Description
Overview:
The Heat Deflector is a genuine Husqvarna OEM part designed for the 357 XP and 359 chainsaws. Made from heat-resistant, formed stainless-steel plate, it sits by the exhaust area to shield nearby components from radiant and convective heat. By protecting plastics, wiring, fuel lines and the crankcase area, it helps the saw run reliably under load and maintain stable performance during long cutting sessions. The precise shape and factory mounting points ensure a secure fit without modification, preserving airflow around the cylinder and muffler. This durable component reduces heat-related wear, supports operator comfort by limiting heat transfer towards the handle, and helps extend the service life of your machine.
