Caterpillar Generator C32

Cooling System Coolant (ELC) - Change

Oil entered the cooling system and coolant is contaminated?

Fuel entered the cooling system and coolant is contaminated?

Cooling system filler cap removed?

Cooling system drain valve opened or drain plugs removed?

Cooling System Coolant Level - Check

Is the coolant level within 13 mm (0.5 inch) of the bottom of the filler pipe?

Is the cooling system filler cap and gaskets in good condition?

Are there any leaks in the cooling system?

Is the oil level between “ADD” mark (Y) and “FULL” mark (X) on the oil level gauge?

Is the oil filler cap clean and properly installed?

Is the total current in any one phase not exceeding the nameplate rating?

Monitor the connector contacts of the differential pressure switch for the air inlet filter.

Battery Electrolyte Level - Check

Ensure a full charge in order to help prevent the battery from freezing.

Inspect the condition of the panel.

Electronic Modular Control Panel 3 (EMCP 3)

Press and hold the Lamp Test button in order to test all of the LED lights and the display screen.

Caterpillar recommends a scheduled inspection of the alternator. Inspect the alternator for loose connections and proper battery charging. Inspect the ammeter (if equipped) during engine operation in order to ensure proper battery performance and/or proper performance of the electrical system. Make repairs, as required.

Check the alternator and the battery charger for proper operation. If the batteries are properly charged, the ammeter reading should be very near zero. All batteries should be kept charged. The batteries should be kept warm because temperature affects the cranking power. If the battery is too cold, the battery will not crank the engine. The battery will not crank the engine, even if the engine is warm.

When the engine is not run for long periods of time or if the engine is run for short periods, the batteries may not fully charge. A battery with a low charge will freeze more easily than a battery with a full charge.

Cooling System Coolant Sample (Level 2) - Obtain

NOTICE: Always use a designated pump for oil sampling, and use a separate designated pump for coolant sampling. Using the same pump for both types of samples may contaminate the samples that are being drawn. This contaminate may cause a false analysis and an incorrect interpretation that could lead to concerns by both dealers and customers.

Refer to Operation and Maintenance Manual, “Cooling System Coolant Sample (Level 1) - Obtain” for the guidelines for proper sampling of the coolant. Submit the sample for Level 2 analysis.

For additional information about coolant analysis, see Special Publication, SEBU6251, “Caterpillar Commercial Diesel Engines Fluids Recommendations” or consult your Caterpillar dealer.

Crankshaft Vibration Damper - Inspect

Misalignment of the engine and the driven equipment

Camshafts correctly timed with the crankshaft

Adjustment of the lash for the fuel injector
