C5 2.2 Hdi - Engine Warm Up Time.

[greyboy]

Dear All,

 

My 2002 2.2HDi takes 4 - 5 miles to warm up from cold; ie - for warm air to blow out of the vents and for the needle to start rising on the temp gauge. Ambient outside temp being say 5-6Deg C. Other than that it starts and runs fine with good performance and mpg. Is this normal? My old Xantia was blowing warm 1/2 mile down the road.

Was your Xantia a petrol model? It may well be a good example of the efficiency of a modern diesel engine.

Conversely I've been surprised at how quickly my Xantia Activa (2.0 petrol engine) warms up having owned only diesel engined for several years.

I'll take notes when I next take mine out, probably tomorrow. From memory it's about a mile and a half. What about the oil temp?

 

I must admit my previous 2 PSA cars (405, 406) one petrol, one diesel both had defective thermostats, which when replaced did the biz with regard to warm up.

2004 2.2 hdi, now on 20k miles. About 3 miles for the temp gauge to start reaching normal and 1 or 2 more to get there but warm air after about 1 mile. Previous petrol cars were a lot sooner than this.

Same results for me. Mine is a 2002 with 70K on the clock.

 

I would look at a possible tired thermostat that does not shut fully.

I have also had thermostats that start to open at a low temperature leading to a long warm up time and cold heater. If going to the bother of removing the old one, you may as well fit a new one.

Hi,

2.2 HDi auto (108000 2003), 2 miles (ish) before warm air from vent, dont look at the gauge, who cares as long as I am warm!! but I also drive a 23 year old Toyota and it takes just as long.

:) I have had another look at the problem and have found that if you turn off the air con the car warms up quicker (interior anyway). It will start blowing warm air in about a mile. Perhaps that is the best thing to do in cold weather, if the "auto" system has not put it off first.

My Xantia was a diesel. by the way. with a very efficient manual vent system and excellent air con.
