CYLINDER GP-LH 8J5727 - Caterpillar

Do not use any Methoxypropanol-based antifreeze or coolants such as Dowtherm 209 Full-Fill coolant in the cooling system. Methoxypropanol will cause some seals and gaskets to deteriorate and fail.
4. Maintain coolant level to within 13 mm (1/2 in) below the bottom of the filler tube or to the proper level (upper half) on the sight glass, if equipped. Add premixed coolant if necessary to bring the coolant to the proper level.Refer to the topic Cooling System Specifications in the Maintenance section for additional information about coolant mixture and supplemental coolant additive.5. Start the engine and check for leaks or damaged piping. Allow the coolant level to stabilize. Inspect the cooling system pipes and lines for leaks and/or damaged connections. Make repairs if necessary. Install the filler cap.Cooling System Cleaning
Approximately one week prior to draining the cooling system (at Every Two Year maintenance interval), add 2 liter (1/2 U.S. gal) of Caterpillar Cooling System Cleaner, 6V4511, for every 30 liter (8 U.S. gal) of cooling system capacity.Continue to operate the engine for one week before draining.Refer to the topic, Cooling System-Clean/Flush in this publication or your Caterpillar dealer for more detailed information.Exhaust System
Inspect/Check For Leaks
Handle the soft-wrap shields carefully. Do not tear the stainless steel foil inside the heat shields. Torn foil will let the insulation absorb flammable liquids and a fire can result from engine heat. Any torn stainless steel foil inside the soft-wrap heat shields should be replaced.
Removal of exhaust manifold shields will be necessary to thoroughly inspect the exhaust system. Remove the exhaust shields and protect them. Damage could result to the shields when working on or around them. Check the exhaust system for leakage. Inspect the exhaust system bellows and connections for cracks, leaks and loose fasteners. Be sure to check around the gaskets and bellows assemblies. If leakage is discovered, replace the necessary components. Make repairs as necessary. Refer to the Service Manual for the necessary procedure.Electric Prelube Pump (If Equipped)
Lubricate with MPGM
Lubricate the two pump motor bearings. Use a hand operated grease gun and apply one pump of MPGM grease to each fitting.Inspect hoses and fittings for leaks and electrical connections for damaged or frayed wires.Engine Protection Devices
Check Shutoff Controls and Alarms For Proper Operation
Refer to the Service Manual for the procedure. All engine protective devices must be checked and maintained to provide the engine with proper protection if a component malfunction or failure should occur. Never use the Emergency Shutdown controls for a normal stopping procedure.Inspect Generator
Visually inspect the generator. Check for loose, broken, or damaged wiring or components. The inspection only takes a few minutes and could avert a potential problem that could cause your generator to fail. Refer to the OEM manual for maintenance instructions.Operational Checks
Start the engine. Use the starting procedure found in the Engine Starting topic in this publication.The following operational checks are intended to check the generator operation and the engine starting, lubricating and fuel systems as well as overall operation. The checks should take no longer
