Was late for church this morning. We jumped in the truck and I headed out quickly. Now, cold is relative. It got down to 71 degrees last night and the truck is in an unheated garage. Still, it's not up to operating speed and just like my 6.5 diesel, the Duramax and the Cummins ... it's "cold-blooded".

Got out on Rt 301 and it just was "dead". Looked down at that fuel-flow meter and my mileage at around 60 was in the mid-teens. Car in front so I went to pass, got it to 70 but it was a struggle. Fuel flow showed maybe 10 mpg. Engine would not run easily and efficiently. Did not feel comfortable with it until almost the 8 mile run to church was over. Something like that was typical for all my other diesel trucks.

My V.M. diesel does NOT make a good, short-run commuter.

That is absolutely what I found, up here after nearly 10 minutes warming up it still wasn't ready I guess which is why I got such poor gas mileage and the power wasn't their on my test drive. I thought ten minutes would have been enough but I guess not. The stripper model I drove didn't even have a temp gauge!

I definitely wouldn't have been able to put it to use during my 5 mile commute.

71 degrees at night? Sheesh. That's not cold. I wonder how it'll respond being out at night here in Colorado at -10 (and lower) temps.

I've also heard that running a load on a cold diesel engine is the kiss of death.

My truck has been completely different than yours. 1st day I got it it was 15 all night 18 at start up. Within 3 mins it was operating perect. And its been 35/45 every night since I picked it up here and it has been fully functional from them min I hit the road no worm up other then start it buckle up both kids then go.

I would also never call 71 cold haha but I live in Oklahoma where its 15 one night 75 next day at lunch with snow ice and tornados all in a 24 hour window.

But with out a doubt this truck heats up way faster then my 11 6.7 or 05 5.9 cummins every did.

This winter we got down to -20 quite a few nights/mornings. My 2013 passat tdi (which doesn't even have block heater option in NA, only canada) started just fine in that weather. I know this truck is a 6 cylinder vs the 4 passat, but I elected not to get the block heater on it assuming it will do fine as my experience with other newer diesels are just fine in the cold.

So 1, don't scare me saying it doesn't run good cold. And 2 please refrain from calling 71 cold. 35 degrees here near Chicago has been tshirt weather and borderline hot feeling.

On a side note, I hope it gets warmer down there by next week. We are driving down to Disney World.

I believe the cold temp was mostly in relation to the condition of the engine. And while you want to be a pedantic ass, Canada is in NA, it might not have been a US option on your Passat. As for not getting the heater on a diesel in Illinois???? Might be winner for worst thing you could have selected, should be fun come winter if it's parked outside. And that opinion comes from a guy who operates V6 diesels in GA and knows how tough they are to crank at 30 without one, never mind the fun that was starting my truck at 12 degrees. And the fact that Ford added at dealer cost the cold weather kits to every F250/350 they were selling when my dad was looking in Minn to protect themselves from warranty claims, $80 bucks dealer cost was cheaper than the time to argue about it with a pissed off customer.

First, you know what I meant re US not NA. So your saying it's a mistake not having the block heaters on any diesel or just larger diesels like this 6 cyl? Cause like I said, the passat did just fine.

And didn't mean to come off as an ass, but it's been a long winter

I once owned a Ford Escort with a Mazda sourced diesel engine in it. At the time I was living in MI. It did not have an engine block heater in it. The thing shook like hell when it was cold in the winter but always started. It came without a plug-in heater. It wasn't just a dog for acceleration, it was two chihuahuas pulling a piano fast! I was a lot rougher until it got warm but still got me down the road. Since I have not owned a diesel since then, I am glad this topic was brought up. I hope the RAM does not have a problem in this area since I did not order this with a plug-in. I figured that my past experience and my residence now being in the Houston, TX area would eliminate any need.

Time will of course tell.

Work truck has a block heater and I live in Houston. It's a cheap addition, every ford truck has the block heater installed you just have to get the cord to plug it in which mine does.

My 2500 CTD has a block heater, and if I plug it in at night, no matter how cold it is, it starts up like I just got out of it.

Without the block heater, on a typically 30 degree night (this time of year), it's starting to blow a little bit of heat after about 4 miles or so.

I'd highly recommend a block heater, in fact, it's too bad it's an option on this truck. It should be standard, IMHO.

Can't find the 110 volt cord for the block heater. My friend and I spent about a half hour or more looking top and bottom, left and right side. I did order and paid for the block heater, shows up on the window sticker. Does anyone know where to look for the cord? I let my truck idle for a couple of minutes before pulling out of the driveway. Seems to run fine.

Cut and pasted out of Ram 1500 diesel owners manual,ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms engine coolant and permits quicker starts in cold weather. Connect the heater cord to a ground-fault interrupter protected 110–115 Volt AC electrical outlet with a grounded, three-wire exten- sion cord.
Its use is recommended for environments that routinely fall below -10°F (-23°C). It should be used when the vehicle has not been running for long periods of time and should be plugged in two hours prior to start. Its use is required for cold starts with temperatures under -20°F (-28°C).
To ensure reliable starting at these temperatures, use of an externally powered electric engine block heater (avail- able from your authorized dealer) is recommended.

Look at the upper passenger corner of the grill.

My duramax has a block heater. 200,000 miles and its still coiled up from the factory. I made grill inserts out of black Plexiglas. I put them in in the winter. Like a cold weather bra but looks better. Helps a lot with warm up. I can run them up about 55f

Engine block heaters are for starting. They take the chill off of things but do not bring the engine up to operating temperature. When It was going on I looked at oil temperatures in the 130 degree range. Coolant was also low in temperature say 120 or so. Until things get into the high hundreds the engine is flat out sluggish with fuel mileage and wear probably high.

As for Disney World, bring lots and lots of cash. Floridians avoid Orlando and that Disney circus. In fact, if Florida needed an enema, they would put it in Orlando.

I have the same problem with my F250 I'm looking at the highway from my porch so in the morning it's sketchy going to work. I have about 1/2-3/4 mile of access road and then I'm on the highway. Eve in high idle it doesn't warm up very fast, but once on the highway and going 60+ it takes it 2 miles to liven up. I try my damnedest to keep it out of the boost till then but even getting on the access road from the house will push 10lbs.

I used to plug my TDi in every morning from Dec. - Mar. when I used to commute, it made a noticeable difference in fuel economy and the heater would be blowing warm in a few minutes as opposed to the 20 minutes it would take without plugging it in.

I think block heaters and heated seats should be standard in a diesel, well at least here in Canada :)

The early Duramax's used to come equipped with snap on grill covers for the winter. I'm not sure if they continued with the offering.

You wanna see cold!?! My front porch last Jan in downtown Fairbanks Alaska!



Lots of diesels up here but they, like all rigs, are winterized with block heater(s), battery, oil pan and tranny heaters. Cold fronts too. I use a piece of cardboard on the Toyota. Diesel pickups they run up north on the slope they never turn em off. Most diesels have a fast idle setup. Used to be an aftermarket deal. Not sure about these new rigs. When I sold Fords back in the late 80's and early 90's, we always told people diesels like to run hot and hard. Lots of people run HD diesel trucks here like cars and do the same, leave em running all the time. I test drove a Jeep EcoDiesel last month. I think it was about 15 above that day. We let it run about 5 mins and took off. I was impressed with the performance of it.

The only info I could find on Ram cold weather testing was a video they do that shows testing at 20 below in Minnesota I think it is. 20 below?? are you kidding me! We are happy when it warms up to 20 below in the winter! I'd like to know how this DEF setup will do. I guess other oil burners have it now so it must work, at least some of the time!
