Check the vacuum when hot:1. Turn the ignition switch OFF.2. Block the rear wheels and setthe parking brake.3. Jack up the front of the vehi-cle and support it with safetystands.4- Start the engine. Hold theengine at 3,000 rpm with noload (in Park or neutral) untilthe radiator fan comes on, thenlet it idle.5. Check for vacuum at the vacuum hose with transmissionin gear (A/T in E position,M/T in 'l st gear) after startingrne engrne.6. Ouickly raise the engine speedto 3,000 rpm.
