Can a Jaguar XJ-S have a cooling system?
In theory, leak sealers will not solidify until they come in contact with air; however, there is always a little air inside a cooling system, and in the case of the XJ-S there is apparently enough to cause trouble. Please, do not use any leak-sealing substance within the V12 cooling system.
What causes the XJ-S cooling system to overheat?
Check the radiator for blockage or sludge. Crud in the system will cause overheating under all conditions, but usually more at speed than at idle. Suspend the thermostats in a pan of water on the stove and bring them to a boil. Do not let them contact the bottom of the pan.

RADIATOR: The XJ-S radiator is a side-flow radiator divided into a top third and a bottom two-thirds. The coolant coming from the left bank, via the left side thermostat, enters at the top left and flows left-to-right through the top third (it cannot go directly down to the outlet because there is an internal baffle in the radiator).
