9. Pack adhesive into the cartridge without air pockets

to ensure continuous delivery. Put the cartridge in a

caulking gun, and run a bead of adhesive around

the edge of the rear window as shown.

NOTE: Apply the adhesive within thirty minutes

after applying the glass primer.

Make a slightly

thicker bead at

each corner.
10. Use suction cups to hold the rear window over the

opening, align it with the alignment marks made in

step 4, and set it down on the adhesive. Lightly

push on the rear window until its edges are fully

seated on the adhesive all the way around.

NOTE: Do not close or open the doors until the

adhesive is dry.

11. After the adhesive is dry, spray water over the rear

window and check for leaks. Mark leaking areas and

let the rear window dry, then seal with sealant.

NOTE: Let the vehicle stand for at least four hours

after rear window installation. If the vehicle has to

be used within the first four hours, it must be driven

slowly.

12. Connect the rear defogger sub-harness and ground

cable/antenna lead, then install the grommets.

13. Reinstall all remaining removed parts.ProCarManuals.com

System Description

Pulsed Secondary Air Injection System Description

The air pump system is designed to advance the activation of the catalyst and to reduce the hydrocarbons (HC), carbon

monoxide (CO), and oxides of nitrogen (NOx) in the exhaust gas.

The system operates after the engine starts under the following conditions:

• The engine coolant temperature is between 0°C and 70°C (32°F and 158°F).

• The difference in engine coolant temperature is more than 20°C (36°F) between the time when the engine is started and

when the engine is stopped in the previous driving cycle.

AIR CONTROL VALVE

CHECK VALVE

When the engine is started, the air pump runs and sends fresh air to the air control valve. The air control valve allows the

fresh air to flow to the exhaust ports when its diaphragm is pulled by engine vacuum. It gets engine vacuum from the air

control solenoid, which is activated by the ECM. Once the fresh air flows into the exhaust ports near the exhaust valves, it

reacts with the exhaust gases, raising exhaust gas temperatures. This promotes faster warm-up of the catalytic converter.

The system operates for a maximum of 60 seconds, but the running time shortens in relation to the engine coolant tem-

perature and the intake air temperature. When the system is not operating, the air control solenoid and the air control

valve are closed to prevent exhaust gases from entering the system.
