WARNING
Some state and federal agencies have determined
that used engine oil can be carcinogenic and cause
reproductive toxicity. Avoid inhalation of vapors,
ingestion, and prolonged contact with used engine
oil. If not reused, dispose of in accordance with local
environmental regulations.
WARNING
To reduce the possibility of personal injury, avoid
direct contact of hot oil with your skin.
Locate the appropriate port for measuring oil pressure. On
most engines a port can be found adjacent to the ECM
along the main oil gallery. If this port is not accessible,
another port can be located on the top of the oil filter
head.
Remove the plug.
NOTE: It is preferred that oil pressure be checked at the
main oil gallery, if accessible.
Install a Compuchek® fitting.
CAUTION
If the lubricating oil pressure does not develop within
15 seconds, shut down the engine to reduce the
possibility of internal damage.
Connect a pressure gauge. Start the engine.
Allow the engine to run and achieve operating
temperature. Check for leaks.
Record the lubricating oil pressure readings at idle.
