Factory Engine Block Heater


Recommended Posts

Posted

Has anyone successfully installed after the fact a factory engine block heater to their 1500?

Many people have. What's your question you really want to ask?

 

It goes in the driver side of block. There is a plug designed to be removed and replaced by the unit. OEM design comes with a thermostat that many remove because it won't allow the heater operate until it hits some really low temps

I did it on the ground at home, you just need an inverted 17mm hex socket to remove the freeze plug. The OEM heater element plug threads right in... I opted to let the coolant run out and lost less than a quart. The GM cord has clips attached that makes it easy to route the cord along the frame and out the front.

 

Overall it took me less than an hour including jacking up the truck. I have 4 wheel drive and got around the front drive shaft with extensions and a swivel.

Depends on the vehicle.

 

My '04 Sierra 3500 and 97 Ford F150 both start fine up to about -20 to -25C, after that, they prefer being plugged in, but they are both gas.  Diesels seem to prefer being plugged in after about -15C or so.

The reference provided was for the last gen motors. Is the 0 degrees F limit still an issue with the Ecotec3 motors? That's the question I really want to ask.

When I owned my diesel, I put my heater on a HD wall timer...unless you expect to be able to start it at any hour, having the block heater just cycle on a couple hours before you need the vehicle is really all you need...plus the electric bill won't give you sticker shock!

The early Cummins had a 600 watt heater, the later ones have a 750 watt heater. How many watts do these gasser version have?

There area about a dozen threads on this topic all going the same place. Nowhere. How about some logic?

 

1.) GM is the only one using this tech. :loser:

2.) Warm motors are more fuel efficient.

3.) Warm motors emit lower emissions. 

4.) It's code. IT does whatever you tell it to do. 

 

What's logic tells you?

 

1.) This is NOT and EPA mandate or everyone would be bound by it. 

2.) Fixable with a few lines of code

3.) There are more eco friendly reasons to use it than not to. It's not just an easy to start thing. 

4.) GM is handing people reasons to buy anything else.

5.) Stupid is as stupid does. :loser:

 

Why they wouldn't fix it. 

 

1.) Some knucklehead included it in the EPA test submission and a retest would be required. :loser:

2.) Cold starts reduce engine life by multiples.

 

:lurk:

I had the OEM Block Heater installed last week with a Marinco Black 15 Amp 125 Volt On-Board Charger Inlet and mounted it here on my A/T Grill....

    • Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.  
    • Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
    • Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."    
    • Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.  
    • Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
