My ranger and mustang both have this coolant and require it to be changed every 100K or 5 years and use this coolant only. Any of you know where I can get this for a decent price? I found it for $20 per gallon somewhere but thats just insane. Can't find it anywhere else. I don't want to go to the dealer for it.

 

So nobody here has changed their coolant and used this stuff?

 

NAPA stores have it. Maybe Car Quest too.

You need a Ford approved G-05 coolant. Stay away from the universal (AKA Dexcool w/o the Dexcool name) crap. NAPA stores usually carry Zerex G-05, but you will have a hard time finding it anywhere else.

Zerex is usually $15/gal or so. Motorcraft is usually around $17/gal, but it depends on the dealer.
