For vehicles without air conditioning only. The GT3 diagram identifies the generator separately; it does not establish belt compatibility. Check fitment for your specific vehicle (model, year, engine) before ordering.

What This Product Does

Driven mechanically by the engine, the alternator produces electrical energy to recharge the battery and supply onboard equipment. The belt provides the rotational drive, making its condition and routing relevant to charging-system diagnosis.

Functions

• Generates electricity with the engine running.
• Recharges the vehicle battery.
• Drives the alternator through the belt.

Symptoms of Fault

• Battery warning indicator or low charging output.
• A frequently discharged battery or slow cranking.
• Flickering or unusually dim lighting.
• Intermittent operation of electrical equipment.
• Bearing whine or belt squeal.

Similar symptoms can originate elsewhere in the charging system; testing is needed to establish the cause.

Why Replacement Matters

Replacing an alternator with a verified fault can restore the charging supply. Examine the battery, belt drive, pulley alignment and electrical connections during diagnosis so that associated defects are addressed alongside the failed component.

FAQs

Does battery discharge necessarily indicate alternator failure?
No. Assess battery health, charging cables and earth connections before deciding which component needs renewal.

Which checks are useful before fitting?
Test charging output with electrical consumers switched on, then inspect belt condition and the main supply connections.

Can Manual and Tiptronic fitment be assumed to match?
No. Verify transmission specification, production details and the recorded generator cutoffs; the model list alone does not resolve every application.
