Re: [MBZ] 190D continuing saga

[Dieselhead]

Go to buyMBparts.biz  and there are instructions for other brands.



Hi Rusty,
Perhaps I missed an announcement -  is Buyeuroparts still 
operational?  When I try to go there for Porsche parts I get 
re-routed to the MB site- does than mean you no longer sell parts 
for non-MBs?   If so can you tell me who has your Porsche inventory?


Thx
Larry

Other than the fuel gauge bounces a bit once in awhile I see no signs of any 
gauge particularities, everything works fine and theres no abnormal activity 
when the blinker is on or anything like that.

Have you checked ground connections?  It should effect a lot
more than the temp gauge, but maybe that's the only one that's
catching your attention.

If it were my car, I would want to be confident of that
connection anyway.

Re: [MBZ] 190D continuing saga

[OK Don]

There's also the possibility that the thermostat housing is corroded to the
point that the thermostat doesn't close the top port when it's fully open,
preventing full circulation of the coolant. I've never seen/experienced
this myself, but have read about it - here - though several years ago.

Re: [MBZ] 190D continuing saga

[Dieselhead]

This sounds exactly like a bad temp sensor or bad relay (most likely 
the "sensor" which is only a switch in this case).


It's possible it has an air pocket, but that's easy to fix -- 
squeeze the upper radiator hose flat (engine cold, of course) and 
crimp the small top line from the radiator to the coolant tank shut, 
then release the upper hose and let it expand back to normal.  This 
pulls coolant off the bottom of the rad into the block.  Repeat 
until it stops sucking coolant out of the tank when you let go.


Those electro-magnetic clutches can be a pain.

Peter


It seems to me, that after the results of cleaning the temp sender 
and terminal, combined with the results of the IR thermometer, that 
you have symptoms of only faulty readouts.


I'd say you can live with it, or try a new/different sender. (maybe 
replace the connector too)


It also seems you have a problem with the electric fan switching, If 
I read that post correctly.

Re: [MBZ] 190D continuing saga

[Max Dillon]

If you've driven up a hill or two, I doubt there is any air pocket.

After testing the thermostat, I'd try a citric acid flush before replacing the 
water pump. Fan is really only needed at low speed if the rest of the system is 
healthy.

Sorry Curt - coming into this late so I don't mean to be redundent. From
the sound of the description below - you have already done some work. My
first stop is always at the work I have done, making sure you have a fully
bled system with no air pockets. You already have the IR thermometer, so
the next think I would do would be to check the temp across the radiator,
looking for a cool spot. While unlikely, you could hae a colapsing
radiator hose restricting flow.

Gould luck, I hate these gremlins. I currently have a randomly overheating
limo where the cooling fan doesn't turn on and it over heats - but by the
time you look at it the fan has come on and won't go off and works
perfectly. Definitly annoying.

Thermostat for all 601 and non-turbo 602 should begin opening at 85 +/- 2, 
fully open at 94 degrees centigrade (that's what they use in Germany, Rich and

degrees really quickly.

I didn't pull over and check the temp with my IR thermometer which I should 
have (looking weird on the side of the road be dammed) but my experience thus 
far shows that the relative position of the temp gauge is right, meaning as it 
rises the temp is really rising, although the gauge itself is usually off about 
10C. So the car probably wasn't really overheating like I was afraid of but in 
the moment you get nervous...

Anyway the revving thing makes me wonder if I haven't got a defective water 
pump. I can't see where its leaking and the coolant doesn't go down a 
noticeable amount.

I suppose what I really need to do is replace the temp sensor but even a sensor 
not giving me the right temp is still giving me information that says the temp 
of the engine varies rather a lot (confirmed with the IR thermometer).

Ideas?

It's not the radiator's fault if it's crudded up...

The radiator is only 9 months old. I hope it isn't that.

I would definitely focus on the radiator. If you have some blocked or
clogged tubes it can manifest itself as you describe.

Your IR thermometer will tell you right away if you catch it while it is
close to overheating.

Look especially close at the center of the radiator.

I would definitely focus on the radiator. If you have some blocked or clogged 
tubes it can manifest itself as you describe.

Your IR thermometer will tell you right away if you catch it while it is close 
to overheating.

Look especially close at the center of the radiator.

Re: [MBZ] 190D continuing saga

[Peter Hertzing]

Sorry Curt - coming into this late so I don't mean to be redundent.  From
the sound of the description below - you have already done some work.  My
first stop is always at the work I have done, making sure you have a fully
bled system with no air pockets.  You already have the IR thermometer, so
the next think I would do would be to check the temp across the radiator,
looking for a cool spot.  While unlikely, you could hae a colapsing
radiator hose restricting flow.

Gould luck, I hate these gremlins.  I currently have a randomly overheating
limo where the cooling fan doesn't turn on and it over heats - but by the
time you look at it the fan has come on and won't go off and works
perfectly.  Definitly annoying.

Peter

[MBZ] 190D continuing saga

[Curt Raymond]

So yesterday morning things seemed good, temp stayed below 100C.
Last night on the way home I got stuck in heavy traffic and the temp hung 
around 110C with trips up to the white line just before the red line.

It was cool out, maybe 65F so outside temp is not much of a factor.

One time it was getting high, I was running the cabin heat which was blowing 
hot air really well but making no difference and in desperation I slipped the 
trans into neutral and revved the engine which brought the temp down about 10C 
degrees really quickly.

I didn't pull over and check the temp with my IR thermometer which I should 
have (looking weird on the side of the road be dammed) but my experience thus 
far shows that the relative position of the temp gauge is right, meaning as it 
rises the temp is really rising, although the gauge itself is usually off about 
10C. So the car probably wasn't really overheating like I was afraid of but in 
the moment you get nervous...

Anyway the revving thing makes me wonder if I haven't got a defective water 
pump. I can't see where its leaking and the coolant doesn't go down a 
noticeable amount.

I suppose what I really need to do is replace the temp sensor but even a sensor 
not giving me the right temp is still giving me information that says the temp 
of the engine varies rather a lot (confirmed with the IR thermometer).

Ideas?
