Cooling system maintenance
The cooling system on any diesel has special concerns. It's possible for the coolant to cavitate--produce tiny bubbles--that can with time cause pin holes throught the cylinder walls from the water jackets. For this there is an additive; Ford P/N FW-15 or FW-16, Fleetguard P/N DCA4; that needs to be maintained in the coolant. Generally this means installing 8 to 10 oz of the additive to the cooling system every 15000 miles. Another method is to monitor the cooling system with Fleetguard's DCA4 test kit P/N CC2602 or CC2602A. This measures the level of DCA4 in the system, then you add the amount of SCA/DCA as required to reach a nitrite level of 1.2-3.0 PPM. The cooling system should be drained (and flushed if you live in an area with especialy alkiline water) and refilled with a fresh 50/50 mix of coolant/distilled or demineralized water and one pint of the additive for every two gallons of coolant/water at 30,000 miles. Use only a ethylene glycol-based coolant, preferably low-silicate.

thats the additive i'm talking about! joe, i knew i wasn't the only one on here using the additive. I don't test mine (shame on me) but i do add a pint about every 15k or so.
