Real Cold Start

It was 6 degrees out this morning. Went to start the truck early so the drive to church would be warmer. Boy what a chore. The truck sounded like it was in mud lugging at 500 RPMs. It fired but sounded real pissed for bothering it in the cold. Oil change is due so maybe this will help out some.

Dug out the block heater wires. They were still in factory wrap never used till now. Rather than put the truck thru the lugging I figure a lil warm up on the real cold days will keep it running a few more hours or years.

I'd be mad too if you tried to get me started at 6! We just had a cold front roll through. Dropped it from the mid 80 down into the 60s - time to break out the electric blanket! I've got a lot of respect for you guys. I don't mind telling you I'd die my first winter where you live.

Oh my 6F...... really?
Try the 6 good months in Alaska where 6F is a heat wave.
Light weight oil will help along with a good set of glow plugs and the relay if the truck has one.
Might also be time for a bra on the front of the truck.
A little trick that I learned while I was dealing with glow plugs that where on the way out and an alternator that was question able .. double cycle the plugs. ie wait the two minutes and then wait another 2 minutes and the van would start up.
Now that the temps are getting below 15F I still do the double cycle and she starts up no problem,, that and the light weight oil.
Now when it gets below 0F I will plug it in for about 90 minutes and it is even happier and I can do the single cycle on the plugs.

Yes I know folks living near Tok (??) and they never turn off the car for fear the fuel freezes or something silly.

6 is cold anywhere. The only problem seems to be slow cranking. Batteries are new but an off brand, oil is old and due for a change. I believe the only problem is cold cranking slow. I plan to clean the connections to ensure a better ground and check conditions of cables. New batteries on the list when I can afford quality. I just bought a tool shop so money is tight.

Make sure that the Alternator is in top shape, a weak alternator is death too the batteries, and in cool or cold weather it can be the difference between getting started and finding a charger to charge the batteries to get going.
Having an alternator go out while on the road is not a good thing either, had that happen years ago 100 miles short of Fairbanks and it was -35F that night.

Fresh oil is another good idea..

Life with the cold like here in Alaska , even in south central or just south of Anchorage is some thing that either one learns to deal with and roll with or one moves to a warmer area..
Cold does have away of showing one the faults of the rig and what needs to be fixed.
Another little trick is one of the heating pads, about a 6x6 on the oil pan. It can help when plugging in the truck when it is well below freezing in getting oil temp up for better flow through the engine and the HPOP..

Well, again - I'm no expert on cold weather but here are a couple of ideas. "You'se guys" who deal with this feel free to shoot them down. Would a trickle charger permanently installed be a good idea? They draw next to no current and would keep the batteries topped off overnight. Do they make battery warmers? If one was to wire such a critter into the same plug (I assume you all have the Marinco mod) as the block heater and both were run for a couple of hours before starting - theoretically, you'd have more starting amperage.

OK - I went and looked. We're going to call this the RT mod.

Kat's 22200 80 Watt 36" Battery Thermal Wrap : Amazon.com : Automotive Kat's 22200 80 Watt 36" Battery Thermal Wrap : Amazon.com : Automotive

Two of these suckers in place of that cheesy wrap that came with the truck. Wire them both into the back of your Marinco mod along with your block heater - plugged into a timer that runs for two hours before starting.

All great ideas. Best note was the cold brings out the faults. I now know my batteries are weak but will work. Oil needs changing but it is due anyways. Alt and batteries checked good when it was warm it is just the cold putting extra load on the system. With great connections and fresh strong batteries I know there will be no problems. Most important at 6 degrees I even did not want to be outside. The block heater on a timer in the mornings will help out alot. Heater pads on the battery and oil pan would be great if it was always cold like with the durable folks in Alaska. For me the garage is soon to be empty and the truck will have a warmer place to park. The block heater will be enough for now.

I also used to use a 60 watt light sitting on the floor under the oilpan. I used this with dogs and puppies before and it also worked well to give light heat to the truck. It did not work as well as the block heater but it was a lot cheaper. Inside the garage it works great on my lil 1.6TD VW motor.

The trickle charger is one of the items that I have wired in and can be used for times that the temps are well below the 0 F .
But having a fully working Alternator, good batteries, 5/40 oil, good anti-freeze for low temps, good glow plugs should be able to deal with temps above 10F.
Getting blow some of the things that will help from what I have found.
Oil pan heater, block heater, front cover, trickle charger.
I have gone round with a few about what should be used, and what I am using is from years of having to deal with the cold, and not what some engineer who deals with the cold for maybe a month state side says is in the book.

I just did a 5w-40 oil change.

One year, through a hookup, I got a 5 gallon bucket of caterpillar 0w-30 Arctic DEO for free.

That alone changed the way the truck started up, but at $300 or more per bucket, not a solution for everyone unless you plan on making it through the entire winter without an oil change.

Check your wiring harness: Chaffed wiring at driver's valve cover.

Keep everyone (and yourself) updated:7.3 mileage and repair thread

If you insist on throwing parts at your truck to fix the problem, go big--don't forget the driver's side frame rail.

If your ICP connector has oil in it, change it. Don't argue, just change it. Don't check other things first, just change it.
