24. Installthe intake air duct.
D16Y7 engine:
Install the intake air duct and the resonaror.
D16Y8 engine:
lnstall the intake air duct and the air cleaner hous_ang assembly.
25. Refill the transmission with ATF (see page 14_1.18).
26. Connect the positive (+) cable first. then the nega-tive (-) cable to the battery.
27. Check the ignition timing (see section 23).
28. Start the engine. Set the parking brake, and shift thetransmission through all gears. three times. Checkthe shift cable adjustment (see page 14_190).
29, Check the front wheel alignment (see section 1g).
30. Let the engine reach operating temperature (thecooling fan comes on) with the transmission in Nor @ position, then turn it off and check the fluidlevel (see page 14- 7).
31. Road test as described on pages 14-113 thru ,14_116.
