ENGINE VACUUM CHECK
The engine vacuum that develops in the intake line is a good indica-
tor of the condition of the engine. The vacuum checking procedure
is as follows:
1) Warm up engine to normal operating temperature and make
sure that engine idle speed is within specification.
NOTE:
After warning up engine, place transmission gear shift le-
ver in "Neutral" and set parking brake and block drive
wheels.
2) Stop engine and disconnect vacuum hose between vacuum
pipe and intake manifold from vacuum pipe.
3) Connect special tools (vacuum gauge and hose joint) to vacu-
um hose of intake manifold side.
