3889232 Volvo.Penta Valve housing

For any type of leak (coolant, lube, or fuel) clean up the fluid. If leaking is observed, find the source and correct the leak. If leaking is suspected, check the fluid levels more often than recommended until the leak is found or fixed, or until the suspicion of a leak is proved to be unwarranted.
Accumulated grease and/or oil on an engine or deck is a fire hazard. Remove this debris with steam cleaning or high pressure water.
Air Inlet and Exhaust System
Inspect the piping for the air inlet and exhaust system and the elbows for cracks.
Inspect exhaust bellows for leaks.
Ensure that the air filters are in place.
Ensure that all clamps and connections are secure.
Observe the air cleaner service indicator. Service the air cleaner when the yellow diaphragm enters the red zone, or when the red piston locks in the visible position.Cooling System
Inspect the cooling system for leaks or loose connections.
Inspect the cooling system hoses for cracks and for loose clamps.
Inspect the water pumps for evidence of leaks.
Inspect the fan drive belts for cracks and for deterioration.
Check the coolant level. Add coolant, if necessary. For information on the proper coolant to use, see this Operation and Maintenance Manual, "Refill Capacities and Recommendations".Note: The water pump seal is lubricated by coolant in the cooling system. A small amount of leakage to occur as the engine cools down and the parts contract is normal.Excessive coolant leakage may indicate the need to replace the water pump seal. For the removal of the water pump and the installation of the water pump and/or seals, refer to the Service Manual for the engine or consult your Cat dealer.Driven Equipment
Perform any maintenance that is required for the driven equipment.Electrical System
Inspect the wiring for the following conditions:
Loose connections
Wiring that is worn or frayed
Inspect the ground strap for a good connection and for good condition.
Inspect the engine-to-frame ground strap for a good connection and for good condition.Fuel System
All valves in the fuel return line must be open before and during engine operation to help prevent high fuel pressure. High fuel pressure may cause filter housing failure or other damage.
Inspect the fuel lines for loose fittings and leaks. Ensure that the fuel lines are properly clamped.
Ensure that the fuel is supplied to the engine.
Drain the water and the sediment from fuel tanks daily to ensure that only clean fuel enters the fuel system.If the engine has not been started for several weeks, fuel may have drained from the fuel system. Air may have entered the filter housing. Also, when fuel filters have been changed, some air space will be left in the housing. In these instances, prime the fuel system. See this Operation and Maintenance Manual (Maintenance Section), "Fuel System-Prime" for information on priming the fuel system.Lubrication System

(3) "ENGINE STOPPED WITH OIL COLD" side
(4) "ENGINE AT LOW IDLE WITH WARM OIL" side
(5) "ADD" mark
(6) "FULL" mark
Check the engine crankcase oil level. Maintain the oil level between the "ADD" and "FULL" marks on the "ENGINE STOPPED" side of the oil level gauge. For information on the proper oil to use, see this Operation and Maintenance Manual, "Refill Capacities and Recommendations".
Check for leaks at the following components: crankshaft seals, crankcase, oil filters, oil gallery plugs, sensors, and valve covers.
Inspect the tubes, tee pieces, and clamps on the crankcase breathers.Starting System
Disconnect any battery chargers that are not protected against the high current drain that is created when the electric starting motor is engaged.
Inspect the battery cables for good connections and for corrosion.
Inspect the gauges and/or the control panel for good condition.
Reset the shutoff (if equipped) and alarm components.
