I recently changed my radiator hoses in my 2002 7.3 Powerstroke. I was planning on taking a longer trip and noticed this hose was starting to degrade with surface cracks. Not wanting to take a chance I replaced it and then the top hose as well. Was thinking about using a true diesel red ELC but didn't have the time to do a complete flush. The truck had green coolant when I bought it a few years ago and I have maintained it with green and NAPA Cool. My system looked very clean from what I could see when I changed it and I don't have a coolant filter on it. I did not see any sand in the system so the previous owner must have regularly changed the coolant also.
So I refilled the system with Supertech all makes/models/colors 50/50 premix extended life coolant because its silicate free. It took 4 gallons and I added a bottle of NAPA COOL for the SCAs. After driving and circulating I tested it with strips and it showed perfect colors. Since then I did some checking to see if all makes/models extended life "green" can be used in a diesel. Well most say its not recommended.
I'm wondering why if its silicate free and if it shows good on the test strips?
Should I change out the coolant to another true green ethylene glycol coolant or do you think is this OK to run for 2 years or so?
