892267A51 Mariner PUMP KIT, Fuel (Also includes cover to body o ring 25-892267530)

Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, PERJ1017, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat® products.Dispose of all fluids according to local regulations and mandates.

Illustration 1 g00439083
Tooling T2 Coolant/Battery Tester Gp
Check the coolant frequently in cold weather for the proper protection against freezing. Use Tooling (T2) to ensure adequate freeze protection. The tester gives immediate, accurate readings. The tester can be used for antifreeze/coolants that contain ethylene or propylene glycol. The tester is also used to check the condition of batteries (specific gravity). Instructions are provided with the tester.Making the Correct Antifreeze Mixtures
Adding pure antifreeze as a makeup solution for the cooling system top-off is an unacceptable practice. Adding pure antifreeze increases the concentration of antifreeze in the cooling system. Pure antifreeze increases the concentration of the dissolved solids and the undissolved chemical inhibitors in the cooling system. Add the antifreeze and water mixture in the same concentration as your cooling system. Refer to the engine Operation and Maintenance Manual.Testing the Supplemental Coolant Additive and the Glycol
Refer to the engine Operation and Maintenance Manual for further information about testing the cooling system.Testing for Air and/or Exhaust Gas in the Coolant
Air and/or exhaust gas in the coolant causes foaming and aeration. Bubbles in the cooling system reduce the heat transfer and the pump flow. Pockets of air or gas can prevent coolant from contacting parts of the engine. The pockets allow hot spots to develop.If the cooling system is not filled to the proper level, air can be trapped in the system. Filling the cooling system too quickly can also trap air in the system. Leaks from components such as aftercoolers and hoses can allow air to enter the system. The inlet of the water pump is a potential location for the entry of air.To help prevent air from entering the cooling system, fill the system slowly. The radiator cap must be removed when filling the system from the bottom. Make sure that all the hoses and pipe connections are secure.If the cylinder head is loose or cracked, exhaust gas can enter the cooling system. Exhaust gas can also enter the cooling system through internal cracks and/or defects in the cylinder head gasket.Air and/or exhaust gas in the cooling system can cause overheating.Test Preparation
Make sure that the cooling system is filled to the proper level.
Illustration 2 g00769076
Remove the plug from the radiator (if equipped). Install a Tooling (T5) into the hole for the plug.
Fill a clear container with water and place the other end of Tooling (T5) into the container.Test Procedure
Start the engine.
Operate the engine until normal operating temperature is reached.
Observe the end of the hose in the clear container.A bubble may rise occasionally from the hose. An occasional bubble is normal.Air and/or exhaust gas in the coolant is indicated by a stream of bubbles.Testing the Radiator Fan (If Equipped)
