Zenoah K116012210 RC Engine Water Jacket Compatible with G230PUM  [K116012210]

Cooling jacket for tuned RC engines

This water cooling jacket, marked K116012210, is built for use with G230PUM engines to assist with thermal regulation during bench tuning and track use. The jacket encloses the engine outer surface to form a routed coolant path and mates with common hobby cooling plumbing while preserving original mounting points.

Fitting is familiar to those who service small engines: place the jacket over the engine body, align the outlet and inlet holes with the engine ports, and fasten using the supplied or factory mounting hardware. Ensure hose runs do not interfere with throttle linkages or moving components to avoid snags.

For tuning and routine maintenance the jacket helps hold a steady operating temperature, which supports repeatable carburettor and ignition adjustments. It is offered as an add-on thermal aid and should be paired with suitable coolant flow and monitoring practices for best results.
