....and every fluid in the truck was still factory fluid
, not to mention that the orange/yellow coolant was in my reservoir when the diagram clearly illustrates to use green only. No problem, had every fuid flushed out and refilled, and truck is in great mechanical shape!
Gas mileage definitely not what I expected. My G8 gets way better gas mileage.
I did notice that the coolant reservoir doesn't seem to be at the cold fill level. I went to a nearby dealrship and bought the Motorcraft green coolant which was not pre-mixed. I told the parts guy that all I need to do is just add a little to the reservoir, and he said it is ok to add just the coolant (no water) to get it up to the cold fill level. I don't know, but I am hesitant to do that. Would it really cause any problems?
