99.011 Need-Release for Mack Trucks


Many people are requesting information about a Need-Release filter for Mack engines. There are two Need-Release filters available for Mack engines, however, despite performing the exact same function as a regular Need-Release, they have different part numbers. The differences in the filters are strictly engineering alterations such as thread size and canister size. Detailed information on Need-Release and the Fill-For-LifeĀ® coolant program is available on Technical Bulletin 01.007.
