Hi everyone new here to the site. I have just bought a 1999 S-Type, 35000 miles on clock was only used in the summer months and put away for winter. I got it home and found a coolant leak its leaking from below the expansion tank. I cant see from were. Can anyone tell me how may hoses are there on the expansion tank and could it be the expansion tank itself. Its not a huge leak but is concerning. Its my first S-type So from that area of the car is it likely to be a hose or the tank and how easy is it to access and remove the tank itself or even to get to the hoses. Any help would be appreciated. 

I too had 99 with a similar problem turned out to be the plastic header tank itself riddled with holes.  Expensive job to replace as only source is Jaguar who have begun to market these.  

Most likely the tank itself. Just get a new one.
