Coolant Pump Gasket – VAG 1.4 TSI / 1.4 TFSI | OEM 03C121004J

The water pump gasket on VAG 1.4 TSI and 1.4 TFSI engines seals the pump to the engine block. When it fails, coolant seeps at the pump face — causing coolant loss and overheating risk. This direct replacement gasket restores a leak-free water pump seal.

Fits OEM #03C121004J.
