G290PUM Coolant Jacket Compatible with Zenoah K577901901 RC Engines  [K577901901]

Compact coolant jacket for Zenoah K577901901

This Zenoah K577901901 G290PUM water cooling jacket is made for RC-scale use, creating an external coolant route that assists with engine temperature management while the model is in use. It is intended as a component within a broader cooling arrangement, not as an independent unit.

Its design provides a defined channel for circulating coolant so that tubing and a pump can form a closed-loop system around the engine. This helps reduce temperature swings during longer runs and allows straightforward evaluation of cooling changes during testing.

Installation generally involves locating the jacket around the engine housing, attaching flexible coolant lines to the inlet and outlet, and reusing the engine's fasteners to secure the jacket. Typical hobby hand tools are enough for the job, but always confirm fitment before tightening everything down to avoid clashes with mounts or accessory parts.

Keep the system well maintained by checking hoses and connections, replacing worn parts, and flushing the loop if contaminants build up. Always verify that the jacket suits your specific engine model and cooling components prior to purchase and use.
