Hi all - what kind of work am I in for in putting a block heater in a
240D? It never had one before. Is there an existing port for it
already? or do I knock-out a freeze plug (did that on my Jetta 'long
time ago)? Screw-in? Clamp-in? Et cetera. Any help/tips will be
greatly appreciated! :)
Remove block's iron drain plug on its right side, near starter. This old
plug will probably be very difficult to remove after twenty years. Start
with penetrating oil for a week or so before attacking it.
Suggest you first get the plug loose THEN buy the heater.
Re: REQ: '83 240D block heater tips
Oh? It mounts in the drain plug? I'd thought it was in a port
further-up the side of the block (obviously I haven't looked yet). NOW
I've got something to go down and look for. Thanks.
i have never tried one but before skinning your knuckles & breaking
i have heard of people using heated lower radiator hoses & battery pads.
i have been spoiled and have had block heaters in all my 3 diesels !
the case, minus a few cans!
My apologies for combining threads; it seemed like a good idea...
I just looked down the passenger side of the block from above - PLEASE
tell me it's the hex-head bolt near the starter and NOT that (approx)
1-1/2" dia. recessed one! (nem'mine - I already know the answer) I'm
assuming it IS a right-hand thread, and it looks like I'll have to drop
the starter to get at it clearly, right? :\
<rant> WHYINHELL DO THEY FIGURE THEY NEED SUCH A BIG, STRANGE PLUG JUST
TO DRAIN COOLANT??? </rant>
Any leads on where I can get the socket? Performance Products has the
heater for $44 right now and I think their Christmas sale is still
This car's always been a 'summer baby' only but, sadly, that's no
longer possible and now I find myself needing to get this done now
rather than during the summer.. :( I'd heard about heated hoses/etc.
too but can't seem to find those hoses in any of the catalogs...
I've done a number of these. The plug is a hex socket, 19mm or 3/4 inch. You
will need a 3/4 inch drive T handle, 3/4 drive 19mm hex key, or 19 mm socket
with a short piece of 19mm hex key ( this is what I use), a pipe about 4
feet long to slip over the T handle, and a pencil to hold between your teeth
while you attempt to loosen the plug. Removing the plug before buying the
heater, as another suggested, is excellent advice. The plug might not come
out. And take care that the extension pipe doesn't make a dent in the hood
if or when the plug comes loose.
Yeah, it was really hard for me too. you MUST get the proper tools, I had to
buy one of those sockets. Then I had a huge breaker bar, and on top of that
I had a long peice of pipe that I had to use, then me and another 6'4 guy
both were trying to break it loose. We finally did it, (this was a summer
job) but we ran the engine a good long time to warm it up, then we actually
(I don't know if this helped) got a propane torch and for about 5 minutes I
heated up the area around the plug, then I got out from under the car and we
started to try to unscrew the plug, and then *BANG!* it broke, then it's
smooth sailing from there. but it's WORTH IT! I'm here in utah, my car's
pluged in now, and it's 10-20F degrees cold here @ night, and whenever I
turn it on, it's like 40C already, no hicups, no coughs. I should post how
I did this in mbz.org sometime soon.
