1984 300SD block heater

[jack avant]

I just finished installing a new block heater. I removed the breather, the breather brackets, and the heat shield bolted to the manifold. It was a two man job, but with a 46mm socket and a long pullhandle it came right out. Just thought I would share this because I was dreading the job.

Thanks I will be dreading it shortly, after the weather warms up a little and I get the car indoors.

This proves that not all diesels came with block heaters.

I believe it is pretty well documented on this site that not all MBs came with block heaters. I also believe that all OM603s did come with block heaters. In every block heater thread I've perused in the last 5 years, anyone with an OM603 was able to find a block heater installed once the location was described to them. When purchased new there was a coupon that came with the car to have the cord hooked up to the heater for free for one year.


My car spent its life in Seattle and did not have the cord attached when I bought it. I removed the black cap and installed the cord.

DIY difficulty level 1. One hour tops depending on how many beers you have during the install. Of course YRMV if you are installing it outside in 0 degree temperatures.

My OM603 have a block heater, but it is NOT from the factory, it is retrofitted when the car came to Norway in 1997. Euro spec mercedes never have block heaters from factory that I know of, but the dealers can supply it at extra cost.

Ditch the block heater and install webasto in stead. No need for external power, need only 15 minutes for warm engine, or 20-40 minutes for warm engine + interior :-)

Again, US delivery OM603s came with a block heater from the factory.

my euro TD did not come with a block heater, nor did several of the cars I have. TOTALLY amazed you got the plug out so easily! Congratulations! I've read on here the thread about the torch and the 6' cheater, and the MASSIVE amount of strength needed to remove these! maybe the 84 used some neversieze or something on them...

Do you know the part number for the block heater?

Here is the one for the OM606. I believe they are all the same, but have not verified that.

Item Number MSRP
6062000096 $135.00

would be nice.

I have to renew mine, as the crappy, norwegian produced "defa" crap that all Norwegians for some reason think is so great, really isn't that great.

So this is an original block heater, produced by mercedes-benz?

do you know how many watt?

This is probably 110V, so I cannot use it anyway, but maybe there exist a 220V version.

I think the original one in my car is 400 watts.

MB must have made one for Europe that is 240V. They do sell their cars in Scandinavia, correct?
