Fleetguard Cooling System Maintenance Products
Heavy-duty diesel engines represent an extreme environment for a cooling system to perform well and protect
the engine. In comparison to light-duty applications, cooling systems for heavy-duty applications experience
an environment which is five to ten times more severe in terms of cooling system dynamics like heat rejection,
flow rate, usage rate, and engine load factor (Table 1).
Table 1
Requirements for typical light-duty and heavy-duty engine
Heavy-duty diesel engines must run up to five times as long as a light-duty engine, and the likelihood of rebuilding is
much greater for the heavy-duty engine. With 40 percent of engine problems for heavy-duty applications being related
to the performance of the cooling system, the importance of maintaining good cooling system performance cannot
be ignored if maximum fleet reliability and reduced overall maintenance costs are to be achieved. A heavy duty
coolant must be used for a heavy-duty application in order to achieve maximum engine reliability and loweroverall operating costs.
Heavy-duty diesel engines are usually designed with wet cylinder liners that enable better heat rejection, but these liners are often sensitive to pitting from cavitation (see Figure 1). When selecting the right coolant and cooling system maintenance program, it is critical to ensure that the coolant is designed with the chemistry needed to protect against liner pitting.
Using the wrong coolant can result in expensive, premature failure of heavy-duty and some light-duty diesel engines.

Liquid Supplemental Coolant Additives (SCAs)
We recommend the use of fully formulated heavy-duty coolants. Supplemental Coolant Additives (SCA) can be used in
water-only cooling systems like marine and railroad applications. The chemistry contained in our SCA is necessary to prevent
liner pitting, corrosion, and scale build-up on your cooling system components.
