OM617 Block heater question for electrical gurus - Page 2 - PeachParts Mercedes-Benz Forum

Army,
Your motor after the rebuild will be that tight & good on compression that it wont need a block heater in your life time. If on the one very cold morning when the car has been not used for a week, has been out in the weather & is long over due for the valves being adjusted. Do as I have done, borrow the Mrs's hair dryer, pop the air cleaner lid & have hot air going down the throat while you crank it. It worked every time for me with my old worn out 300D.

Great bit of information funola - if you don't mind me asking do you know that from experience, or is that in the FSM, or is that posted somewhere on this forum or the web? I ask as it may lead to a part number or more information... cheers!

I completely agree layback40 - but you've forced my hand - now I have to admit that I'm a sick man:- I think I'm turning into Mercedes gadget man...

If another Mercedes arrives on my driveway it could be D I V O R C E - but if the existing one just gets leather W126 steering wheels and block heaters it puts a smile on my face and her indoors doesn't appreciate or even notice such things!

All you need to know is ohms law.
If you know 2 parameters, power and voltage, you can calculate the 3rd parameter, resistance.

Here's a convenient ohms law calculator.

Ah ha so that's how you got it - I see now - I didn't know the power. I'm assuming that 400W is standard for both sides of the water?

Update - just to let you all know. A block heater is still available from the dealer that runs on 220V. But it costs in excess of 500 euros including Dutch purchase taxes... oh well...

Army,
if you are still looking for a proper 230V block heater for way less than 500 contact me. They sell 'em at the stores here for way cheaper than that and we can probably work out a simple payment and shipping deal

(and I am talking Calix or Defa brand). Best regards, Vic from Finland.

My 1982 123 300d has a block heater, but today it started well without the block heater plugged in at about 20 degrees after I shoveled it out from the blizzard that we just endured, in New Hampshire.
I agree that it's nicer to start out in the car after it has been plugged in, but not necessary in this climate or anything milder.

For those (few) of you who are looking for a 220V block heater for an OM617 - here is some information courtesy of the information provided by Johtotahti:-

DEFA

411214 cable
411265 heater

CALIX

1777302 heater 550W
1762461 cable set
1760015 Branch cable set

Alternative:-

1788701 heater 550W

I can get good prices for the DEFA model in Germany - and a silly price for Calix in Holland...
