Engine Coolant Filters

Your Engine's cooling system coolant filters are installed to remove containment from the engine's cooling system. The coolant filter is also used to maintain the cooling system's proper operation and PH balance. Coolant filters are designed for use in both gasoline and Diesel engines. A majority of your engine downtime is due to coolant system-related failures. With today's diesel engines, coolant balance is key to keeping your engine running efficiently for long-term operation with efficiency.

The function of the coolant system and the Engine Coolant Filter is to:

  • Remove heat from the engine components
  • Circulate clean coolant in the engine coolant passageways
  • Dissipate the captured heat through the radiator
  • Control coolant temperatures under all operation conditions

Your engine's coolant and filter regularly battle the formation of these suspended particles and cooling system conditions:

  • Rust,
  • Scale
  • Acidity
  • Debris
  • Silicate Drop Out
  • Damaging Temperature Extremes

What types of engine coolant filters are there?

There are several types of engine coolant filters available, and each of these coolant filters is designed to meet different engine coolant system requirements and maintenance practices.

PRE-CHARGE COOLANT FILTERS: These contain enough coolant additives to charge the cooling system initially and to allow for depletion to the first service interval.

STANDARD CHARGE COOLANT FILTERS: This type of coolant filter contains a chemical additive that maintains the engine coolant system protection level during a predetermined maintenance period.

NON-ADDITIVE COOLANT FILTERS: This type of engine coolant system filter does not contain chemical additives and can be used with cooling systems maintained by liquid additive, systems using long-life coolants that require no additive, or on overcharged systems to bring the additive level back to normal range.

COOLANT FILTERS WITH ADDITIVES: Fleetguard filters with engine coolant additives contain small amounts of time-released additives to replenish coolant and maintain healthy coolant conditions. They can also be used as a direct replacement for standard filters..

It’s important to choose the right type of coolant filter based on your vehicle’s requirements and the coolant system’s specifications. Always consult your vehicle’s owner’s manual or a professional mechanic to ensure you select the appropriate filter for your engine.

KLM performance offers these Spin-on filters in a variety of types and efficiency ratings to meet your maintenance needs and practices. These Fleetguard Filters from Cummins Filtration help keep hot-running engines cool and reduce downtime. See these Replacement Coolant Filters for the proper protection of your engine's cooling system. A diesel engine depends on its cooling filtration system for protection from damaging temperature extremes. The replacement of your engine cooling system filter plays a vital part in the long-term operation of your engine with reduced downtime.

Why do you need to change the engine's Coolant Filter? 

As a direct result of the engine manufacturing process, there is debris in the coolant system.  Over time, other debris, such as silt and dirt from the environment, or poor maintenance practices, such as refilling with dirty water or the use of dirty containers, enters the coolant system. This dirt and silt cause significant abrasive wear throughout the coolant system. Debris and particulate matter also become more prevalent as the engines are used under normal operating conditions.  This is why changing your engine's coolant and filter is vital to a long, trouble-free operation of the engine.

KLM Performance recommends that you reference your engine's service manual for the complete list of cooling system maintenance requirements.
