OIL COOLER FLUSHING [FN4A-EL]
| WARNING | A hot transaxle and ATF can cause severe burns. Turn off the engine and wait until they are cool before changing the ATF. Using compressed air can cause dirt and other particles to fly out, causing injury to the eyes. Wear protective eyeglasses whenever using compressed air. |
Note. If the transaxle is replaced, flush and inspect the oil cooler. When replacing the transaxle, inspect the oil cooler together with flushing it using the following procedures, and with the oil hose removed.
Scheme 422
Scheme 423
- Disconnect the oil cooler hose from the transaxle. (See «OIL COOLER REMOVAL/INSTALLATION [FN4A-EL]»(ref-517464-S01561269972012121200000).)
- Set a clean oil pan up to the oil cooler hose inlet (Scheme 422): Blowing Compressed Air Into Oil Cooler To Drain Oil
- Blow 491-882 kPa {5.01-8.99 kgf/cm 2, 71.3-127.0 psi} of compressed air into the oil cooler hose outlet to drain remaining oil. (Scheme 423): Blowing Compressed Air Into Oil Cooler Hose Outlet To Drain Remaining Oil
- Add new ATF from the oil cooler hose outlet and blow 491-882 kPa {5.01-8.99 kgf/cm 2, 71.3-127.0 psi} of compressed air to flush. (Repeat 2 or 3 times)
- Verify that none of the following foreign material is mixed in with the drained ATF: Large metal fragments of 0.5 mm {0.02 in} or more that cannot pass through the oil strainer Fibrous clutch facing
- Repeat the procedures from Step 4 and flush the inside of the oil cooler. If foreign material such as metal fragments or clutch facing remains even after the oil cooler is flushed repeatedly, replace the oil cooler. (See «OIL COOLER REMOVAL/INSTALLATION [FN4A-EL]»(ref-517464-S01561269972012121200000).)
On-Vehicle Removal
| WARNING | Using compressed air can cause dirt and other particles to fly out, causing injury to the eyes. Wear protective eyeglasses whenever using compressed air. A hot transaxle and ATF can cause severe burns. Turn off the engine and wait until they are cool. |
| CAUTION | Water or foreign objects entering the connector can cause a poor connection or corrosion. Be sure not to drop water or foreign objects on the connector when disconnecting it. |
