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
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

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.

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). With no fuel input, there will be no heat, as previously mentioned. No fuel --- No heat --- The cooling capacity is excess of what is needed --- Engine cools down.

Re: [MBZ] Overheating 240D more info
I just remembered a similar problem a friend had that no mechanic in the small town where we lived could explain. It turned out that a piece of the rubber that lined one of the radiator hoses was periodically blocking the water flow. Since there were bends in the radiator hose, no one could check the hose visually. They put two of the new universal hoses that could be bent to fit on the car and that solved the intermittent overheating problem. After that they cut open the old hoses and verified the cause of the overheating. I wonder how old the hoses are on this car?

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 flapin the hose! It happens with brake lines too. A one-way valve in the wrong direction isn't very helpful.

It was no more than 15 degrees out when I was driving so maybe you are right that coolant is losing heat in radiator prior to returning to engine. Interesting hypothesis!

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.

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
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.

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. The only time I had to turn on the heater was mountian climbing at high altitude. At about 12k feet my 200D (now 2.4) ran out of cooling capacity, and we had to turn around. The escort Diesel tended to overheat at about 4-6k feet. If I understand this correctly, Dwight ran the car for miles and years without problem, then the over heating started. If this is correct, what changed while the car was in Dwights ownership? There appears to be a change between no problem/problem.

The best theory that I've heard so far is the floating piece of crap that blocks a passage sometimes, and not others.

If so, and aggressive, extensive citric acid cleansing might dissolve it.

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.

While it might not have clearly defined the issue, it certainly would narrow it down and point in the direction of the problem. You guys have been spinning your wheels on this for far, far too long. That being said, thermostat reliability between all of the suppliers has been touch and go for years. I recall this being an issue as far back as the late 1980s when I had my first MB - a 1980 300TD. I remember going through several new thermostats from different vendors before I got one that worked reliably. Randy Steele, my parts supplier at the time and a former dealer parts guy, expressed his frustration with the lack of reliability of thermostats. I don't recall which vendor was the worst offender, but he made it clear they all had issues.

Re: [MBZ] Overheating 240D more info
I think the key point is that the coolant doesn't seem to be circulating. If you don't have hot water in the top of the radiator when the engine is hot, you don't have circulation. Without circulation, you will overheat. So either (1) there is an obstruction, (2) the water pump isn't working, (3) the thermostat isn't working, or (4) there is enough air in the system (doesn't take much) that the water pump can't overcome the head pressure. In terms of simple, I'd start with a thermostat that's jammed in the full open position to rule out that possibility. ___ 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
I really think that would be the next troubleshooting step. Jam the t-stat full open to force full flow to radiator, if it still over heats, either obstruction or water pump (or cracked head, leaking head gasket, bottomed out head bolts, but there are other tests for those). -- Max Dillon Charleston SC '87 300TD '95 E300 On February 20, 2015 6:25:44 PM EST, Scott Ritchey via Mercedes mercedes@okiebenz.com wrote: I think the key point is that the coolant doesn't seem to be circulating.

RB ___ When my '83 240Ds electric A/C auxiliary fan went bad, the temperature would go up sitting at a stoplight. While I had the electric fan off putting in new bearings, I found that the A/C condenser had a lot of bugs and debris blocking airflow. There was also a lot of debris between the condenser and the radiator. I cleaned them both with strong detergent and a water hose. Since then the indicated water temp runs lower and there is little increase while idling at stoplights. Even though that happened during the hot Florida summer, I'm not sure the outside temp has a lot to do with the water temp since it is controlled thermostatically summer and winter, and the water flow through the radiator is minimal at low RPM. Like Jaime, I hate these kinds of problems so I do a lot of testing and information gathering before anything else. In this case I would buy or borrow a very accurate IR tester and measure post-driving temps in both my car and an identical car for comparison.

Re: [MBZ] Overheating 240D more info
How about installing a water pressure gauge? I believe you can get such a thing for outboard motors. It could be tapped into the temperature sensor hole if nothing else. Or maybe some form of flow meter? Something that would indicate if pressure changed or flow was different when the temperature gauge rises? Some little water wheel that would turn when the coolant is flowing and stop or slow down if the flow lessens. Does such a thing exist or who do we know that could make such a thing? Could hook it into the heater hose fairly readily?

The thermostat has been replaced at least twice, Dimitri and I both did it and I find the idea that we had 3 bad thermostats unlikely not the least of which because I tested two of them. I don't think it could be the wrong water pump, remember its had this pump for years. I drove it something like 25,000 miles on that pump. It could be a bad pump but Dimitri has been in there and checked it out and passed it.

If the thermostat works (and I believe it has been changed at least once) and the water pump is intact and working, then why would there be no flow? It has been suggested that the block passages are blocked. Is there only one sort of passage that could be blocked and stop the flow? If there is something loose inside that can move around, it might explain why it runs fine for a while and then just randomly overheats. The chunk might be such that it lays in the passage until something causes it to shift to an upright position for a while. I also wonder if there is any chance that the impeller on the pump is loose enough that it sometimes does not spin with the shaft and move fluid? Or, is there more than one sort of pump for these things and does it have the correct pump? One would think that would result in overheating most of the time, but maybe weather conditions make a difference? Things like this are interesting but not for the poor soul who owns the vehicle.
