KIT-GASKET-SCH 2894093 - Caterpillar

Note: Obtaining a Coolant Sample (Level 1) is optional if the cooling system is filled with Cat ELC (Extended Life Coolant). Cooling systems filled with Cat ELC should have a Coolant Sample (Level 2) obtained.Note: Obtain a Coolant Sample (Level 1) if the cooling system is filled with any other coolant instead of Cat ELC including the following coolants:
Commercial long life coolants that meet the Caterpillar Engine Coolant Specification -1 (Caterpillar EC-1)
Cat DEAC (Diesel Engine Antifreeze/Coolant)
Commercial heavy-duty coolant/antifreeze

Recommended Interval
Type of Coolant Level 1 Level 2
Cat DEAC Every 250 service hours Every year(1)
Conventional heavy duty-coolant
Commercial coolant that meets the requirements of the Caterpillar EC-1 standard
Cat ELC or conventional EC-1 coolant Optional Every year(1)
(1) The Level 2 Coolant Analysis should be performed sooner if a problem is suspected or identified.
Always use a designated pump for oil sampling, and use a separate designated pump for coolant sampling. Using the same pump for both types of samples may contaminate the samples that are being drawn. This contaminate may cause a false analysis and an incorrect interpretation that could lead to concerns by both dealers and customers.
Note: Level 1 results may indicate a need for Level 2 Analysis.Obtain the sample of the coolant as close as possible to the recommended sampling interval. To receive the full effect of S O S analysis, establish a consistent trend of data. To establish a pertinent history of data, perform consistent samplings that are evenly spaced. Supplies for collecting samples can be obtained from your Cat dealer.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.
Keep the unused sampling bottles stored in plastic bags.
Obtain coolant samples directly from the coolant sample port. You should not obtain the samples from any other location.
Keep the lids on empty sampling bottles until you are ready to collect the sample.
Place the sample in the mailing tube immediately after obtaining the sample to avoid contamination.
Never collect samples from expansion bottles.
Never collect samples from the drain for a system.Submit the sample for Level 1 analysis.For additional information about coolant analysis, see this Operation and Maintenance Manual, "Refill Capacities and Recommendations" or consult your Cat dealer.
