Block Heater

[Mainsail]

I ordered the $15 OEM one (dont need the heater, but its a good price on the cord). We'll see how it works out.

Good luck. I see a 94% ebay rating and I move on. But, it's $15 so no big loss if he sends the wrong part or never sends.

I could have used that part number about an hour before you posted it.

Sorry, gotta go to work sometime...

One thing to note is the cord length. I had hoped to go forward and have it in the grille like any of the ones I've seen in use, but the cord is way too short for that. I ended up going to the left, tucking the cord behind the metal flange just aft of the driver's side door hinge. Not ideal but it's easier not to miss it when you're getting in. The male plug isn't visible.

Which freeze plug location is normally used in HMMWVs for the block heaters?

Mine was on the left side in the 2nd hole back from the front. One more aft and it would be easier.

I guess they were already installed at the factory. There is the engine outside and no one thinks about whether this is a good or bad place later. At least from the accessibility.

But a question from my side.
- What resistance (ohms) should have the target state. And measured from one pole to ground or between the poles?
- Have you seen them also for 220V?

I have a M1043A2. 6.5NA GEP engine. No block heater. But, on the driver side there is an "X" painted on the block above a freeze plug. Not sure if that means to put it there. Or, don't put it there.

Probably has nothing to do with the casting plug, these are casting plugs, they are necessary for the casting process, the manufacturer never intended them to be used to protect the block from freezing but I suppose one day a casting plug was knocked out by the water freezing in an engine block so from then on everyone started to call them freeze plugs....
The X is likely an indication that some task had been completed during engine assembly.

Well my cord came in from ebay and it works! The connector was slightly different shape than whats on the truck (and I mean SLIGHTLY) but I was able to plug it in and it's snug. I let it sit for about 40 minutes and sure enough I can feel the engine starting to warm up!

Right along with the electric bill.

Warm HumV.... Happy HumV, CAMO
