VW T3 Zender coolant level, 2 pin | 251 919 372

This sender is located in your expansion tank and illuminates the dashboard warning light when the coolant drops below the minimum level. It is a two-pin version (OEM 251 919 372) that fits directly into the expansion tank and works reliably on classic Volkswagens. Replace it preventively if you have replaced your radiator or if your current sensor no longer responds, as a non-functioning sensor might leave you with an overheating engine. Combine this with fresh coolant and a new expansion tank for complete cooling system maintenance.
