Thanks I'll check it out
Now I am dealing w the euro tailight
got some newer cleaner ;lights
have to use my elec back panels as the us lughts has the sidemarker on different pin than the euro.
\\\

top drivers side top plug has 3 prongs in the car outlet & the euro has only 2 pin plug on top. I'm sure it has to do to how the lights are wired to the control knobs

most lights/prongs are same but sidelights are on 1 & 8 on US also my sidelights wwere modified. they r the very small push in bulb. I wonfer why they changed the side bulbs/
Next modification is on euro sidelights are piggy backed on #6 tail parking as the drivers side has the fog light on pin 8 which is a sidelight on the us version, lucky the rest r the same

anyway
argghhh

Checked the mileage this AM
196969


Took her out today
getting close to the big 197,000



Yeah, curbstoner lied but it is a good car

Took her to Enriques this week
I couldn't stand those slipping belts & thought that the uneven tension on the power sterring pulleys could cause it to wear.
I was not even sure if the belts would tighten on the ole girl.

New belts all nice & tight
a used sachs clutch installed as he said my behr wasn't too good & a new brake booster cable. He checked the brakes & shes good to go.

She likes her sachs clutch
taken her out in the hot summer & she runs 90C & no more belt hiss.

Lastly we almost got rear ended this weekend,
The brake light in the rear window never worked
So I searched for the wire found it wrapped around the attenna
Hooked it up to the brake light in the tail panel & yeah
I got my orange brake light
sae84

I love my Volvo
but gosh I got to give more attentiion to this sweet SEC who has waited so long to get on the road

Long time no see

Update

Spent days trying to charge the battery to no avail.
Would almost not have enuff juice to make the sound when the lock engaged.
Wouldn't get beyond a click with 10 amps on it.

So bought a new mb battery from road assistance.

New rules for 2011 but bad news for Euros
They are not & never were covered for road assistance
Guy said he didn't even get paid 3 years ago when I got another mb battery.

He installed the battery cost $143 this year not bad only $3 more than 3 years ago & it was done. Don;t think he even charged tax.

It did start on his jump so glad it was not the starter & hope I didn't buy a battery for nothing but it had all the signs of battery really low esp the emimic slurr on the lock operation. Now its crisp again.

Took the oppurtunity to remove the rest of the badly disinteegrating hood liner foff...the tech took off some with his back...poor man doesn't get paid & walks away with dust all over him like he came pout of a coal mine...LKOLO

Well its off & someday if I find another set of hands I'll get some adhesive & get the new hood liner in the trunk installed..

Its that really strong 3m spray kind?
1 can or 2? Anyway there is still some glue rersidue on the hood but many places with baremetal for adhesive to stick & anything would be better than the old as it really wasn't doing anything but falling into the engine.

Smog again this year for the SEc & 740 Volvo which is still on the road with lots of new parts as doers the sec that were located this summer from the junkyard...
I
Its been a pretty good year.

...which incidentally I found a vaccum hose on the air cleaner not connected. Gosh 10 years & nobody ever saw it...maybe this year it will pass easier...

Well another year is yet upon us.

3 more miles & I roll over the 197,000 mi mark!


Happy New Year everyone..may our benzes be with us driving us through many day & years of safe journies!!!

This thread is like the energiser bunny...

It keeps on rolling...



Seriously I just started reading from page one again & it's rivoting.
So many things I remember but I gforgot the vanity plate name.

Think it was something like Doc or whatever

Anyway I better make a copy of this as it's turned into a mini series full of memories & lots of rare Euro info!

Thanks to everyone for your invaluable info & incomparable genuine compassion who made this thread possible!

Failed Smog so back to Enrique again.
He said not much he can do
Had O2 sensor changed last smog
He said could be Cat con
$1000 ouch

His advice drive it as it was sitting for a while.
Said Cat Con could regenerate?

Any advise on what to check
hoses charcioal can etc?

To make things worse now the sunroof will open but won't close
Had to manually close it
I think thats a switch?

Been driving it a few days
It really is a sweet car
be nice to keep it on the road

83 500 SEC Euro 198K

i have a 1990 500 sec that recently started to make some noise after getting my leg off the accelerator (when speed get lower by itself without braking)
the car is not a euro car i assume that because i read some posts saying that many features are not available in the euro model but in my car they existe like the adjustable headlights, the bummper, the fire fire extinguisher & many other stuff.....
i aslo read that only the euro 500 sec come with 2.24 differential so i guess because i'm a second owner of the car that it could be replaced & would like to know what's the original one for my car
i should add the car's differential has a place to plug the ASD

it took it to the shop & i was told the differential should be replaced
i took a look at it & i found out that it has this ratio 2.24
i looked for a replacement part but without any luck
i found many others with different ratio like 2.27 2.47 ....
the fact is that i asked the guy in the shop if i could put any one from these other differential on my car, he replied that any change of the original differential could have many results, he said that it might get slower on the start & faster on the high speed or the hills; or the opposite like it could get faster at start & slower on high speed
i'm confused & don't know if that's right
i would like to know what's the difference between these differentials & is there any other differential that i can put
any help would be appreciated
Mark...............................

2 years later & finally got the EGR valve checked & its ok so

Here we go again

2013 Fail Smog on NO again (same in 2009 & new O senser gor No down to pass)


2013 Smog Faili: see pic below




Failed Smog & have had EGR valve checked by MB mechanic & the EGR valve is fine.

History: Failed NO bad in 2009 So changed Oxygen senser & it brought NO way down

Fail Smog: 2009 fail was close




2009 change O senser & it passed & brought NO way down,

2009 Smog pass: below



See above new O sener brought the NO way down 4 years ago.

2011 Smog was very close with NO way up again:

2011 Barely pass smog: Below




So its really pointing to another oxygen senser...????

As well as checking vacumn, dist cap rotor, plugs?
they all are only 2000 miles old.


Cat is also suspect & running it hot has been suggested to burn off residue?
Its a shot.

As far as cat cleaning can I run it in park? Would it hurt the engine to run it for an hour or so?
I'd do it if it could burn off residue in cat. The cat doesn't rattle.
When the cat failed in the
Volvo it would rattle under the car. I guess my driving habits is killing my Volvo too.

Failed dreaded smog w euro

Thanks to Skippy. Tjts1, C Doner, Mava most recently
& all my ole MB Buds who have helped me along this MB journey.

Info on engine


Is that in park or drive? My Idles too low...I can dial it up a bit but is it measured in park? Then it might not be too low

BAR label does say PVC



EGR diagram



A shout at to all.. Hope all your journeys are great ones. Thanks

Its like a freezer.

YEAH!
It's been 2 weeks & its still ice cold.
Enrique said it was empty but was seeming to hold pressure.
I can't believe I waited a few years to spend that $200!
Best $200 I ever spent.

Now as fate would have it I have to get it registered & jump the hurdle of my failing smog!

It certainly sounds like it has Euro parts but they could have been updated. As far as I know the standard US for 1990 was a 560 SEC. You'd have to check if they ever made a 90 500 SEC & for what countries.


I would assume the vin should begin with WDB if they were still using that.
Lower diffs are better in the lower normal speeds. A higher diff could prove harder to run at lower speeds aceleration wise & come into there sweet spot at high speeds. Its not really faster or slower but better performance
at normal sppeds lower is better.If you race 1/4 mile then higher is better
but it will be more clunky at low speeds
& less responsive
Thats my take on it anyway. It would seem best to stay in original diff range as that could affect the way other things perform

I don't know for sure but I would think a 2.24 or 2.27 would be close.

http://www.youtube.com/watch?v=1DRwGkGxq0w

This shows the rpms in gear shifts w fast acceleration. The differential would change these...or so I'd assume

Cool to see the car go into the 120 mph...or is that KPH?

RPM KPH MPH
3000 40 25
3500 50 31
4000 60 37
4500 70 43.5
5500 red 80 50
Shift
3500 90 56
4000 100 62
4500 110 68
5000 120 74.5
5500 red 130 80.7

Gosh seems really fast in KPH but pretty whimpy in MPH

I thought these cars should run 50 to 60 MPH in 2500rpm?

Pics from 2008 for reference.
I'll take new pics & see if we can see anything loose or wrong.
Also I have been asked by others trying to get there lines set up right.

Hope this helps:


Diagram WUR


One way green white valve has white on intake side not listed correctly on diagram


Vacumn Diagram w egr







The patient undergoing surgery back in 2007/2008

IVC & WUR area







Close up










Original electric connection to orig ICV that is not air controlled
I guess I should make sure to tuck this too for visual inspection.



The engine is sort of a mess to put into current smog


Old cap in 2008 not so bad but was replaced with new



Old rotor as found in 08 & was replaced with new





OLD rotor replaced 1800 miles ago & 5 years
Guess 5 years is alot of time to go by.
I chnaged the cap & rotor myself & Enrique was impressed
Cap was not bad but put on a new one anyway...

Guess this is a good place to start. to check current status of rotor since it was pretty burnt.


Will take pics first to get a reference & also to use in case I forget how to put it back together

LOL



On the sad side is running the car just to keep the battery up is probably been taxing the cat as well as the system

Bad me! but I have good reasons
I have a vision problem in one eye its 20 /200 so legally blind.
DMV caught it on a eye test for my lic renewal
so now I have to pass a driving test at DMV to renew my license.

My vision makes it hard for me to change lanes & to span the road.
Thats why I am scared to use the highway as well as its so congested here in so cal that its actually faster to use surface roads.
Add working from home & thats the story.
I have not been on highway in 10 years.

I recently took a driving refresher lesson to help prepare to take the test.
He had me on the highway & I drove it fine for a few exits.
It was scary at first but then I was getting more confident & actually enjoyed it.

I can't imagine how enjoyable it will be to finally get this car on the road.

Took the benz on the DMV test last month & did ok getting on & off freeway but failed for missing a school zone & going 36 which was over 10 miles too fast.
Automatic failure.

So its been a long hard road

The next test date is July 9th. It looks like I may have not have the benz fully registered so can't take DMV driving test with itto take the test with it.
That means taking a Volvo out in mid summer with No AC. Bet the DMV person is really going to love me!

Thanks again everyone for all of your help.

Ha
It was the fan clutch....I was right.
I pulled one 2 years later in 2010 that looked good from a junk yard & had Enrique look at my clutch. He said mine wasn't working & the one I brought was good & he put it in for me!!!

What a great feeling of bonding with my car. My poor baby (now she stays around 90 C)
I also pulled a new brake booster cable & he installed that too.

He installed all new belts for me in 2010 so it was a perfect time to slip that fan clutch in.

I haven't gone a hunting in a few years but it was fun learning to take apart & going thru all the wrecked benzes looking for some jewel parts. One was even a 560 SEC think a 89 90.
I pulled the headlights w help from someone but they are rough & have some broken trim & rubber.

I don't plan on using them so might trade them in the future for something.

It's been a long project but there has been good times!



Too bad I have more hours under the hood than on the road!

Is the euro or Aussy ajustment backwards.

I can swear I have documents that suggest clockwise to lean & anticlock (counter colockwise to increas???
Also wondering about adding tranny fluid to gas for valves???

Any ideas.?

Hope Brissy is well as he really did give me detailed info specific to my euro beast with a airslide valve.

Step 2 More vacumn hose / connection rubber replacement.

View of front driver side.
What is the small cannister on right? I never changed that rubber.




Note loose end of purple hose. No idea where that went...guess lights.







How hard to replace the individual valve manifold rubber sections in each side of intake?
Also

Do these rubber manifold things easily fit into valves? Do you have to remove fuel lines?
If so I'll have to leave this to a mechanic
Mine has # 116 094 02 82




All these things do look old especially the connecting pieces.




there seems to be a section to intake that looks old as well as the plugged valve cover to air cleaner which is a easy replace.

Will have to change this rubber hose too.




Will have to get correct runner stepped connection as old rubber was not replaced as I feared it might be a brittle plastic nipple/
Ill use the hairdryer to remove it but does anyone know if that is a metal or plastic nipple in the intake manifold in 3rd arrow to right?


How do you check vacumn? seems you test the open line & see if its losing? Would I be able to do it with a mitivac.
Saw they are about $30 & might be worth the investment.

Looking foward to a long awaited joy of getting these issues resolved & passing smog.

Guess I'll have to get in touch with our sponsor
