I read in a previous post that Ford issued a service bulletin saying that the Gold extended life coolant can be used in a powerstroke engine that originally came with green coolant. If this is correct can someone tell me where to find that bulletin. I am fixing to change my coolant an would like to put the gold extended life instead of green. I have a 2001 model that came with green coolant. Thanx in advance for responses. cuttr

 

From the fiasco, I just went thru at the dealer, they changed my gold out and put green in. Anyway, after arguing with them they put the gold back in. According to Ford techs, the coolants are compatible, just don't mix them. With the gold, you won't have to mess with the FW16 additive every 15k miles.
