2001 F250 7.3

Hey guys so I bought my truck about a year ago with a newer rad.

It appeared to be the regular green coolant so I questioned the previous owner. He assured me that it was the proper coolant for the 7.3. The previous owner did take care of this truck so I believe that whatever is in there is OK for this truck.

Here’s the problem. The truck has developed a slow coolant leak and I really need to top up the overflow bottle for now as it is too cold to do a flush and repair and refill.
Can I simply top off with Red ELC? Is there a coolant for these diesels that looks like the regular green stuff? Any ideas?

Thanks for the help

 

if its green i would use green, if its red i would use red
