Engine Cooling Components
WARNING: This page is about a different car, the 2002 Jaguar XKR and 2002 Jaguar XK8. However, it is still accessible from the selected car via links, so may be relevant.
Engine cooling is via a low volume, high velocity system which achieves a very fast warm up. The temperature of the combustion chambers is reduced along with a more even temperature distribution. The temperature of the bores is increased.
From the pump, coolant flows into each bank of the cylinder block. In each bank, approximately 50% of the coolant cools the cylinder bores and the remainder is diverted through the bypass gallery to the cylinder head.
With the thermostat closed, coolant returns directly to the pump through the bypass on the thermostat housing.
With the thermostat open, coolant returns to the pump via the radiator.
The cooling system uses a mixture of soft water and Jaguar Anti-Freeze/Inhibitor (WSS M97B44-D).
