Oil Cooler Flow Test
- Disconnect both hoses from the oil cooler pipes. Connect the oil cooler feed pipe to the transaxle and the return pipe to the discharge hose (5). See Figure
. Clip the discharge hose (5) onto the empty oil drain container.
- Confirm the transaxle is filled with ATF. See CHECKING FLUID LEVEL & CONDITION
.
- Start the engine with the transaxle in Park range and run for 30 seconds. A minimum of 2 qts. (1.9L) must be discharged during this 30-second run time. If fluid flow is greater than 2 qts. (1.9L) in 30 seconds, go to step 4
. If fluid flow is less than 2 qts. (1.9L) in 30 seconds, perform the following diagnosis:
- Disconnect the oil cooler feed line at the radiator.
- Connect the discharge hose to the cooler feed line. Clip the discharge hose onto the empty oil drain container.
- Start the engine with the transaxle in Park and run for 30 seconds. A minimum of 2 qts. (1.9L) must discharge during the 30-second run time. Do the following according to flow rate. For insufficient feed flow, inspect the transaxle. For sufficient feed flow, inspect the cooler return pipe and the cooler.
- Remove the discharge hose, reconnect the cooler feed and return pipes to the transaxle and refill the unit to the proper fluid level. See CHECKING FLUID LEVEL & CONDITION
