I seem to be having the dreaded random overheating of my 2001 s-type 4.0L Jag. Im fairly sure this is due to the coolant tank cracking , as i was searching online i came across this item that seems to be compatible with my car. Before i buy id like to get the opinions of the members here whether or not this would fit ?

 

Well No, Your VIN will be below M45254 given the age so part # C2C34318 is the one you want LHD

Does the picture in the add look the same as yours?
