X type water temperature gauge not giving a reading!

[ZhanjiangkidinaJaguar]

Hi,

 

I love my Jaguar X type  but I am a driver not a mechanics, so I need some help please.

Yesterday my water temperature gauge was fine and after driving for a short time it gave it's usual reading of approx half way between cold and hot.

Today,...nothing!

 

What should I check, or what may need changing?

 

Thanks

Hi Paul,

 

I would firstly check the coolant level....if it has dropped off the level drastically then this can lead to a false reading and expensive repair bills if completely drained of coolant.

If the level is fine then it could be the Coolant Temperature Sensor (CTS) or the wiring attached to it.

Lastly, a faulty instrument panel could be to blame.

I suggest you take the car to a specialist to diagnose the fault by plugging into the electronics with a scan tool.

 

Hope this helps?
