Our coolant bypass kits provide superior filtration to protect your engine's cooling system components from premature wear and failure.

CNC-Machined Billet Aluminum Construction

Each Sinister Diesel coolant filter kit features precision CNC-machined billet aluminum components designed for maximum durability and leak-free performance.

  • Aerospace-grade 6061 billet aluminum filter block
  • High-strength, abrasion-resistant silicone hoses
  • Molded silicone T-connectors for reduced failure points
  • Nickel-plated ball valves for corrosion resistance
CNC Machined Coolant Filter Components

Extended Component Life

Protects water pump bearings, EGR coolers, oil coolers, and other critical components from abrasive damage caused by contaminants.

Optimal Coolant Flow

Bypass design maintains proper coolant circulation while filtering out harmful particles that can restrict flow.

Easy Maintenance

Simple spin-on filter changes with recommended intervals to keep your cooling system clean with minimal effort.

Why You Need A Coolant Filtration

Factory cooling systems have no filtration, allowing harmful contaminants to circulate through your engine. These include:

  • Casting sand leftover from manufacturing
  • Metal shavings and rust particles
  • Mineral deposits and scale
  • Debris from component wear

Our bypass system gradually cleans the entire coolant supply while maintaining optimal flow and temperature regulation. Our system provides you the peace of mind knowing clogging and dirty coolant related issues are a thing of the past.

What's the maintenance schedule?

Replace the first filter at 500 miles, the second and third at 3,000 miles each. After the initial three changes, replace the filter annually or with each coolant flush.

Performance & Benefits

Why do I need coolant filtration?

Factory engines often contain casting sand and metal particles that can damage cooling system components. Our system removes these contaminants to prevent premature failure.
