DAMN, I forgot your progeny was of that age!
Goes by fast. Will be 14yo in a couple of weeks, that gives us
a year and change to find/fix car before driving lessons begin.
There is a really nice looking w115 by me. Driver door got smacked
and is now gathering parking tickets. Not mine, but it should really
go to a good home if the owner will part with it.
I have two front W115 doors in storage. U-pull, _with_ mirrors.
Boy says W115 or W123 is all the same to him. We have one each,
so he has samples to examine. Not a choice yet at all, he also
said he might like Swedish. ('Cause it's Swedish, he wouldn't
know one from a rolling dog turd.)
Just trying to get him thinking a bit about the whole process.
Local w123 are either scrap or over priced at the moment. I can keep
an eye for something large enough for a bass, stick, and of
questionable coloration
Sure, that'd be fine. Don't bust your hump over it or anything,
we're far from that point. SWMBA is mighty A about the whole thing.
Feeling left out I guess. Yeah, like she cares about cars...

Re: [MBZ] Overheating 240D revisited
Great criteria! Mine were the same, except I didn't demand manual trans. I want him to be able to drive anything. What he _chooses_ for himself, later, will then be up to him. Early days yet, no guarantee that an MB will be the final choice. But it's nice if it hasn't been eliminated already. A 240D slushbox is NOT on the list. We had one once, I'd consider it dangerously slow. (The difference between it and our 200D manny was unbelievable.) The 300D Chicken Wagon's tranny is bad, probably a B2 issue. A manual conversion would be _excellent_ in all respects, but as I've done this on the 190D it's more work than the plan calls for. He'd lose interest before it was completed.

Re: [MBZ] Overheating 240D more info
Lost coolant may not be obvious just by looking in the radiator if there is an air bubble in the block. I assume this car doesn't have a coolant recovery tank (my 123 didn't). I found it best to test for coolant system leaks using a pressure tester on a cold engine. Wet spots from small leaks tend to dry up before you see them on a hot engine. Also, a static pressure test on a hot engine will give wonky results as temperatures change. But the test for exhaust gas in the cooling system is a great idea and you probably do need to go to a radiator shop (or some place with a sniffer) for that. > -Original Message- > From: dseretakis--- via Mercedes > Sent: Sunday, March 01, 2015 4:45 PM > > It lost some coolant but could be from known area around tstat housing cover. > ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com All posts are the result of individual contributors and as such, those individuals are responsible for the content of the post.

Re: [MBZ] Overheating 240D more info
Were the car mine, I would be very interested in why the system is still pressurized after setting overnight.. Dead cold cooling systems should not have pressure, so , to me, it speaks of combustion air incursion into the cooling system and likely, serious over pressure somehow.. although, the radiator cap should vent anything above the rated pressure... further concern, to me.. Cooling system pressure test would be my next step.. certainly.

Re: [MBZ] Overheating 240D more info
Yes - good question, are you losing coolant? You've got at least one leak you know of, really need to fix that. Pressurized coolant system in the a.m. may or may not be a problem.

Re: [MBZ] Overheating 240D more info
So I've driven the car now for 250 miles with blocked open tstat and no overheating. I'm noticing that the cooling system is pressurized in the mornings. This morning I noticed that the upper and lower radiator hoses were moderately swollen, and there was a puff of air when I removed radiator cap. There was some leakage of coolant from the thermostat housing cover sealed by a rubber o ring which I have not yet replaced. Perhaps coolant leaking because system pressurized?

Re: [MBZ] Overheating 240D more info
Now that you have a forced open thermostat, it's time to do a citric acid flush. You will need a kilogram of food grade citric acid (should be able to find that fairly easily without spending the money for analytical grade). Dissolve in a gallon of water. Empty cooling system, including draining the block through the drain valve or plug. Close drain valve on block and radiator (or put drain plug back in), pour in the gallon of citric acid solution and bring the cooling system up to volume with water. If there is evidence of oil in the cooling system, don't put the citric acid in, put in a half pound or so of dishwasher detergent (without chlorine) or a couple pounds of sodium carbonate -- "washing soda", available at the grocery store. Fill with water. Drive the car with the heater set on full heat. Might need to block part of the radiator in this weather to get it warm, don't overheat it. You want either the detergent or the citric acid to get warm and circulate for a while. Let it cool if it got warm, then drain, flush, fill with water, drive it a while, and then let it cool and drain it. Keep filling and emptying the detergent rinse until it's not slippery feeling, the citric acid mixture until it's not acid (use litmus paper if you can find it, or pH papers from the home-brew store). You don't need the detergent flush if there isn't oil in the overflow tank. Chances are you fill have a ton of crud come out when you drain the block, since I suspect you have a lot of carbonate scale in there that cracked loose from the block when it got hot and dry. And verify that you do not indeed have a "flap"in the hose! It happens with brake lines too. A one-way valve in the wrong direction isn't very helpful.

Even if the thermostat is bad, I would do a pressure flush of the block from the bottom radiator hose up to "blow out anything that might be in the block passages", just to be sure.

When you let off the throttle, the amount of fuel injected goes to almost zero (or exactly zero, depending upon how the injection pump works).

Re: [MBZ] Overheating 240D more info
gassers control combustion by a flapper in the air intake, controlling airflow into the cyl. Diesels run at full air flow all the time, combustion is controlled with fuel. In effect coasting downhill, the fuel is shut off, no heat occurrs and the cylinders are washed with lotsa cool air. nothing to generate heat, cept friction. Still not sure I understand why engine braking especially down hill would lower temps dramatically. Perhaps it causes an air bubble to dislodge? Anyway, I just forced the tstat open with a piece of brass tubing. Let's see what that does. If I get no answers, I will take car to radiator shop. They said they will pressure test cooling system and also look for head leaks. About $100 for that service.

Re: [MBZ] Overheating 240D more info
Still not sure I understand why engine braking especially down hill would lower temps dramatically. Perhaps it causes an air bubble to dislodge? Anyway, I just forced the tstat open with a piece of brass tubing. Let's see what that does. If I get no answers, I will take car to radiator shop. They said they will pressure test cooling system and also look for head leaks. About $100 for that service.

Re: [MBZ] Overheating 240D more info
Yup, it's NOT fixed. I drove the piss out of it today and it was fine. The lower rad hose started warming up indicating coolant circulation. No overheating. Then went to a friend's house and on way back it started again, temp rising, no heat, the usual. It was a 7 mile trip back home that required pulling over four times to let it cool down enough to start driving again. Interestingly, I noticed that heavy engine braking down hill would bring the temps from almost in the red to normal, but once I started accelerating the temp would rise again. Wonder why it did that?

No, not the exact temps, but the patterns - the head is x degrees hotter than the top of the radiator, which is y degrees hotter than the lower rad hose, all relative to the T-stat housing, under these conditions (ambient temp, miles driven at z average speed, etc.).

Around here I'd be shocked if the lower radiator hose was warm at all even driving around in town, it's 17 at the moment, and the coolant will lose all the heat in the radiator long before it goes back into the engine. T-Stat is probably just cracked open, unlike when it's warm out. Idle it for a while protected from the wind and see if the radiator warms up. If not, and the temp climbs, you still have a problem. If it warms up, the thermostat is at least partially opening.

Re: [MBZ] Overheating 240D more info
Run the engine with the radiator cap off, while you watch the coolant through the filler neck. If you see bubbles in the coolant while it is running, you have a cracked head, block cavitation, or leaking head gasket causing combustion air intrusion into coolant system. IF, as engine temp increases, the bubbles increase to the point coolant is surging out of the filler neck.. certainly combustion intrusion, and always overheat will follow if the system is sealed. I suspect the original loss of lower cooling hose clamp was due to over pressure from combustion gas into coolant which simply blew off the hose at the weakest point, which happened to be a weak hose clamp, rather than the radiator hose. Further, I suspect all efforts since have not addressed the original issue, thus cured it.

However, you can only see the outside. It is possible that a crack is between ports inside. the symptoms don't sound like a cracked head though. The best theory that I've heard so far is the floating piece of crap that blocks a passage sometimes, and not others.

Re: [MBZ] Overheating 240D more info
Ah, thanks for the update. So, the next obvious thing should be to pull the head and have it pressured tested, no? The initial cause was a loss of coolant, so checking all those other things doesn't make much sense really. Jaime There are many much less difficult tests that will point towards the problem. 1. As discussed many times, block the thermostat open as recommended by Jim Cathey months ago. In spite of the arguments, 3 bad thermostats in a row is not unheard of. 2. Send an oil sample to Larry to see if coolant shows up. 3. Any good radiator shop can test for exhaust gas in the coolant Numbers 2 an 3 are better than pulling a head for nothing. 4. When it overheats, shoot temps on all areas of the block, head, hoses, thermostat housing, WP, Radiator. That will tell you a lot. None of these tests require a lot of money, but you will get answers. None of these tests have been done. When the head was off did you see any cracks? they are obvious to the naked eye. valve to prechamber, or valve to valve. the limit is 10mm before the head must be replaced. In other words, the head can have 12 cracks up to 9mm and still be ok to put on per the book. If my memory is right, I believe no cracks were found. It is unlikely that a crack large enough to allow exhaust gas into the coolant developed after the head was off, if not cracks were detected at that time. ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com All posts are the result of individual contributors and as such, those individuals are responsible for the content of the post.

Re: [MBZ] Overheating 240D more info
Ah, thanks for the update. So, the next obvious thing should be to pull the head and have it pressured tested, no?

Re: [MBZ] Overheating 240D more info
Question: During the course of all this, has anyone ever physically removed the water pump for visual inspection of the vanes? Years ago.. I had a chevy 283 [may tell you how many years ago it was] that displayed the same symptoms. It turned out to be one of the vanes of the water pump had sheared off and was acting as a flapper valve in the block passages. Sometimes it would be edge wise, and coolant would flow, cooling normal... then it would flip flat across the passage and in minutes, overheat.. It got new radiators, new hoses, thermostats.. the works.. nothing worked... the water pump still pumped water so it looked like there was coolant flow through the radiator... then... the vane would shift [always while driving it, of course] and temp would go to max overheat.. Even when the water pump was finally pulled and the missing vane discovered.. we had a tough time flushing the broken part out of the block... Seems to me, this could be a possible in this case.

Re: [MBZ] Overheating 240D more info
When the car is overheating the heater does nothing. Clear symptom of no coolant circulation. You've missed the years I owned it and drove it and it was fine. It all started a couple years ago with Angie and I headed to Maine, 75mph up I495 and all of a sudden the car smelled hot. Turns out the clamp on the lower radiator hose at the radiator had broken, the hose came off and the coolant all fell out of the engine. I pulled into a handy rest area, zip tied the hose back on got water from a helpful passerby and made it to a roadside rest stop where I got a replacement hose clamp. We made it home and the next day I changed out the water for coolant, changed the oil and kept driving the car for 4 more months. One day on the way to work (during the first warm day of spring) the temp needle started to climb in heavy traffic. When I got to work the coolant was down a quart. I filled it up. On the way home I had to stop on the side of the highway and was down another quart. From that point on I couldn't run the engine more than about 20 minutes or it would start to overheat and spew coolant out the radiator. So we had HeadgasketQ and replaced said head gasket. This seemed to cure the issue for about 40 miles, then it came back. I retorqued the head bolts and the problem was gone for maybe 100 miles. Then nothing I did could get the issue to go away. Somewhere in the troubleshooting phase I replaced the thermostat which changed nothing. I needed a car so I bought the Jetta and the 240D sat unloved for a year until I hauled it to Dimitri. There have been 3 thermostats in the car from 3 different sources since the issue started. I find it far fetched that all three (2 of which test good in a pan of water) would fail in exactly the same way but only sometimes.

Re: [MBZ] Overheating 240D more info
If the flap on the bottom of the thermostat isn't correct, it won't work properly and will cause overheating if it doesn't close off the short circuit around the block it is supposed to seal off. This is designed to heat the engine up more quickly, and in spite of the very simple design, I'm always amazed at how many variations there are from the factory spec. After all, to make one you would only need measure a factory thermostat and make sure the diameter of the flap is the same and the locations hot and cold match. I've had this issue many times (radiator caps are also a problem, many don't seal well and often are rated for 14 psi rather than 20) My parts supplier only uses Behr or Whaler thermostats if he cannot get genuine Mercedes, and even then occasionally you get a bad one. Behr and Whaler are OEM suppliers, so they always fit, have the correct bleed valves in the proper places, etc. Other sources are usually correct only in the diameter of the main housing, quite often that is the only thing identical. Peter Good write up Peter. The thermostat is designed to circulate through the block and until the coolant gets warm enough to generate some heat from the heater. Once the coolant gets above operating temp, the main thermostat opens up and allows the coolant to go into the radiator for cooling. IF nobody has checked the radiator with an IR Thermometer when it is overheating, then we really don't know for sure the radiator is good unless a radiator shop did a flow test. Suspects: thermostat air in coolant something blocking flow in the block Something blocking flow in the radiator, hoses, etc. Simplest tests: Blocked open thermostat IR thermometer: measure temps of entire system when overheating. Has anyone tried turning the heater and fan on full blast when it is overheating? that is an old time trick for desert and high altitude driving. The heater pulls heat out of the coolant too. Often it makes the difference between go/no go on deetriot iron of the 60s/70s. Fortunately, the MB cooling system is pretty robust.

At the risk of being redumdant ... The thermostat needs to be installed in a particular orientation (arrow up). There is an air vent passage in the thermostat casting to vent trapped air the thermostat; if plugged this would prevent proper bleeding of air when re-filling the system. ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com All posts are the result of individual contributors and as such, those individuals are responsible for the content of the post.
