Hi all,

As you will see this is my first post so please forgive me if I have posted this in the wrong section!

I have got a new MGZR 2.0 TD. I love it to bits and it's the facelifted model which I'm loving. One thing that bugs me is that since I got it (1250miles ago) it seems to take about 10minutes of driving for the temp guage to move from the base and to heat up so I'm freezing for 2/3 of my journey going to work. #-o Should it take this long??! Or would there be something wrong with my heating system?

Thanks folks,
G

Hi,

Good to hear that there are some TD drivers out there! Thats the norm for the engine to warm up. Mine is the same, my dad's old TD Rover 600 (same engine as MG) was the same and my brothers MG ZT TD (BMW engine) is the exact same! I have a MK 1 (Mar 04) TD 115, with 6000 miles now. Getting faster all the time! Maybe I havent pushed it hard enough in the run-in process! How do the MK 2's drive? Any noticeable differenec to MK 1's? Good luck with the new car.

'Suckin diesel' all the way! \:D/

yep mine does the same.......
but the engine also stays warmer for longer so if you say! leave it for a couple of hours ...then go for a spin you should notice that the temp is almost instantley up to running temp............. :) :) :) :) :)




go diesel go :cool:

Technical time ..................gotta agree wiv the guys on this one diesel's take "FOREVER" to warm up ...........And the reason is ...................

A diesel engine works on "Compression" & not a "Spark" .....When the pistons reach the top it's the compression that pushes them back down & not A Fuel/air explosion....The "small" Explosion in a petrol engine causes heat so therefore a petrol engine heats up quicker ..This is also the reason for the huge amount of torque that a diesel produces.......

There Ya go Class ...Lesson over .....hope you've learnt something today !!!!!!1

Yeah mine is the same - takes about 10 mins to warm up properly. As Mr C says it also stays warm for longer too when you tun the engine for for a bit.

cast iron block - takes longer for heat to get to the water than the alloy block of the K series. Also, if you have your heater set to hot and blowing, it'll heat up slower due to the heater matrix acting like a radiator.

I had a Mk3 golf tdi previouse to my MG purchase and that took 2-3 miles at 40 to heat up. was surprised at how quickley MG's warm up.

A diesel takes longer to warm up because it is a more efficient engine than a petrol. Petrol waste a lot of energy through heat lost.

So the diesel engine wins again.

so true, but it takes about 10 minutes for any engine to fully heat up due to the consistency of modern synthetic lubricants. The temp gague is normally your coolant that heats up quickly, not the oil.

Hooded Claw, there is still an explosion. Compression ignition.

To get around this problem you can fit an extra heater. Alot of the bigger diesel cars have them as an option or standard. I am sure the ZT did.

I wimped out today and drove the car to work instead of the m/bike and was unsure whether I would have been colder on the bike.
I did 15miles very sedately and the needle didnt even reach halfway!!

but diesels also lose energy through heat loss lol,
