Fleetguard Crankcase Ventilation Filter for 6.7L Cummins - CV52001, OCV Oil Separation

Fleetguard CV52001 is a replacement crankcase ventilation filter engineered to remove oil mist and aerosols from the crankcase vent on most 6.7L Cummins engines, helping protect the engine bay and reduce oil consumption.

Keeping blow-by vapors and oil aerosol out of the intake and engine compartment extends component life and improves cleanliness. The Fleetguard CV52001 fits many 2007-and-newer Ram 2500/3500/4500/5500 trucks powered by the 6.7L Cummins and matches common OE references so you can swap it in with confidence. Its open crankcase ventilation (OCV) design balances emission control with effective oil separation to capture mist before it migrates into the turbo, intake, or electronics.

How does the Fleetguard CV52001 reduce oil consumption and contamination?

The CV52001 uses targeted media and flow channels to separate oil droplets and aerosols from crankcase gases so fewer contaminants are carried back into the intake or settle in the engine bay. That means less oil lost as vapor and fewer deposits forming on sensors and turbo components.

• OCV design captures mist and oil droplets before they escape
• Reduces oil dripping and aerosol buildup in engine compartment
• Helps maintain cleaner intake and turbo systems over time

Will this filter fit my 6.7L Cummins-powered Ram truck?

Fleetguard CV52001 is designed to be compatible with most 6.7L Cummins engines used in Ram 2500, 3500, 4500, and 5500 models from 2007 onward. It corresponds to multiple OE numbers, making it a straightforward replacement when the original part matches those references.

• Fits many 2007+ Ram 2500/3500/4500/5500 with 6.7L Cummins
• Compatible with OE numbers CV52001, 4936636, and 68002433AB
• Direct-swap design simplifies installation and service intervals

How do I install or service the CV52001 crankcase filter?

Installation is generally simple: remove the old crankcase vent assembly or element and replace it with the Fleetguard unit following vehicle manufacturer guidance. Always shut down the engine, let it cool, and follow torque or sealing instructions from the vehicle manual to avoid leaks.

• Shut off engine and allow cooling before service
• Remove existing vent/filter and replace with CV52001 element
• Check seals and hose connections for tight fit and proper routing

How often should the crankcase filter be replaced?

Replacement intervals vary with driving conditions, engine hours, and maintenance schedules from the vehicle maker, but regular inspection during routine service helps spot saturation or oil carryover early. Replace the filter if you notice increased oil vapor, oil leaks, or excessive contamination on surrounding components.

• Inspect at regular oil change intervals or by vehicle schedule
• Replace if oil mist, dripping, or clogged media is observed
• Frequent heavy towing or dusty operation may require earlier changes

Who is this for: The Fleetguard CV52001 is aimed at owners and technicians of Ram trucks with the 6.7L Cummins who need a reliable replacement crankcase ventilation filter that matches common OE references. If you service 2007-and-later Cummins engines, perform preventative maintenance, or want to reduce oil carryover and keep intake and engine bays cleaner, this CV52001 unit is designed to meet those needs with an OE-compatible fit and OCV performance.
