Mondeo - engine runs cold, fans always on

[arcticgoldfish]

For quite some time, my 05 Mondeo 2.0 TDCI has run cold. Under load, temperature gauge is normal, but when you stop / idle the temperature slowly drops. I've noticed that the fans are always on - including when I start from cold. Other than a short of the fan, any pointers as to what causes the fans to default to on?

The fan comes on with the air conditioning.

I've got a similar issue with my X-Type (same engine). In winter the temp gauge can drop down to the 1/4 temp mark when going downhill.
Apparently there is a 2nd thermostat for the oil cooler, which often fails open. I've yet to check out the cost of replacing it but will do shortly as it's taking an age to warm up these days.

You need to change one of or both the thermostats, then it will get up to and stay at operating temperature.
