Running Cold

[dc6839]

During this cold snap my 2003 Vectra 2l Dti has been running very cold, at most times below the 80 mark on the temp guage and it takes a long time for the heater to warm up. I am told that this is usual (this being my first diesel car) but I wondered if there is a quick, easy, and above all, safe way for me to increase the temperature that the engine runs at ?

Or should I just accept that is what diesels do and wait for the summer ?

Thanks

They do take a while but within 8 mile it should be moving and you should be getting hot air,if it's slow and drops you might have a dodgy thermostat
