Cooler Flushing

Use the Kent-Moore tool J 35944-A and solvent J 35944-22 to flush the cooler. Instructions for using the cooler flushing tool and performing fluid flow check may be found in the On-Vehicle Service Section of the service manual or may be found on a Corporate Service Bulletin 77-71-59.
