FAQ

Q1: Is this heat exchanger a direct fit for my Cummins KTA19-M3 marine engine?

This assembly (3008844/3968807) is designed for the K19/KTA19 platform. However, marine configurations can vary based on heat exchanger orientation, raw water pump location, and mounting brackets. We strongly recommend comparing your old part number and the physical dimensions (particularly the end cap and tube bundle layout) with the images provided. If you have your engine serial number (ESN), please contact us to confirm 100% compatibility.

Q2: What maintenance is recommended for this heat exchanger?

Regular maintenance is crucial for longevity. We recommend inspecting the zinc anodes (sacrificial anodes) every 250 hours of operation and replacing them if more than 50% consumed. The tube bundle should be cleaned annually to remove scale and debris from the raw water side. Use a quality coolant with proper corrosion inhibitors on the fresh water side. Never operate the engine without coolant or with the heat exchanger dry.

Q3: Can this part be used in a generator set application, or is it only for marine use?

While the part number is commonly listed for marine use, the K19 engine platform shares the same block and cooling system architecture across marine, generator, and industrial applications. This heat exchanger assembly is physically compatible with many K19 generator set configurations. However, generator sets often use a different mounting and piping arrangement. Verify that the inlet/outlet port sizes and locations match your generator’s cooling system. For dedicated generator applications, please check your existing part number.
