Warming Up

With the sudden drop in temperature I'm finding the car very slow to warm up with the gauge taking at least 10 minutes to even register anything.

I know diesels do take longer to get warm but anybody ever had any issues with the thermostats? Do they have any problems with not closing fully?
 
Ran the diagnostic this morning to watch the actual temperature and saw the following:

After 5 mins of idling and 10 mins of gentle driving - 52 degrees
After 5 mins of idling and 20 mins of gentle driving - 60 degrees

Peaked at 76 degrees after a few hills.

Think I have a thermostat problem!

Anybody replaced one? Is it easy? fiddly? nightmare?
 
Are you talking about 10mins driving or 10 minutes idling?
Mine takes some time to warm fully as well, this morning @ 0°C it took 10 miles to come to running temperature on the gauge.
The thermal efficiency of diesels is a lot higher than petrol cars and this is why the aircon runs as a heatpump when the engine is <70°C to help the engine warm faster rather than diverting warm water to heat the car interior.
 
It was 5 mins idling and then 10 mins driving. My aircon is currently broken so not getting much warm air in the car. Thank god for heated seats !!

I realise diesels do take longer to warm up but I feel mine is taking too long - only 75 degrees after 25 mins!
 
76 degrees is correct operating temperature for this engine. What was the ambient temperature? If it was very cold outside then this is probably just normal.
 
Ambient was -2 so yes was cold. Was expecting the thermostat to be more in the 80 to 85 region.

Will see how it goes then.
 
On the diesel car, if ambient temperature is <5C AND engine temperature <70C then the A/C runs the evaporator as a heat source i.e. the system becomes a heat pump reversed from normal direction of heat transfer

But, your A/C is broken, so as a heat pump it won't be transfering heat in any direction
 
Indeed but the Timing Chains were the more important thing!

Need to find a right size belt to take the compressor out of the circuit so I can remove it and look to get it repaired / replaced.
 
I've had the same notion for my Accord (2.4) because the compressor clutch stopped pulling in on my car a few months back, it's a good idea to be able to remove the compressor. I think I saw someone had a shorter belt to do this but I can't remember which Accord or where I saw it.

(note that the 2.4 petrol warms up quicker than the 2.2 diesel so no "heat pump" setup, hence compressor not required to work for heating in winter)
 
from the other new thread you got a shorter belt to size quite quickly, or did you use the wife's nylons LOL
 
so it's PK1425 for the 2.2 , note that mwahab used a PK1385 on a 2.0 (non EPS I think) which should be same for the 2.4.
I might do the same thing on my 2.4 as the compressor has stopped working on my 2.4
