FAQ

Q: How can I confirm this pump fits my specific engine?

A: The pump is designed for the K19 engine. To confirm exact fitment, please check the part number on your existing water pump. It should read 3074540. You can also cross-reference your engine serial number (ESN) with our sales team to ensure compatibility with your specific marine or generator application.

Q: What is the installation procedure for this marine water pump?

A: Installation should be performed by a qualified diesel mechanic. Key steps include draining the coolant, removing the old pump, cleaning the mounting surface, transferring any fittings (if necessary), installing a new gasket, and torquing the bolts to specifications. Always use fresh coolant and bleed the system after installation to prevent air locks.

Q: What maintenance is required for this high-pressure water pump?

A: Regularly inspect the pump for leaks, unusual noises, or vibrations during operation. Check the coolant level and condition periodically. In marine environments, flush the cooling system with fresh water after extended use in saltwater to prevent sediment buildup. The pump is maintenance-free internally, but the drive belt and tensioner should be inspected at every service interval.
