Cooler Flushing and Flow Test
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2008 Suzuki Reno, 2008 Suzuki Forenza, 2007 Suzuki Reno, 2007 Suzuki Forenza, and 2006 Suzuki Reno. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
You must flush the cooler whenever you receive a transaxle for service. Cooler flushing is essential for SRTA installation, major overhaul, whenever you replace a pump or torque converter, or whenever you suspect that the fluid has been contaminated.
After filling the transaxle with fluid, start the engine and run for 30 seconds. This will remove any residual moisture from the oil cooler. Disconnect the return line at the transaxle and observe the flow with the engine running. If the fluid flow is insufficient, check the fluid flow by disconnecting the feed line at the cooler. Observe the flow with the engine running.
- If the flow from the cooler return line at the transaxle is insufficient, check the flow rate from the feed line to the cooler. Blockage exists in the transaxle or the cooler.
- If the flow from the transaxle feed line to the cooler is insufficient, the transaxle is the cause of the fluid flow problem.
- If the flow the transaxle feed line to the cooler is insufficient, but flow from the cooler return line to the transaxle is insufficient, inspect the cooler pipes and fittings. Then repeat the cooler flushing procedure. If the flow is still insufficient, replace the cooler.
