Changing the thermostat on a 2001 2.4JTD
The normal engine temperature shown on the gauge has gradually fallen until it now barely registers unless the car is driven hard or is standing in traffic. I'm pretty sure the thermostat is leaking, since the rad is always warm, so I need to change the stat. Lots of people say it's a pig of a job, but I'll have a go if someone can give me some basic instructions on how to do it.
Finding the stat would be a good start, I guess from the pipework it must be somewhere near the battery, but it's all a bit crowded under there.
