SEBU7899-05 71 Maintenance Section Coolant Sample (Level 1) - Obtain i04333559 Coolant Sample (Level 1) - Obtain SMCS Code: 1350-008; 1395-008; 1395-554; 7542 Testing the engine coolant is important to ensure that the engine is protected from internal cavitation and corrosion. The analysis also tests the ability of the coolant to protect the engine from boiling and freezing. S·O·S Systems Coolant Analysis can be done at your Cat dealer. Cat S·O·S coolant analysis is the best way to monitor the condition of your coolant and your cooling system. S·O·S coolant analysis is a program that is based on periodic samples. g00285520 Illustration 35 Cooling system filler cap Note:
Obtaining a Coolant Sample (Level 1) is optional if the cooling system is filled with one of the following coolants: Cat ELC (Extended Life Coolant)., Cat ELI (Extended Life Inhibitor), and Conventional Heavy-Duty Coolant. Pressurized System: Hot coolant can cause seri- ous burns. To open the cooling system filler cap, stop the engine and wait until the cooling system components are cool. Loosen the cooling system pressure cap slowly in order to relieve the pres- sure. Note: Obtain a Coolant Sample (Level 1) if the cooling system is filled with any of the following coolants: Cat DEAC, Cat SCA, and Conventional Heavy-Duty Coolants. 1.
Remove the cooling system filler cap slowly in order to relieve pressure. For additional information about coolant analysis and about other coolants, see this Operation and Maintenance Manual, “Fluid Recommendations” or consult your Cat dealer. 2. Maintain the coolant level within 13 mm (0.5 inch) of the bottom of the filler pipe. If the engine is equipped with a sight glass, maintain the coolant level to the proper level in the sight glass. Sampling Conditions If the engine is equipped with a sampling port, the engine should be running at operating temperature when the sample is obtained. If the engine is not equipped with a sampling port, the coolant should be warm.
Use the following guidelines for proper sampling of the coolant: Complete the information on the label for the sampling bottle before you begin to take the samples. g00103639 Illustration 36 Keep the unused sampling bottles stored in plastic bags. Typical filler cap gaskets 3. Clean the cooling system filler cap and check the condition of the filler cap gaskets. Replace the cooling system filler cap if the filler cap gaskets are damaged. Reinstall the cooling system filler cap. Obtain coolant samples directly from the coolant sample port. You should not obtain the samples from any other location. 4. Inspect the cooling system for leaks.
Keep the lids on empty sampling bottles until you are ready to collect the sample.
