Temperature Gauge Issues

[Rezallini]

Hi, I've had temperature gauge problems for almost a year on my 2003 C8 2.2 HDI. Thought I have a go at fixing it myself. Can anyone tell me where is the sender located on the engine? Or any other help/advice? Thanks.

Welcome to the forum.

 

What exactly is the problem ?  If you use a code reader with live data you can see what temperature the sensor is giving to see if it seems about right without going to the bother of replacing it. The sensors are usually located near or on the thermostat housing.

Hi and thanks for the reply. The gauge stopped working last year and it occasionally showed the right temperature. Other times it would go right up for a few seconds. It hasn't moved for a few months though. Having recently replaced the reverse light switch, I felt encouraged to have a go at replacing the temperature sender as it may be the cheapest option to try. What would you do (suggest)?

It is probably not the temperature sensor since if that was not working the engine would not start easily or run very well and you have not mentioned that. Also if faulty they often go to maximum quite soon after starting the engine and bring up a high temperature message http://www.citroen-owners-club.co.uk/citroen/topic/8589-temperature-gauge-fault-sender-unit/

 

Possibly there is a loose or bad connection on the gauge.

 

If you want to try the temperature sensor it is located on the gearbox side of the thermostat housing at the end of the cylinder head. Some are screwed in, others are held by a clip.
