Why Do Commercial Vehicles Need Coolant Filters
2025-10-11
Commercial vehicles are built for endurance, but their cooling systems face constant attack. Contaminants like scale, debris, and solder balls cause abrasion, while electrochemical reactions lead to corrosive pitting, especially on cylinder liners. A Coolant Filter is not an optional extra; it is a core component for reliability and total cost of ownership.
How a GREEN-FOLTER Coolant Filter Provides Multi-Stage Protection
A GREEN-FILTER unit is an integrated protection system. It works by:
-
Chemical Scavenging: The filter media is pre-charged with Supplemental Coolant Additives (SCAs) that are slowly released to neutralize acids and replenish corrosion inhibitors.
-
Particulate Capture: High-capacity media traps abrasive solids, preventing wear on the water pump and seals.
-
Cavitation Defense: Maintains the correct SCA level to protect liner surfaces from destructive implosions.

Your Coolant Filter Questions Answered
How often should a coolant filter be replaced on a commercial truck
Replacement intervals vary by engine model and operation. A general guideline is every 500 engine hours or 25,000 miles. For precise timing, we recommend testing coolant SCA levels with a test kit at each service interval.
Can I retrofit a coolant filter to an older fleet vehicle
Yes. GREEN-FILTER offers universal retrofit kits that include the filter head, bracket, and hardware. Installation is straightforward and is one of the most cost-effective upgrades for extending engine life.
What is the primary financial benefit for a fleet manager
The primary benefit is drastically reduced downtime and repair costs. Preventing just one major failure, like a cavitated engine block or a seized water pump, can pay for a fleet's entire Coolant Filter program for years.
Protecting your assets is a business decision. Choosing GREEN-FILTER is choosing proven technology to maximize uptime and minimize repair bills.
