The Sinister Diesel Coolant Filer Bypass system takes approximately 2 hours for installation. Installation time may vary based on experience.; Q:.Why do I need a Coolant Filtration system?, A:.From the factory, many engine blocks will have sand, from the casting process, still in the cooling channels. If not filtered out, the sand can clog EGR coolers or cause premature wear of water pumps or coolant seals. Our Sinister Diesel Coolant Filtration System is a stylish and affordable "insurance" against premature failures from debris in the coolant system.
