Can anyone tell me whether the washer nozzles mounted on the hood are jag equipment or will any do ?

Thanks in anticipation

 

I don't expect Jaguar paid for special ones as their annual production was so small, so provided ones you find will fit the fixing hole, and take the flexible tubes, and also will adjust correctly, they should be OK. You can buy new ones from Jaguar spares specialists, and I doubt these are originals at all.

 

The $4 set from Canadian Tire are fine.
