Title: Cooling , 2.2 diesel on a 03 plate
Post by: ARGYLE47 on 08 February 2012, 17:38:08
Hi guys, not really a peoblem just need my mind put at rest. This week with temperatures around -4  on my drive to work i noticed the engine temp takes a long time to start to climb, it's about a 15 min drive to work and hot air soon comes out of the vents, but engine temp is barely registuring, do you think a tempory fix would to put a bit of card board in front of the radiator, cheers

No point in my opinion, the water in the rad isn't going round the engine so it doesn't matter what temp it's at. You will probably find it's the thermostat sticking, and (if the 2.2 has a HBV) it will use the limited hot water to warm your heater.

Sounds like a failed thermostat to me too. Best to fix it properly as running cool will wear the engine faster and use more fuel in the long run. There's no reason why a modern car should behave any differently in cold weather (other than a failed thermostat).

DTi's are slow to start registering any temp on the dashboard gauge in the current cold weather. Mine takes a good ten minutes or so.

I agree with VXL V6, they are slow to warm, which is probably why they are fitted with a diesel powered micro central heating boiler
 (eberspacher D3W) that heats the coolant when ambient temp is below about 5C. 

After  11 years my diesel heater has just failed and I have noticed that the car takes longer to warm through than when it was working. These things are expensive to replace  and most ( including me) simply bypass them when they leak coolant.

Have a look under the drivers side front wing and see if you can spot a silvery coloured thingee with a miniature exhaust pipe in front of the wheel. If not, it has been removed and by passed.
