Unhappy 240D no block heater

Hello all,

I am a pretty new member and i need a bit of info. I have a 1980 240D and I was looking to plug in a block heater cord. Well this is an Arkansas car now in PA. Just how hard is it to install a block heater. I just thought all 123s come with a block heater. Blows my feeble mind. Any input on this situation. I can be emailed at bluesteinm@gmail.com

Thanks
Michael

You can install a block heater IF you can get the dummy plug out.

Thats going to take some sweet tools.

I'm going to bring this thread over to diesel discussion.

To get the Plug out is going to take some work. here is a good thread of some of the effort it will take.

My signature car has no block heater and I don't give it a second thought. It starts easily in any weather I'll encounter in S. Central PA. With the proper oil and an engine in good shape, you really don't need it.

thats true, but having instant heat in the winter is sssssoooooo yummy. also its easier on your starting system.

You're right though, my tired old 617 has never not started just because it was cold as long as the battery and starter were in reasonable shape.

Also, your glow plugs have to work properly! Mine is from Los Angles, but oddly has a block heater. Number five plug is out so the glow cycle is way too short. So, last winter instead of spending $50 for the reamer, just plugged her in when I got up in the morning. Ran better than afterwards in summer. Now that winter is coming, just might do the same if I can get her back on the road. Sure miss driving her!

Two points, your sig car has 126k miles, I have one with 110k, not everyone is as fortunate as us. I don't foresee my car being quite so enthusiastic in the depths of winter when it has double the miles.

The question isn't just whether it starts, but also engine wear. Cold starts in general are the major source of wear in most motors (that are otherwise well maintained) and anything you can do to make things easier in extreme cold weather is generally a good idea.

So I always vote for some form of heat, whether a block heater or a lower rad hose heater (less effective but still better than nothing).

Also a good idea, particularly if the battery isn't new, is a battery heating pad or blanket, to ensure you get the maximum cranking ooomph on cold mornings.

Cool

hey all,

thanks for all the replies. I have about 200k on this one and I sure like to fire it right up. It was like 5 degrees here in PA one winter day and I had a brand new rebuilt engine. Did the work myself. And she did not want to kick over.

Have to start a fire under the engine on days like that.

This is not going to be fun. but I just might do the lower radiator hose heater job. That looks easy enough.

thanks again for all the input.

A Block Heater is great, as it will heat the Coolant for an easier start.

A Battery Blanket is great as it will keep it warm so it will have the most cranking AMPs it can give.
In most of these type of Threads, there is no mention of heating the Oil in the pan. Warm Oil will flow quicker to get to the critical parts of the engine. Synthetic Oil is the best in cold weather, but even if it is warmed it will flow quicker.

The most wear an engine gets is when it is first started as ZACHARAIS mentioned.

I read a book a few years ago written by an old Alaskan trucker. He wrote about several times he had to do exactly that to get his truck running.

My 300D is an original Houston car, and has no block heater. It's never failed to start due to cold weather. However, my 240D (original Iowa rustbucket) had one, and it made a big difference with the loop style glowplugs it had. The instant heat was also very nice. I work nights, so most of my early AM cold starts are at work where there's no place to plug in, so I probably won't be doing a block heater any time soon.

Battery warming

One more note... the main supplier of battery blankets seems now to be Katz, whose products by all accounts have taken a dive over the last few years. My last battery blanket from them was $25 on sale from $40 (the ones big/long enough for our batteries are expensive) and it lasted less than two months. I had one previously that died before its first winter was done.

One alternative which works about as well is to get a battery maintainer aka slow charger aka trickle charger, usually 1.5 or 2 amps, which you can permanently mount to the battery cables using ring connectors. When this is operating it warms the battery enough to help things along on cold mornings.

Schumacher makes one that is about $22 on Amazon and is designed to be mounted up against the battery (built in bracket), which I used on my last SD which was a hard winter starter. I always plug Schumacher as I've had excellent luck with their products.

You need to be carful that you get a Block Heater that has the same threads as your Engine.
Some People bought Block Heaters that Had an OD that was also too small and the Adapter Sleeves were not available.

When I was under the Car I looked and could not find a Block Heater.
Years later I found the Block Heater Cord tucked up under the front Frame.
I plugged it in and it worked.
