Oil Cooler Flushing & Flow Check: Notes
WARNING: This page is about a different car, the 2003 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
GM studies indicate that plugged or restricted transaxle oil coolers and pipes cause insufficient transaxle lubrication and elevated operating temperatures which can lead to premature transaxle wear-out. Many cases could have been prevented by following published procedures for transaxle oil cooler flushing and flow checking. This procedure includes flushing and flow checking the auxiliary transaxle oil cooler, if equipped. GM requires that transaxle oil cooler flushing and flow checking be performed whenever a transaxle is removed from the vehicle for service within warranty, including:
- Goodwrench SRTA.
- Major overhaul.
- Torque converter replacement.
- Oil pump replacement.
Only recommended fluid should be used when doing warranty repair on Vibe automatic transaxles. See RECOMMENDED FLUID .
