I'm looking to do a coolant flush on my 03 f250 and I'm looking for some advise on what brand / type of coolant to use. It currently has the motor craft gold in it but that's pretty expensive through the dealer. Im unsure about using the universal all makes all models stuff Walmart and advance auto sell. I would most likely have to order the specific coolant I need online. So does anyone have any recommendations for me? Thanks.
