Overview of Fleetguard WF2165 DCA-Release Spin-On Coolant Filter
The Fleetguard WF2165 is a spin-on coolant filter with DCA (Diesel Coolant Additive) release. It features dual functions: physical filtration and chemical protection. Moreover, it is designed for heavy-duty engine cooling systems like Cummins. It is an ideal choice for Cummins QSX 15 TIER III/IV engines and other heavy-duty models. It ensures optimal performance and long-term protection of the engine cooling system.
Core Structure of Fleetguard Coolant Filter
First of all, let’s focus on its core structure. It has a metal spin-on housing with M36X2 threads. This allows for quick and convenient installation. Besides, the filter layer is made of deep filter paper or composite fiber. It mainly intercepts solid impurities in the coolant. Additionally, the DCA release layer—with built-in solid additive particles—is the core functional layer. Furthermore, the flow guide and support structure ensures even coolant flow. It also prevents short-circuiting, maximizing the filter’s effectiveness.
Physical Filtration Principle
Its working principle has two core processes: physical filtration and chemical protection. On one hand, its physical filtration (mechanical purification) works simply. Coolant flows into the housing inlet. It passes through the filter from inside out and returns to the cooling system via the central tube. During this process, its 10–25μm micro-pore filter paper intercepts rust, scale, sand and metal debris directly. At the same time, the fiber medium absorbs tiny suspended impurities and colloids. This keeps the coolant clean and prevents blockages, pump/radiator wear, and reduced heat dissipation.
Chemical Protection via DCA Release in WF2165
On the other hand, chemical protection comes from its DCA release function. When coolant flows through the release layer, the solid additive dissolves slowly and evenly. It supplements the coolant with anti-corrosion, anti-cavitation and anti-scale agents. Specifically, these additives form a dense protective film on metal surfaces. This inhibits electrochemical corrosion and prevents cavitation damage from coolant bubble rupture. In addition, they chelate calcium and magnesium ions to avoid scale. They also maintain heat dissipation, stabilize coolant pH, neutralize acids, and extend coolant life.
Complete Working Process
Its complete working process is simple and efficient. When the engine runs, coolant circulates into the filter. It first filters impurities, then dissolves the additive. The clean, additive-rich coolant returns to the system to protect the engine. As the filter is used, its element becomes impurity-saturated. The additive is also exhausted, so regular replacement is needed. This is usually every 500–1000 hours or per the maintenance manual.
Difference Between WF2165 and Ordinary Water Filters
Compared with ordinary water filters, this Fleetguard filter has obvious advantages. Ordinary water filters only provide physical filtration. They have no chemical protection. In contrast, this WF2165 integrates filtration and DCA release. This makes it both a “purifier” and a “protector station” for the cooling system. This is its key advantage over ordinary filters.
Detailed Specifications of Fleetguard WF2165 Coolant Filter
Next, let’s introduce its detailed specifications. Its D1 and D2 are both 93.000mm, while D3 is 0.000mm. The thread specification (D7) is M36X2, H1 is 147.000mm, weight is 0.690kg, and volume is 0.001308 m³. These specifications ensure compatibility with the installation space and working requirements of various heavy-duty engines.
