Dont think the 99 can use the long life coolant. You will need to do some searching
to find the right stuff. I believe it is low silicate, not the normal stuff.. Then you will
need to go by Ford or IH to get the coolant additive. I think it is 2-3 bottles to get
it to the right mix.

99's take green, if it is a early 99 stayt with the green and add the SCA's until you test 1800-2000 ppm, and check every 6 months or 10K. If a late 99 do a proper flush and replace with a true ELC like the Fleetrite ELC. Good for 300K with no SCA testing needed. I would also add a coolant filter as well. That orange coolant isn't the proper coolant for your truck!!
