How much SCA / DCA4 on a fresh flush and fill

[rkpatt]

The coolant in my truck is now a little beyond the recommended 2 year life of SCA (currently Napacool ) so I need to plush the system and refill with new antifreeze ( 50/50) and SCA . Last time I used Napakool SCA but I may use Fleetguard DCA4 for genosgarage.com this time . How mucn SCA do I add on the initial fill before I test ( I vaguely remember 2 pints but am not sure ) ? - Thanks

From the diesel suppliment/7.3liter IDI. Add 2 pints of coolant additive (cooling system capacity 29 -31qts)

You can get DCA4 at any IH dealer near you.....they have test strips required too...

CC2602B- Contains one single pack (comes in box of 100 "strips usually sold individually at the counter")

Thanks guys. I will get the Napa Kool (and test strips) if the nearby NAPA store has it on the shelf or order the Fleetguard DCA4 (and strips) from Genosgarage.com . The location of IH dealer is too inconvenient for me .
