There are 2 water tanks/ bottles 1 at the rear, the larger of the 2, which feeds the smaller bottle at the front when required. Access to the rear bottle is gained by removing rear bumper. Access to the front bottle is gained by removing drivers side front wheel and plastic inner wheel arch. Both tanks/bottles have pumps and level sensors which are a push fit into rubber sealing grommets which can leak especially if the washer fluid freezes because not enough washer fluid is added to water to prevent freezing. Jaguar washer fluid states 1 part washer fluid to 4 parts water for protection down to minus 5C, 1 part washer fluid to 1 parts water for protection down to minus 10C.
