Warning: Only qualified service personnel should perform this maintenance.

Ensure that the engine can not be started while this maintenance is being performed.

Hot engine components can cause burns. Allow additional time for the engine to cool before measuring/adjusting valve lash clearance.

Ensure that the engine is stopped before measuring the valve lash.

Did you use a designated pump for coolant sampling?

Did you obtain coolant samples directly from the coolant sample port?

Did you place the sample in the mailing tube immediately after obtaining the sample?

Did you avoid collecting samples from expansion bottles and system drain?

Check the battery charger for proper operation. If the batteries are properly charged, the needle of the ammeter will register near “0” (zero).

The battery charger must not produce excessive current during start-up. Alternatively, the charger must be automatically disconnected for start-up.

If the engine has an alternator, the charger must be automatically disconnected during start-up and during engine operation.

Never disconnect any charging unit circuit or battery circuit cable from the battery when the charging unit is operated. A spark can cause an explosion from the flammable vapor mixture of hydrogen and oxygen that is released from the electrolyte through the battery outlets. Injury to personnel can be the result.

Perform the following procedure to charge the battery:

1. Ensure that the charger is turned OFF.

Core cleaned with recommended concentration of cleaner?

Core back flushed with cleaner?

Core steam cleaned to remove residue?

Core washed with hot, soapy water and rinsed thoroughly?

Core dried with compressed air?

Core inspected for cleanliness and pressure tested?

Warning: This procedure requires trained personnel with PPE!

Cylinder Head Grounding Stud - Inspect/Clean/Tighten

Inspect the OEM harness for good connections and condition.

The electrical grounding stud must have a wire ground to the battery.

Tighten the electrical grounding stud at every oil change.

Ground wires and straps should be combined at engine grounds.

All grounds should be tight and free of corrosion.

If the connections are corroded, clean the connections with a solution of baking soda and water.

Keep the electrical grounding stud and the strap clean and coated with MPGM grease or petroleum jelly.
