NOTE:
Transmission fluid cooler backflushing will be carried out using the Turbo-Tank Heated Cooler Line Flusher. Follow the manufacturer's instructions included with the machine. Test the equipment to make sure that a vigorous fluid flow is present before proceeding.
- Check and top off fluid level of the Turbo-Tank Heated Cooler Line Flusher tank with transmission fluid.
- Allow the fluid in the flusher 15-30 minutes to heat up to 60°C (140°F) before using.
- Install the line adapters into the transmission cooler lines.
- Attach the flusher's red line to the transmission fluid cooler pressure line quick disconnect fitting.
- Attach the flusher's blue line to the transmission fluid cooler return line quick disconnect fitting.
- Follow the equipment instructions to purge the cooler lines and cooler prior to starting the flushing procedure.
- Allow the cooling system to backflush for 10-15 minutes, then flush the cooler in a normal flow direction for an additional 10-15 minutes.
- Clean the transaxle mounted fluid cooler tubes and the thermal bypass valve by hand.
NOTE:
The FRONT transaxle cooler line on the thermal bypass valve is the cooler pressure line.
