1990 560SEC, radiator
Just replaced the Behr OEM replacement radiator after only three years in service. The original lasted 13 years. Was leaking around the left and right ends of the plastic tank. Kept the old one with the idea of fabricating another out of all metal (brass/bronze) upper and lower tanks, and the radiator. Has anyone ever heard of anyone doing this?
BTW, the rattling and squeaking behind the dash seemed to come from the two rotating AC vents in the middle above the console. Seems like a few judicious squirts of silicone spray will silence this annoying sound.
Happy cruising :-)

Tad:

I cut the other posts to simplify the read.

Oil pressure is just fine as you describe it. Radio needs to be
operational to operate the antenna. Radio imposes +12 VDC to the
antenna. Does your 82 have an Antenna switch for mast height in the
console? I'd pull the radio and check to see if the harness at rear is
plugged in and getting power. If you choose to keep the original radio
there is a source that handles the Becker head unit and associated amps
and fader repairs. If you choose to replace with an aftermarket, this
list will jump to life with all sorts of recommendations.

I'd pull the instrument cluster (ic) and check that the harnesses are
plugged in. Then I'd check the two ground paths directly behind the
ic. The clock is the first and easiest power source to check back
there. It's a single lead providing continuous +12vdc that attaches to
a spade lug on the clock segment. Check voltage between this lead and
one of the ground points. See what you get before working the ic repairs.

Engine. If it's still a single chain engine, I'd expect to spend some
serious money doing the dual chain conversion where it is equally likely
the cam shafts and rockers have seen better days. If on the other hand
the dual chain conversion has been done I'd next inspect the chain rails
and tips of the sprockets. Look for cracked or chipped rails. Tips of
sprockets should not have sharp pointed edges, should be smooth with
some meat at the tips to round them out. Then inspect the cams lobes
for galling. If the cams are galled the rockers are galled as well
(rockers not easily viewed without light and mirror). I have wet lapped
a few cam lobes and replaced the respective rockers to eliminate a miss
and a tick but, once the metals have started to go (scoring/galling) you
are looking at more machine work or the need to replace the cams (about
$800 each) plus the rockers (short money). Again, I'd hold up on doing
too much until you see the history on that engine from the dealer.

Washer pump, if you pull the pump to inspect the inlet, which may be
plugged with sediment, you will instantly need a new seal/grommet for
the reservoir where the pump is seated. So, I'd have one or two
(headlamp washer line if equipped) ready when you do this fix. You'll
need to pull the battery and that's a good time to repair the batt tray
and inspect underneath for corrosion or damage to the sway bar fitting
that sits under the tray. New tray is <$20US.

Worse case, is replace the engine with a 500 motor for more horse power
(380 US is sadly lacking (160+- hp)) and get a longer lasting motor with
less dollars outlay if you do the swap to a 500 (US 184 hp) IMHO.
Preference on a 500 is the euro spec (240hp) if you can find one.

I wouldn't mind keeping the existing radio, kinda looks cool with all the
buttons on it. :)
I assume that to pull the radio I will have to remove some panels? I really
need to get a book on this car. From what it sounds like it has a separate
amp for the speakers... I wouldn't mind bypassing the entire radio and just
attach my ipod directly to the amp. Is that possible? Don't really need the
radio, although I should fix it sometime. I guess the ultimate fix for me
would be a small hidden audio jack somewhere that when plugged in, would
override the radio and allow me to play mp3s directly to the amp. Quality
would be better too.
Am I way out in left field here with the way I understand how the audio
system works?

Well, I can hear the clock ticking, it just doesnt move very quickly, or at
all.

Still waiting on a reply from the dealer, I am hoping all this has been
done.

How much does one of those engines cost normally? I assume its higher than
rebuilding/fixing up the old engine. But then, I would get more HP, which
cant hurt anything but gas mileage. :)

Tad;

Another opinion........

The early 380 engines supplied to N. America in the SE, SEL and SEC were all with single timing chains. Many were converted under a warrantee or limited warrantee, but it was essentially a "secret" warrantee. M-B replaced lots of complete engines that suffered premature chain failures.

But having one of these engines doesn't mean they are scrap. To check, remove one valve cover. If yours is a single chain, install a new one and note that it should be replaced again every 30,000 miles to increase your chances of getting lots of service. Let's face it, the engine is now 25 years old so it couldn't have been all THAT bad.

To convert the engine now would likely be foolish. It isn't just changing the chain. You must change all the sprockets and the front cover. Some parts can be had used from a later 380, but it is still a big expensive job. And Dick is right, if you are planning to do that, you'd want to renew everything questionable.

Take a cover off and confirm what you have. Likely for comfort, you should replace whichever chain and guides there anyway. Then enjoy your 380SEC. And forget about beating the greasers and their crappy racing-ricers off the line, cause they'll beat the 500 too.

You're driving a 25 year old classic! -Bellamy

- Yes, and its the same price as a timing chain change.

- Yes, the radio send a signal through the antenna switch. Without this signal the antenna won't work.

Windshield washer fluid is not coming out.
- Check all the hoses and blow through them with compressed air if necessary.

I just purchased a 1982 380SEC, and it
runs great. There
are a few little issues that I'd like to get fix.



The first thing is the locks. I know they are vacuum
based, but other
than that I dont know much. Basically what happens is that when I lock
the drivers door, either with the key or the lock itself, I hear the
pump run, and all they all lock, but then the passenger/trunk/fuel
unlock, and then they all lock. It never actually stops doing that (it
did it for about 10 time before I decided enough was enough and pulled
the drivers side lock back up to stop the endless lock/unlock cycle).
Now this car did have a dead battery for a while, so perhaps some
sensor needs to be reset? I am not sure.
You'll need to read up on the simple 3-wire vacuum pump on your 82 SEC
in the MB manual. Pull the fuse for now from the engine compartment
fuse box so you do not burn out that expensive pump in the trunk spare
tire well. Pick up a Mighty Vac ($30) and start with the vac line at
the pump and work your way forward from trunk lid to gas cap to
passenger door to driver's door to see if there is a slow leak or a
break in the vac line. I've seen many breaks at the point where the
line passes through the door hing rubber seal. Don't pump pressure
above 10 inches on the Mighy Vac when testing





Purchased a mighty vac today, I
will test the vacuum in the next few days. I didnt pull the fuse, I
unplugged the pump in the back. Is that bad or should I go ahead and
pull the fuse as well?
So long as the pump is not powered you are all set.



Great.



The car idles low, and lags roughly for a second before
the car
accelerates. While idling, it also surges, almost like its idling so
low than it revs itself to keep it from stalling. The previous owner
said that the injectors were dirty from sitting for so long (probably
sat for a year or 2, then he drove it everyday to work for a few months
and then parked it again). He took it to our local MB dealership and
also to a regular car shop and they said that it just needs to be run,
with some injector cleaner in it. They recommended that if its
'working' then dont touch the injection system. Is that all that it
really needs, or should I take it in myself and have it checked? Is
there anything I can check myself? Well, you can start with 1 can
of BG-44K ($30 or less at MB
dealer) and see if the performance improves. If not, take it back the
the MB dealership for a proepr run through or you will have to become
somewhat expert in short order to do all that is required to diagnose
and fix the engine and it's systems yourself.





I have already put a standard
bottle of injector cleaner (Tekron brand I think). This morning its not
doing the lag when revving the engine, so it already seems to be
improving. The engine will start doing the surging after about 2-3 min
of running from a cold-start, but it doesn't seem as bad. Whats the
idle rpm supposed to be? Perhaps its too low?
Park or Neutral and coolant temp <42 C 750 rpm minimium; >42
C 500 rpm minimum for 116 81/82 380 US.



Thats what I am seeing for my RPMs, hopefully it will clear up on its own.





A gas gauge does not work, where should I
look first to fix that (makes
me worry that I will run out of gas at some point)

The radio/antenna does not work (I really want to replace the radio
with something more modern, and if I want to upgrade in the future,
having a working antenna would be nice)

The sunroof sometimes works (prev owner stated that alot
of the
electrical problems are just caused by poor contacts on the switches,
and opening the dash and cleaning up the contacts on the switches would
help) (hah) Start by ordering up a complete fuse replacement kit
($10) and
replace every fuse in the fuse box. See what is then fixed and report
back. I would not dive into much of anything until the fuses are
replaced.



Just replaced all the fuses,
nearly ran autozone out of those types of fuses. Should I find a fuse
replacement kit and do it with those, or did I effectively do the same
thing by buying standard fuses?
Copper tipped fuses replaced every 10 years of the correct value
and you should be all set. Clean any fuse holders that were pitted or
burnt with a qtip and sandpaper.

Fuel gauge doesnt seem to be
working yet either. Where is that sensor located? I suspect the car sat
without fuel in the tank for a period of time, and perhaps the sensor
rusted or froze up. The sender is in the fuel tank behind the rear
bucket seat driver's side. Probably need a new sender and seal if as
you say the car was let to sit with anything less than a full tank of
fuel.


I guess I will have to get in there and take a look at it.




Odometer does not work, title already states that its 'not
actual', but
can I get that fixed? Fuses first and yes the speedo can be
repaired if needed.





Since I have never had a MB before, this will be a great
way for me to
get familiar with how these cars are put together. I just replaced a
few lights and the sealed beams (cant wait for euro lights later on,
what a PAIN to replace those sealed beams), so now I can get it
registered and on the road. I'd suggest you have someone confirm
that the timing chain on the
380 motor has been converted to a dual chain before spending any $ on
the SEC. You need to get a copy of the MB Cd-Rom for service on your
SEC ($20-40 as a guess).





I emailed the local MB dealership,
where it was supposedly taken regularly for all its maintenance. Would
the dealership automatically upgrade it to dual chain if they replaced
the timing chain? I'd sure hope so!
The engine is junk if it's not dual chain. And then try and obtain the
mileage on the dual row chain, tensioners and guide rails since it was
last done. See what the dealership says.


If its not, can I still get it converted to dual chain? Or is that too costly/not possible?








Thanks for any replies!

You mention odometer not working. Does everything else on the
instrument cluster work except fuel guage? Clock, tach, speedo all
okay???

Clock, fuel gauge, and odometer does not work. Oil pressure goes past 3 when the engine is revving but it otherwise stays in the middle, not sure if thats normal.


A few other issues...
Antenna does not work, does the radio need to be operational for the antenna to do anything?

... Radio does not work, where should I start looking to put a new one in?
Windshield washer fluid is not coming out. I hear it running, and theres fluid in the tube but its not moving. I assume its clogged or something. The pump sounds like its running dry, although the tank is almost full.


Thanks for the replys.

Hi James: You should be able to check the euro epc site for the correct part # assigned by MB for your euro 500SEC. I believe your idle control amp part # is 002 545 40 32 from the source that I checked. There is a difference in the US part # for the 500 and this is in the 40 being replaced with a 33 as is the case on my 83 380 US SEC which is interchangeable with a US 500.

I just bought about 2 month ago a car cover for my 560 SEC. I went to the mercedes dealer.
I paid $208. It has the MB star on the front and the word mercedes on the left rear, but it is made by Noah.
Well made 4 layer cover, soft and strong. I think when you by this Noah cover from somebody else you might find a lower price.

Yeah I already have the new valve cover so will not need to buy that. I
also already put it on for the time being so there will be no dust going
inside the motor. I guess my question is if my pistons smashed the valves
is there going to be obvious damage to the heads like rockers laying
around, or bent, snaped cams? Another question was how likely is it when
your chain jumps that the piston will meet the valve? Or can everything
appear normal, so I will need to take out all the spark plugs and see where
the pistons are and if there is any damage to the top of them.
thanks

Agreed, chances are slim that the car survied that w/o jumping time. Most
likely a piece of chain guide got loose and wedged itself in b/w the gear
and the cover.

You can start by checking all the rockers to see if they are tight as you
turn the engine over... you'll know pretty quick if you have an issue or
not.

Hi Tad:

Yes you need the cd-rom MB manual for the 126 chassis and you need the
free Super Nervig Index that makes navigating the manual fast and easy.
This group can walk you through any one of the elements you need to fix
and I'd go on to say that when you pull something like the radio it's
the right time to test all of the vacuum elements with that new
MightyVac, check the vacuum switchng valve, replace the fiber node lamp
behind their that lights up many of your switches and more. So, pick a
project and ask away.

I have cut (2) copies of the manual in recent days one for another
mbcoupe type in Easton, MA and well, a spare. If you live in the states
and provide an address there is no telling what might show up in the mail.

BTW: I run an 83 380SEC and I am sitting on a pristine 500 motor for
transplant because I've done all those inspections I laid out in the
earlier post and I am facing a major repair job with cam shafts and
more. In my case the 500 motor was a bargain ($1 plus the cost of Acela
train and lunch) and I drove the 500SEL beast 200+ miles from near
Philly to Boston where it sits awaiting my attention.

Other thoughts...the electric heated washer nozzles may be fouled with
car wax. Just use a fine pin tip to clear each chrome nozzle (2 jets in
each). Clock...if you hear ticking but, it does not keep time, then
it's (2) capacitors from Radio Shack (<$3) to fix. Still need to
investigate why other portions of the cluster are not operational.
There is a kit for repairing the odometer gear yourself if needed.
Pretty sure it's the same company that resells the seat belt arm
presenter gears.

Hi SEC Men,

Holidays are upon us but 2007 is not far behind. What kind of interest level do we have for an East Coast meet, NJ preferred? As many of you know we had a blast here in June 06 and it does take 3-4 months planning to prepare properly, do I hear any noise out there (besides grunting over repairs?)

Best Holiday Cheers,

P
whatever you do .... do NOT attemp to turn engine over at all except
gently by hand
probable senario:
valves bent or broken off.......w/ damage to head and/or piston and/or
cylinder

depending on above... you may get away w only new valves and guides all
the way up to new engine

you have to take it apart and look unless you have a bore scope

if the spark plugs don't "unscrew" then you're probably screwed !

the good news.........
if you do the work yourself..... you'll know a lot about 117 engines
take a lot of pics when dis-assembling

Yeah, I'm not turning the motor over until I pull out all the rockers,
spark plugs take off the oil pan and put in a new tensioner. What I assume
happened was a weak tensioner, records on car state that they used SAE
15w50 oil in it a no-no here in Minnesota when temp is about 15 deg F. So
what i assume happened was they tried starting it tensioner did not get
enough pressure chain was loose took out one of the guide rails and jumped.
What will happen to the car I will fix the motor then supercharge it using
mega squirt fuel EFI management system once I have that car and system
running good i will part that car out and put the engine in my 380. So if
anyone needs parts let me know, the car will be parted with in 6 month if
all goes well.


>From removing the valve covers I have found that everything is intact

except all the guide rails and timing rail is busted. The tensioner has a
piece missing from its pressure cylinder. The only damage I could see on
the head was a tiny piece was broken off where the tensioner goes into the
passenger side head, I think if I find it in my oil pan i can JB weld it or
even having that piece missing I do not think will effect how the car
operates, assuming the valves are not broken. The timing chain has tons of
slack on the tensioner side of the chain. I will start messing with it
during my winter break from school.
thanks
Pavel

Well, I pulled the radio tonight and replaced the fuse in there, and now the
radio/antenna works fine. Radio has a cracked LCD, but it operates. Speakers
don't sound awesome, but they will do, considering how old they are.
I guess I will have to pull the radio out again to work on the vacuum
system, from the sounds of it. But thats a job for a weekend.

Today I took the car to get tagged, and since I didn't have the title
notarized, they wanted $900+ in taxes (6% off retail). I laughed at that and
left, I will have to go back and get the title notarized from the owner. The
car did pass the inspection, so thats good. Do they really think that the
retail value on the car is $15,000?

On replacing the engine with a 500, how will you put it in? Would a shop be
able to install the engine or is that something that only a dealer can/will
do?

When I took the car to get inspected, I noticed the engine still lags when
starting from a stop. Given time, I am hoping that this will clear up.

Thanks, Tad
