New Water Lines Groups are Used for Venting of the Separate Circuit Aftercooler {1380}

Usage:

Engine: 3508B (S/N: CNB1-UP; 1TW1-UP) 3512B (S/N: CMC1-UP; BLF1-UP; 8RM1-UP; 6WN1-UP; 4AW1-UP) 3516B (S/N: FDN1-UP; 6HN1-UP; 7RN1-UP; 9AN1-UP)

Description of Change: New water lines groups provide venting of the aftercooler system on gensets that have a CVS radiator. This is needed so that the jacket water coolant and the aftercooler coolant do not mix.

Adaptable To: The new water lines groups are adaptable to all of the 3500 Engines that are listed above. Table 1 lists the effectivity of the new water lines groups for 3500 Engines. Table 2 lists the radiators, the radiator groups, and the water lines groups that are used for 3500 Engines with CVS radiators.
