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.

The air conditioner system removes heat from the passenger compartment by circulating refrigerant through the system
as shown below.

When the refrigerant is below
200 kPa (2.0 kgtcm',28 Psi)or above 3,200 kPa 132 kgflcm',
455 psi), the Ay'C pressure

This car uses HFC-134a (R-134a) refrigerant which does not contain chlorofluorocarbons Pay attention to the following
service items:
. Do not mix refrigerants CFC-12 (R-12) and HFC-134a (R-134a)' They are not compatible'
. Useonlythe recommended polyalkyieneglycol (PAG) refrigerant oil designedforthe R-134a compressor (SANDEN: SP-
10; DENSO: ND_OIL8). Intermixing ihe re-commended (pAG) refrigerant oil with any other refrigerant oil will result in
compressor failure.
. All A,,ic system parts {compressor, discharge line, suction line, evaporator, condenser, receiver/dryer, expansion valve'
O-rings for joints) have to be proper for refrigerant R- 134a Do not confuse with R-l2 parts'
. Use a halogen gas leak detector designed for refrigerant R-134a
. R-12 and R-134a refrigerant servacing equipment are not interchangeable. Use only a recovery/recycling/charging station
that is u,L.-listed and is certified to meet the requirements of sAE J2210 to service R-134a air conditioning systems'
. Always recover the refrigerant R-134a with an approved recovery/recycling/charging station before disconnecting any
A,/C fitting.
