Cooling systems are the same for all vehicles, depending on years ,, in your case all you have is a fan, relay, and sensor, controlled by a circuit with a fuse, so , always check fuses first, if bad replace,, if not, unplug the fan at the connector,, use a jumper wire to supply the fan with 12 volts direct from the battery ,, if it starts, its not the fan, if it doesn't the fan needs replacing, if that checked out to be good,, backtrack to the fan relay, ( usually the problem) locate it in the under the hood fuse box, it will be listed on the tag on the underside of the fuse box cover ( or in the owners manual itself) you should have a couple of the same relay in this box,, ( Jaguar uses the same relay for a number of items) locate the one for the fan, and switch it out for one that runs a system you know is working, start the vehicle,, and let it run until the thermostat opens,, watch the temp gauge don't let it move up to high. soon after , the fan should start , if by now the system isn't working, its going to normally be a short in that circuit, and would have to looked at by a trained professional with knowledge in electrical circuits
