INSPECTION — CALIFORNIA MODELS

System Inspection

NOTE: A vacuum pump capable of producing more than 10 in. Hg (33.8 kPa) of vacuum will be needed to perform this test.

ALTITUDES BELOW 3,900 FT. (1,200M)

When disconnecting the vacuum hose, put a mark on the hose so that it may be reconnected to the original position. The engine coolant temperature should be 185–205°F (85–95°C).

1. Connect a timing light to the engine.
2. Remove the air filter.
3. Disconnect the vacuum hose (black) from the carburetor primary emulsion well bleed nipple and plug the nipple.
4. Connect a hand vacuum pump to the vacuum hose and check to see that the vacuum does NOT leak, while running the engine at idle.
5. Connect the vacuum hose back to its original position.
6. Run the engine at idle and check ignition timing. The timing should be 6–10°BTDC for the 2.0L engines and 5–9°BTDC for the 2.6L engines.
7. While the engine is idling, disconnect the vacuum hose (yellow stripe) from the HAC and put a finger at the hose end to check that vacuum is felt.
8. Connect everything back to its original position and remove the timing light.

4. Connect a hand vacuum pump to the vacuum hose and check that the vacuum leaks, while running the engine at idle.
5. Connect the vacuum hoses back to their original positions.
6. Run the engine at idle and check ignition timing. The timing should be 13°BTDC for the 2.0L engines and 12°BTDC for the 2.6L engines.
7. Connect everything back to its original position and remove the timing light.

High Altitude Compensator (HAC)

NOTE: A vacuum pump capable of producing more than 10 in. Hg (33.8 kPa) of vacuum will be needed to perform this test.

ALTITUDES BELOW 3,900 FT. (1,200M)

1. Disconnect the vacuum hose (white stripe, two nipples side) from the HAC and connect a hand vacuum pump to the HAC nipple.
2. Apply vacuum and check that it leaks and does not hold steady.
3. Disconnect the hand pump and plug the vacuum hose back onto its nipple.
4. Disconnect the vacuum hose (black) from the HAC and connect a hand vacuum pump to the HAC nipple.
5. Check to see that the vacuum holds steady.

ALTITUDES ABOVE 3,900 FT. (1,200M)

1. Disconnect the vacuum hose (white stripe, two nipples side) from the HAC and connect a hand vacuum pump to the HAC nipple.
2. Apply vacuum and check that it holds steady.
3. Disconnect the vacuum hose (black) from the HAC and connect a second hand vacuum pump to the HAC nipple.
4. Check to see that the vacuum leaks or does not hold steady.
5. Reconnect the vacuum lines to the HAC.

Vacuum Switching Valve (VSV)

These procedures are the same as the non-California procedures described earlier.

Check Valve

These procedures are the same as the non-California procedures described earlier.

Carburetor Bleed Air Passage

These procedures are the same as the non-California procedures described earlier.
