some general questions about the crd

So I am looking for an upgrade ffrom my current 05 with the 3.7. I had always thought the Hemi was the way to go but in my travels through the various dealerships and used car lots i have found alot of the 07 and 08 crd models. It got me thinking that maybe i should consider one. One of the reasons i was thinking this is that medium duty towing is something i would like to do (4500-5500 pounds) However i do have a few concerns considering the year round duty it will see. Hoping you guys can comment on the following:

1) I know it's not a v-8 but is the performance acceptable,keeping in mind i drive the 3.7 currently??

2)Is there any tuners available for noticeably better power without damage to the engine?

3) cold weather--it will be a daily driver in the winter and will see some very cold temps up here in Canada. Do i need to give it a long idling time for warm up? I know a diesel needs more than a gas but how long on a good cold day (say -25-30 celcius, works out about -20 F) and how long does it take until it's blowing hot air? I have a short drive to work (10-15 minutes) and would be very unhappy if it doesn't warm up until i get there,lol

4) why would i see so many of these on used car lots all of a sudden? Lots of owners getting rid of them for some reason? mileage varies from 40,000km's to 70,000 kms. seems low for a diesel.

Any other things/perks good or bad i should know before considering further?

Thanks

2)Is there any tuners available for noticeably better power without damage to the engine?Yes

I have a short drive to work (10-15 minutes) and would be very unhappy if it doesn't warm up until i get there,lol With proper winter fuel, there should be no problem. No Idling time required.That is about the time, with engine block heater sooner

4) why would i see so many of these on used car lots all of a sudden? Lots of owners getting rid of them for some reason? mileage varies from 40,000km's to 70,000 kms. seems low for a diesel. No reason realy except buying now model.

Any other things/perks good or bad i should know before considering further? Regular service, good motor oil, good fuel (very low sulphur),



Thanks

Re: some general questions about the crd

Having driven the Hemi and owned a CRD I'd stick with the CRD. Driving diesel gives a different feel than gas but once you adapt it's great. Towing is the same for both but you'll get noticeably better mileage out of the CRD. The mileage is what really sets the two apart.

I live in the NWT and never had issues with the CRD in the cold. They are equipped with electric ceramic heaters so warm air comes on pretty quickly. I usually start it up and let it idle 1-2 minutes before I go for oil pressure and such, within a few minutes it's blowing warm air. Never used any additives. I use the block heater past -15*C but I have had it start down to -30*C without the block heater, though I'd definitely avoid doing that more than once or twice. Try to avoid excessive idling.

Make sure you use the right oil (meets MB 229.51 specs i.e Mobile1 5W-40 ESP Formula) and try to get diesel from a station that sees a lot of traffic so fuel is fresh. Work the engine every once and a while, if you'll be towing a load in the 5000lb range every once and a while that should do the trick.

Not that I think it would happen,but whatever you do,Don't blow up that Mercedes 3.0L. You don't want to buy a new motor. I was bored at work the other day so I checked the price.List price for that engine is over $35,000!!!

But what you have to do to blow the motor. Just give it what is required and drive it. Those engines are running over 500 000 km without problems. With proper care off course.

Re: some general questions about the crd

Exactly. I don't really think anyone is gonna blow one up. But if they did. I was just commenting beacause of the cost of the engine.
