3. Shake the core vigorously to eliminate any trapped debris.4. Wash the core with hot, soapy water. Rinse thoroughly with clean water.5. Dry the core with compressed air. Blow air in reverse direction of normal flow. Use all necessary safety equipment while using compressed air.6. Inspect the system to ensure cleanliness and install the core.Coolant Analysis
Obtain
There are two types of coolant analysis that can be performed. First, the concentration of supplemental coolant additives (conditioner) should be checked regularly for over or under concentration. The intervals recommended for re-charging with supplemental coolant additive should be adequate for many users, but it is a good idea to periodically check the concentration.For checking the concentration of coolant conditioner, Caterpillar offers an 8T5296 test kit.At overhaul time, a further coolant analysis may be desirable. For example, suppose considerable deposits are found in the water jacket areas on the external cooling system, yet supplemental coolant additive concentrations were carefully maintained. Chances are that the coolant water had minerals which deposited on the engine over time. One way to verify the water condition, or to be sure of new water at fill time, is to have a water analysis conducted.Full water analysis can sometimes be obtained locally by contacting your local water utility company or an agricultural agent. Private laboratories are also available. Many Caterpillar dealers and customers send water samples to:L.O.C.C. Corporation

To analyze a water sample, most laboratories need approximately 250 ml (1/2 pint) of water. Check the lab you use for details about labeling and shipping.After Failure Overhaul
If you experience a major engine failure which requires removal of the engine, there are also many After Failure Overhaul options available. An overhaul should be performed if your block or crankshaft needs to be repaired.If the block and/or crankshaft is repairable, then the cost of an overhaul should be between 40 and 50 percent of the cost of a new engine (with like exchange core).This lower cost can be attributed to Caterpillar "designed-in" features that include:* Regrindable crankshaft* Undersize bearings, if needed* Cat dealer and Caterpillar Remanufactured exchange components Dealer Exchange Components - This cost cutting service permits you to exchange worn engine components for quality Caterpillar dealer rebuilt components on an over-the-counter basis. When you need them, these parts are ready for a substantial savings in both time and money. Caterpillar Remanufactured Components - Manufacturing techniques and processes are used to restore your components to "like-new" performance capabilities and are exchanged for your existing parts. The processes used result in an end product that conforms to Caterpillar's original functional specifications.The following is a list of (R) Remanufactured components that can be found in the Parts Book and currently being offered by Caterpillar* in many countries:* Short block* Cylinder pack1* Cylinder head - bare casting* Cylinder head - assembled* Crankshaft - undersized*** Crankshaft - upgrade to new* Complete turbocharger* Turbocharger Piece Parts* Turbocharger Cartridges*
