Product Information

Directed-Coolant Head Liner Bushings (DCHL) Part # DCHL-64-12 Carr Lane Mfg.®

These special head liners are required for Directed-Coolant Bushings, to direct coolant from a drilled manifold passage to the holes in the bushing's OD wall. Important: always order the liner length listed in the table, for proper hole alignment. DC bushings must be the same length as their liners, while DCCH bushings must extend beyond their liners to the next standard length.

Complete part numbers for all standard Directed-Coolant Liner bushings are listed in the tables below.
