99724A 2 Mariner SHOCK ABSORBER (BLACK)

Never add coolant to an overheated engine; allow the engine to cool first.Check specific gravity of antifreeze solution frequently in cold weather to assure adequate protection.Coolant should be drained and replaced "Every 2000 Service Meter Units." With additions of Caterpillar Cooling System Conditioner or the use of Caterpillar Coolant Conditioner Elements as recommended, the drain period can be extended to "Every 4000 Service Meter Units".All water is corrosive at engine operating temperature. The cooling system should be protected with conditioner at all times regardless of concentration of antifreeze.When changing coolant or on initial fill, use a 3 percent solution of Caterpillar Cooling System Conditioner. This can be accomplished with .5 liter of conditioner for every 15 liters of cooling system capacity (1 pint for every 4 gallons). This concentration can be maintained by conditioner additions "Every 250 Service Meter Units." Add .5 liter of conditioner for every 76 liters of cooling system capacity (1 pint for every 20 gallons).Most systems will require 2 liters (2 quarts) of conditioner at initial fill and .50 liters (1 pint) "Every 250 Service Meter Units."Do not use Caterpillar Cooling System Conditioner with Dowtherm 209 Full-Fill coolant. Follow the recommendations provided with the Dowtherm 209 Full-Fill coolant.Never use both liquid cooling system conditioner and coolant conditioner element at the same time.When permanent antifreeze and water solutions are used in the cooling system, the solution should be drained and replaced "Every 2000 Service Meter Units".When cooling system conditioner additions are made "Every 250 Service Meter Units" as recommended, this change period can be extended to "Every 4000 Service Meter Units or Two Years."
If the engine is to be stored or used in an area with below freezing temperatures, the cooling system must be protected to the lowest expected ambient temperature.Operate with a thermostat in the cooling system all year-round. Problems can arise without a thermostat in the cooling system.Use clean water that is low in scale forming minerals, not softened water.Always recheck the coolant level when the engine reaches normal operating temperature. Add coolant as necessary to bring up to proper level.Filling faster than 19 liters (5 U.S. gallons) per minute can cause air pockets in the cooling system.Premix the antifreeze solution to provide protection to the lowest expected ambient temperature.Electrical System
When using jumper cables to start the engine, be sure to connect in parallel: POSITIVE (+) to POSITIVE (+) and NEGATIVE (-) to NEGATIVE (-).When using external electrical source to start the engine, turn the disconnect switch off and remove the key before attaching jumper cables.
Scheduled Oil Sampling
Use Scheduled Oil Sampling to monitor engine condition and maintenance requirements. Each oil sample should be taken when the oil is hot and well mixed to insure a sample which is representative of the oil in the compartment. Samples should be taken at each engine oil change. Consult your authorized Caterpillar engine dealer for complete information and assistance in establishing a scheduled oil sampling program for your engine.Fuel System
Fill the fuel tank at the end of each day of operation to drive out moisture laden air and to prevent condensation. Do not completely fill the tank. The fuel expands when it gets warm and may overflow.
Water and sediment should be drained from the fuel tank at the start of each shift or after the fuel tank has been filled and allowed to stand for 5 to 20 minutes. Drain the fuel tank and water seperator of moisture and sediment as required by prevailing conditions.After changing the fuel filters, always prime the fuel system to remove air bubbles.General
Accumulated grease and oil on the engine is a fire hazard. Remove this debris with steam cleaning or high pressure water, at least every 1000 service meter units or each time any significant quantity of oil is spilled on the engine.Wipe all fittings, caps and plugs before servicing.
