This Replacement Coolant Filter from CAT fits all Sinister Diesel Coolant Filtration Kits as well as all of our Bypass Oil/Coolant Filtration Kits and is available on many of them as an upgrade option.
These replacement coolant filters for diesel engines use the best quality materials to withstand whatever duty your truck sees. The advanced filtration in every CAT coolant filter removes contaminants like casting sand leftover from the manufacturing process, metal shavings, rust, and mineral deposits floating in your coolant that can diminish the heat capacity of your truck?s cooling system, lead to overheating, and even engine failure.
On new installations of a Sinister Diesel Coolant Filtration Kit, we recommend replacement of the first filter at 500 miles and replacement of the second and third filters after 3,000 miles each. After three filter changes, replacement can be done once a year.
