if you want to bring the temps up quicker try altering the water/anti-freeze mix
So you would say the thermostat is working fine? As it took my Civic 2 minutes to reach operating temp, but then again that was an aluminium petrol engine that drank petrol, while the DTi engine is cast iron - more dense metal to warm up. I had an eye on the clock today - took 17 mins for the engine to reach normal temp - 15 mins city driving, and then 2 mins dual carriageway, ambient temperature was about 16 degrees C. I probably will test the thermostat to make double sure it's OK anyway.

I remember several years back in my Nova, the fan thermostat switch failed on the hottest day of the year (30 degrees C IIRC), and I was stuck in a 2 hour tailback for a mile. The engine kept overheating and I had to turn the blower fan on full. I nearly got dehydrated - I didn't have any water with me! I was wishing I had a paperclip with me on that day, I would have been able to short out the thermostat plug.

Thanks for advice!
