Technical Information


The header tank is an important part of the pressurised cooling system.


Its main functions include:


* Providing expansion space for heated coolant

The tank works together with:

* Cooling hoses

* Pressure cap

* Engine cooling passages


Common Symptoms / Reasons for Replacement


Replacement may be required due to:


* Cracked tank body

* Coolant leakage

* Damaged hose connections

* Split seams

* Corrosion around fittings

* Damaged mounting points

Important Diagnostic Information


If coolant is being lost, also inspect:


* Radiator

* Water pump

* Thermostat housing

* Coolant hoses

* Heater hoses

* Pressure cap

* Hose clips

* Head gasket condition

* Other cooling-system joints


Coolant loss does not always mean the expansion tank itself is faulty.


Installation


Before fitting:

* Hose connection positions

* Number of outlets

* Tank shape

* Mounting points

* Pressure cap arrangement

* Overall dimensions


Jaguar used different cooling-system components across the XJS engine range, so do not order based only on vehicle model.
