Cold Engine System Test

COLD ENGINE TEST

1. Check the vacuum line for proper connection, cracks, blockage or disconnected hose.

2. Disconnect the # 3 vacuum hose at the purge control diaphragm valve (on the charcoal canister) and connect a vacuum gauge to the hose.
3. Start the engine and allow to idle.

NOTE: Engine coolant temperature must be below 55°C (131°F).

Vacuum should not be available.

- If there is vacuum, replace the thermovalve and re-test.
