Sinister Diesel Universal Coolant Filtration System

The Sinister Diesel Universal Coolant Filter Kit is designed to extend the service life of your Duramax, Powerstroke, or Cummins-powered diesel truck by removing dangerous contaminants and deposits from inside the engine's cooling system. Particles like casting sand, metal shavings, rust, and mineral deposits contaminate your coolant and can result in reduced heat capacity, overheating, breakdowns, and damage to water pump bearings and EGR cooler passages. This kit ensures your cooling system works at maximum efficiency. It includes all mounts and fittings needed for installation and is machined from 6061 billet aluminum. The filter boss has 2 threaded inlet ports and 1 outlet port. Recommended filter replacement is at 500 miles for the first filter, then after 3,000 miles for the second and third filters. After three filter changes, replacement can be done once a year.
