2019 NAPA Reference Guide

NAPA Standard Service Interval (S.S.I.) Cooling System Products Spin-On Conversion Kit With our universal mounting base (Part Number 4019) you can either convert existing cartridge style coolant filters to spin-on styles or you can add the protection of a coolant filter to virtually any cooling system. The 4019 kit comes with easy to understand installation instructions. Our product line includes a variety of spin-on filters that can be used with the 4019 kit. Additive Free Type: 4069, 4070, 4083, and 4084 Additive Type: 4071, 4072, 4073, 4074, 4082, and 4088 For Mack Truck Applications NAPA part numbers 4428 (3/4-20 thread) and 4429 (1-16 thread) are used for MACK brand applications. These filters contain a supplemental chemical additive (SCA) that goes into the coolant solution and deposits a protective coating on all interior metal cooling system components while maintaining the correct pH level and helping to soften the water. These filters are compatible with glycol-based antifreezes, both normal service and extended service types that are either concentrated or pre-mixed. Part Number 4430 is the additive free version of 4428. Additive free type filters are to be used either in systems where our liquid NAPACool™ SCA is being used or where antifreeze, either new or recycled, with SCAs already in it, is being used. The additive free filters are NOT to be used either in systems using just water or just water and antifreeze. The filter eliminates harmful cooling system contamination. They must be changed in accordance with the vehicle manufacturer’s recommended maintenance schedule. 1054
