Chevrolet Cobalt Service & Repair Manual: Transmission Oil Cooler Line, Flush
| Warning: Wear eye protection.
Wear standard industrial rubber gloves. |
| Warning: Keep lit cigarettes,
sparks, flames, and other ignition sources away from the area to prevent
the ignition of combustible liquids and gases. Keep a "Class B" fire
extinguisher in the area where the flusher will be used. |
| Warning: Keep the area well
ventilated. Do not let flushing solvent come in contact with your eyes or
skin: If eye contamination occurs, flush eyes with water for 15 to 20 seconds.
Remove contaminated clothing and wash affected skin with soap and water.
Seek medical attention. |
| Caution: Do not use solvents
containing acids, water, gasoline, or any other corrosive liquids. |
| There are two different procedures
for flushing coolers and lines. The recommended procedure is to use a cooler
flush machine. |
Cooler Flushing Machine
| Transmission oil cooler line flushing
procedure may vary slightly depending on equipment manufacture. Follow instructions
and procedures as provided by the equipment manufacture. |
| 1. |
Fill reservoir of flush machine with
fresh flushing solution. Flushing solvents are generally petroleum
based solutions used to clean automatic transmission components. |
| 2. |
Verify pump power switch is turned
"OFF." |
| 3. |
Connect pressure line to outlet from
cooler line. |
| 4. |
Connect return line to inlet to cooler
line. |
| 5. |
Turn pump on for two to three minutes
to flush cooler and lines. |
| 7. |
Disconnect suction line from machine
reservoir. Disconnect return line and place it in a drain pan. |
| 8. |
Turn pump "ON" for 30 seconds to purge
flushing solution from cooler and lines. Turn pump "OFF." |
| 9. |
Place suction line into a one quart
container of clean transmission fluid. |
| 10. |
Turn pump "ON" until all transmission
fluid is removed from one quart container and lines. This purges
any residual cleaning solvent from transmission cooler and lines.
Turn pump "OFF." |
| 11. |
Remove flushing adapters from cooler
lines. |
|
Manual Flush
| 1. |
Disconnect cooler lines at transmission. |
| 2. |
Reverse flush cooler using a hand suction
gun filled with mineral spirits. Force mineral spirits into line
from cooler and catch exiting spirits from to cooler line. Observe
for presence of debris in exiting fluid. Continue until fluid exiting
is clear and free from debris. |
| 3. |
Blow any remaining mineral spirits
from cooler, again in reverse direction using compressed air under
40 psi in intermittent spurts. |
| 4. |
Pump one quart of automatic transmission
fluid through cooler before connecting. |
| 5. |
If at any stage of cleaning process,
cooler does not freely pass fluid, cooler must be replaced. |
