T4,G3 Alternator - 1995-98 (2.5TDI) - 90 Amp

This 90 amp alternator, manufactured by HELLA, is a high-quality replacement designed to deliver stable and reliable electrical output across a range of Volkswagen diesel and petrol engines. It is ideal for vehicles running higher electrical loads such as heaters, cooling fans, glow plugs, lighting, and auxiliary accessories.

The alternator works by converting mechanical energy from the engine into electrical power, supplying current to the vehicle’s electrical systems while keeping the battery fully charged. A failing alternator can lead to flat batteries, dim lights, warning lamps on the dashboard, and poor starting—especially noticeable on diesel and VR6 engines.

Built to OEM specifications, this HELLA alternator offers consistent charging performance, robust internal components, and long service life. It mounts directly in place of the original unit using standard fixings, making installation straightforward for both professional workshops and experienced DIY users.
