How to test the Jaguar coolant temperature sensor?
Use a bit of wire, paperclip, etc. and plug one end each into the harness connector sockets. Doing this “fools” the ECU into thinking the engine is hot, since there is now no (or minimal resistance) measured. The ECU will not add pulse width correction to the injectors…so no additional fueling is supplied.
Where is the CTS located on a Jaguar?
Prior to discussing failure of the CTS, or the harness wiring, we need to understand the function of the CTS…. The CTS is an important primary engine sensor, and is typically threaded into a port on the B bank thermostat housing…(for the V12 engine).
What are the pins on a Jaguar XJ6?
Info provided by a series 3, 1986 Jaguar XJ6 owner, on April 2017, says the pins at the ECU are 13 and 17 (17 being ground). The above testing procedures require a fundamental knowledge of using either a digital readout/or analog meter, and setting the meter dials on the correct position.
How to check the coolant level on a Jaguar XJ?
Visually check the coolant level. If low, continue with the procedure below. 2. If the coolant level is below the bottom of the filler neck, top up with Jaguar Antifreeze D542 (diluted 50:50 with clean water) until the coolant rises to the bottom of the filler neck. 3. Start the engine and allow it to run at idling speed.
Why is the low level sensor on my Jaguar not working?
Once the coolant level has dropped, it is also possible that the captive float which actuates the low level sensor may stick in the down position, leaving a warning on even after the cooling system has been refilled.
What kind of engine does the Jaguar XK8 have?
Introduction The XK8 is powered by an all new Jaguar 4-litre V8 engine known as the AJV8. Its Engine Control Module
What should I know about the XK8 engine management system?
THE XK8 ENGINE MANAGEMENT SYSTEM AND ELECTRONIC ENGINE CONTROL MODULE Mark Gallagher B.Eng. C.Eng MIEE Abstract The increasing demand for feature enhancements on passenger vehicles combined with more stringent emissions and legislative requirements world-wide has lead to a high level of complexity within engine control des,

What does a Jaguar climate control system do?
Jaguar Climate Control Systems provide vehicle occupants with year-round automatic temperature and humidity control as selected on the control panel. The vehicle heating and air-conditioning systems are the foundation for providing the warm, cool or combined warm/cool air necessary to meet the desired conditions.
Where is the overflow tank cap on a Jaguar XJ6?
For a Series III XJ6, replace the header tank cap with a flat non-venting cap and the overflow tank cap with a 15 lb pressure cap (The header tank is located on the front of the coolent rail on the top, intake side of the engine, the overflow tank is on the fender wall).
What’s the boiling point of coolant in a Jaguar?
The same goes for your cooling system. When your system operates at it’s rated 15 psi pressure (XJ6 Series III) the boiling point of the coolant circulating inside of your head and block is much higher than if your system is operating at ambient pressure.
Why is the CTS on my Jaguar not working?
The CTS, the harness wiring, and the harness connector, are all prone to failure. The CTS pin contacts, and the wiring harness contacts are also prone to failure due to corrosion.

Where is the engine coolant temperature sensor ( ECT )?
ECT is No3 in the pic below, update your profile to show which engine you have. thank you very much . but it has no wires ?!!!?!!! I Have Donated ! Grey plug with two wires plugs into the sensor, to the left of the inlet manifold, very easy to replace, literally 5 minutes.
How to check engine temp on Jaguar X350?
TonyXJR bought a thermostat kit and changed it quite successfully. Also 57jam89 in the S Type forum describes a process for checking engine temp using the button on the indicator stalk, i’m going to see if that works on the X350. After i’ve checked I have a button on my indicator stalk!!!!!

What happens to the coolant in a new Jaguar?
On a new vehicle, these pockets of air may take some considerable time to be purged, resulting in a gradual drop in the coolant level. This process may eventually lead to illumination of the coolant warning lamp by the low level sensor located in the coolant reservoir.
