to the extent which the manufacturers do not state which, if any, other colors can be used).

Yes this can be an inconvenience and an additional expense but, (in the case of the Taurus) the gold (or other color depending on model year) antifreeze is good for a very long time (100k as I recall)...so the cooling system needs no service and no coolant replacement (except replenishment topping off if needed).

The criticality of following mfr recommended use of "original color" involves the chemical makeup in terms of preservation (read coolant life) and corrosion protection. Substituting other color will damage the protection orginally installed in the engine.

Again, this answer came from the manufacturer of your Taurus.
