Auxiliary Oil Cooler Hoses & Pipes (La4A-El): Installation
WARNING: This page is about a different car, the 2002 Mazda 626. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The automatic transaxle oil cooler flushing must be performed whenever a transaxle is removed for service to remove existing fluid which may be contaminated and to prevent contamination of new fluid. The flushing must be performed before installation of the overhauled transaxle. Follow the instruction in the manufacturer's publication for flushing the automatic transaxle oil cooler.
- To install, reverse order of removal and tighten bolts to specification. See Figure . In order to prevent ATF leakage, replace the hose when any damage is found inside or outside of the hose, especially on areas contacting with pipes.
- Align the marks, and slide the oil hose onto the oil pipe until it is fully seated. See Fig 1 . Position the marking on the oil hose side facing up and install it. Install the hose clamp onto the hose. If reusing the hose, install a new hose clamp exactly onto the mark left by the previous hose clamp.
- Apply compressed air to the cooler-side pipe opening, and blow any remaining dust and foreign material from the cooler pipes. See Fig 2 . Compressed air should be applied for no less than one minute. Connect the negative battery cable. Inspect for oil leakage from the oil pipes and oil hoses.
- Fill the transaxle with appropriate fluid to proper level and check for correct transaxle operation. See LUBRICATION . Perform the line pressure and road tests. See PERFORMANCE TESTS in LA4A-EL DIAGNOSIS article.
