Zenoah K116012210 Water Cooling Jacket G230PUM Engine Fitment  [K116012210]

RC engine external cooling jacket

The K116012210 water cooling jacket is a purpose-built accessory for G230PUM engines that helps manage external engine temperature during bench work and track use. The jacket encases the engine outer surface to create a routed coolant channel and connects with common hobby cooling plumbing while preserving standard mounting positions.

Installation is straightforward for those used to servicing small engines: place the jacket around the engine block, match the jacket openings to the engine ports, and secure using factory mounts or supplied fixings. Ensure hoses are routed away from moving linkages and that clamps are tight to prevent leaks.

When tuning and maintaining the engine the jacket helps maintain repeatable operating temperatures, improving consistency in carburettor and ignition settings over multiple runs. It is intended as an auxiliary cooling solution and works best with monitored coolant flow and appropriate system checks.
