WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.
- During the installation of the repaired or replacement transmission, do not connect the oil cooler pipes.
- Remove the fill cap (9) on the J 35944-A: oil cooler and line flusher and fill the flusher tank (4) with 0.6 L (20-21 oz) of J 35944-22: flushing fluid, using the measuring cup (6). Do not overfill.
- Install the fill cap (9) on the J 35944-A: oil cooler and line flusher and pressurize the flusher tank (4) to 550-700 kPa (80-100 psi), using the shop air supply at the tank air valve (2).
- With the water supply valve (1) on the J 35944-A: oil cooler and line flusher in the OFF position, connect the water supply hose from the J 35944-A: oil cooler and line flusher to the water supply at the faucet.
- Turn ON the water supply at the faucet.
CAUTION:
Do not use solutions that contain alcohol or glycol. Use of solutions that contain alcohol or glycol may damage the oil cooler line flusher, oil cooler components and/or transmission components.
NOTE:
The J 35944-22:
flushing fluid is environmentally safe, yet powerful enough to cut through transmission fluid to dislodge any contaminants from the cooler. The safety precautions on the label, regarding potential skin and eye irritations associated with prolonged exposure, are typical precautions that apply to many similar cleaning solutions. It should be noted that according to GM, use of other non-approved fluids for cooler flushing can have an adverse reaction to the seals inside the transmission.
