Which tank is for coolant?
The cooling system is constantly under pressure with the use of an expansion tank. Instead of sending the expanding coolant to the tank once it reaches a certain pressure, the coolant is always cycled through the radiator and out to the expansion tank.

Which Jaguar has a V12?
Any Jaguar V12 The Jaguar XJ-S and XJ-12 might be the most affordable V12 cars you can buy, but that affordability comes at the expense of reliability. The Jaguar XJ-12 has two radiators fed by two coolant tanks, with two fuel tanks, two fuel pumps and a battery that has its own thermostatically controlled cooling fan.
How does a Jaguar XJ-S radiator work?
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).
Where does the coolant come from on a JAG?
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). Then the coolant from the right bank comes in, mixing with this already-cooled fluid.
When did the cooling system change on a Jaguar?
Somewhere around 1988 — possibly coinciding with the introduction of long-life phosphate-free coolant — Jaguar went from the overdesigned drain cock to no drain cock at all. On later cars, it is necessary to disconnect the lower radiator hose to drain the coolant. Wearing a tux is not recommended.
Is there a leak in the XJ-S 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 V-12 cooling system.

How do you remove the radiator on a Jaguar XJ?
Use the drain cock to neatly drain the coolant into a container, and then remove the radiator hose to flush water through. Both the official Jaguar manual and the Haynes manual state that removing the radiator requires discharging the air conditioner freon circuit. They lie. In fact, as Jim Isbell reports,
Do you need Jaguar XJS parts for a coupe?
Depending on your version you may need Jaguar XJS parts for a coupe, a convertible, a V-12 or straight 6 engine. If you have a V-12 the cooling systems needs to be maintained often as it may result in overheating because of the small engine bay in which case it can result in a blown head gasket.
