Alternator Heatshield ERR4859 for 300Tdi

The Alternator Heatshield ERR4859 is designed to protect the alternator from excessive heat generated by the exhaust system on Land Rover vehicles equipped with the 300Tdi diesel engine. By shielding the alternator from radiant heat, this component helps prevent premature alternator failure, electrical issues, and reduced charging performance.

Over time, missing or damaged heatshields can expose the alternator to high temperatures, especially during extended driving or off-road use. This replacement heatshield restores proper thermal protection and is well suited for maintenance, repair, or restoration of 300Tdi-powered Land Rovers.
