To make it simple I wanted to put in John Deere Cool Guard II antifreeze. I assume this is okay in the New Holland? Anyone else use this in there non Deere equipment?? [Reply]   [No Email]

The more modern diesels were more prone as the engine designs became more efficient... hensce the 10 series and newer were more susceptable.   [Reply]  [No Email]

Follow Jerry's advise.   [Reply]  [No Email]

If this is not done, the walls of the cylinder will develop pinholes. Ford had problems (as did other companies) when the higher horsepower diesels came out in the 70's and 80's. Most larger tractors now have a coolant filter on them that supplies the needed stuff. I believe that the PH and chemicals in the water used also was a factor. Thus certain areas of the country had more problems than others. Fordfarmer knows of this problem. A bottle of FW-15 can be found on the shelves of CNH dealers. I paid 7.03 for it a month ago.

Borrowed this from another forum, Rick, I saw you in there I think. "The terminology of SCA is Supplemental Coolant Additive. Since one company, Fleetguard, makes these coolant additives under the trade name of DCA4 or DCA2, the generic term has become DCA. What these chemicals do in your engine cooling system is to provide protection against cylinder wall cavitation pitting failures. When a diesel engine runs it produces cylinder wall vibrations from combustion and piston slap. These vibrations produce minute movement of the cylinder wall that cause vacuum bubbles to form in the coolant. These bubbles implode (like explode but inward, not outward) against the cylinder wall surface with forces measured at 20,000 PSI. Sufficient force to break out tiny pieces of the cast iron eventually leading to coolant getting into the oil through a perforation. Engine rebuild is the only option then. Use of SCA or DCA creates a tough oxide film on the surface of the cylinder wall (coolant side). The testing of the dissolved SCA level is an indirect means of determining the level of cavitation resistance your coolant has. Even with these additives, the phenomenon of cavitation is taking place. The difference is the hard oxide coating that takes the "blast" of implosion. If you test the coolant and find the SCA level decreasing, you have a strong indication that the cavitation phenomenon is active in your engine. If your Cummins is a B5.9L or QSB (24 valve with Electronic Control Module, ECM) you have no reason for concern regarding cavitation damage. As an employee of Cummins, I work with Mid Range Service (B, C, & L). Only the B engines are immune. C and ISL engines do have cavitation and must have coolants that contain SCA and also require periodic replacement of the coolant filter or use of a liquid SCA additive."   [Reply]  [No Email]

If you buy a diesel rated antifreeze, it"s all ready in there. Your call on the brand.   [Reply]  [No Email]
