Re: [MBZ] W123 1985 300TD ACC (heating system) 101
Have you checked for loose belts or related hot bearing? If you have a hand held pyrometer, you could stop and check to see if any of these items are running hot. I had a similar problem on a 240D with a bad idler pulley bearing. Couldn't figure it out until the bearing froze and smoke started coming up from around the hood. Gerry From: "andrew strasfogel" Then last night took a long RT to Columbia, MD (25 miles each way). On the way out, at milepost 10 I got hit with a rich smell of burnt engine air. This lasted 5 minutes before going away! On the way back, at 9 PM, I drove in both highway and stop and go traffic using the same ACC settings as the earlier trip. The smell never came even once! I am beginning to think I am more in need of a compression test on the exhaust system, as this is a DRY smell that IMO is not sweet enough to be coolant. I do not have any coolant leaks under the hood, and my thinking is that if the heater core were leaking the smell would be more or less continuous. Therefore, the episodes of smelly air are caused by the fumes entering through the outside air intake (the two grilles beneath the front w/s) that are controlled by something episodic...

Re: [MBZ] W123 1985 300TD ACC (heating system) 101
In my experience, once the heater core is contaminated externally, you will never get rid of the smell unless you remove it and wash it. At that point you can pressure test it directly. I had a smelly heater core in a VW, I removed the core and pressure tested it and it didn't leak. What I suspect is that a PO put stop-leak in the system after the leak started, sealing it. But the smell remained until I cleaned the core. Actually I just replaced it because I didn't want to deal with any later problems.

Re: [MBZ] W123 1985 300TD ACC (heating system) 101
Yes, the ACC does switch between "more" and "less" outside air but it's always drawing _some_ outside air. In max AC mode it would be mostly recirculating. I don't agree that a pressure test would identify a leaking core. The leak may be very small, but enough to produce a detectable smell. Also if the heater valve is not open when the pressure test is done, the core is isolated from the rest of the system.

Well, obviously, there are no guarantees, but, if it won't hold pressure, then it is leaking somewhere. If you cannot see evidence of leakage under the hood, then it may be sufficient evidence to cause you to look further into it. One other alternate idea might be to disconnect the heater core and flush it out with water to rid it of the anti-freeze and then run for a bit with the heater core out of the system and see if the smell disappears.

One other hint: The smell is intermittent and seems to get activated
when the ACC "clicks" to another mode or function. Does the ACC
switch between outside and recirculating air and if so, when?
And does everyone agree that a pressure test of the cooling system
would definitively either rule out or implicate a leak in the heater
core?

On a W123, it in necessary to remove the center console, the

not required, but I found it helpful.

I'm pretty sure I didn't remove the steering wheel. I don't recall having to open Freon lines, but that car did not have a functioning air conditioner so I may have just forgotten. -- Philip ___ http://www.okiebenz.com For new and used parts go to 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

Someone set me straight on this please, isn't the cabin air taken from the air box that resides behind the battery tray? Feed of fresh air comes from the grill just below the wipers? There is an access hole from that air box that drains into the engine compartment but it's only about 1.25 inch hole.. just the right size for a mouse to find shelter and build a nasty smelly nest. Could your problem be from this airbox being comtaminated with critter "stuff"??? Just a thought, might be worth pulling the cover/screen/grill off and having a look? HTH, Grant...

The only good thing I can say about replacing the 123 heater core is it's slightly less hard than a 126. Philip: Correct me if I'm wrong; to replace a 123 heater core don't you need to remove the dash, console, all ductwork, steering wheel, and then remove the entire HVAC box/assembly, which requires draining coolant and removing Freon? -Original Message- From: mercedes-boun...@okiebenz.com [mailto:mercedes-boun...@okiebenz.com] On Behalf Of Fmiser Sent: Tuesday, April 24, 2012 3:01 PM To: Mercedes Discussion List Subject: Re: [MBZ] W123 1985 300TD ACC (heating system) 101 > Rich Thomas wrote: > It is probably leaking out the heat exchanger up in the duct > work, some pinhole leak or something.

It is probably leaking out the heat exchanger up in the duct work, some pinhole leak or something. The only way to deal with that is to replace the heat exchanger. Have fun. I was driving one day in the fam's 67 Buick Skylark and sitting at a light it started belching coolant down in the passenger footwell. ruhroh. I pulled over somewhere, found a payphone and called my dad to tell him and ask what was going on. He says the heater core is leaking, needs to be replaced. Luckily I was just down the street from a pretty good gas station/repair shop (we had no cell phones back then but actually had gas station repair shops, imagine that!) so I drove it in, my dad came to get me, they replaced the heater core for not much money. It was actually pretty easy to get at them up under the glove box, if you were something of a contortionist. I ended up changing one in some other car I had, not a lot of fun but doable. --R On 4/24/12 1:23 PM, Andrew Strasfogel wrote: If so, why can't I smell anything under the hood yet it stinks up the vent air? ___ http://www.okiebenz.com For new and used parts go to 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

The mono-valve controls the flow of hot coolant to the heat exchanger. The fan blows outside air across the heat exchanger and into the cabin. Testing the heat exchanger is same as testing the radiator: pressurize the entire system, and if the pressure drops, you have a leak. Test YOUR theory by taking a sample of all the fluids from your car and heating them up on your stove. If any of them are responsible for your smell, then you'll know which system is leaking.

Well, they're not leaking. I stil think this smell is generated from a liiquid burning on a hot surface. Logically, it's either 1) an oil, PS or SLS fluid, or antifreeze leak under the hood that emits a noxious smell when the engine warms up. The odor is somehow drawn into the air intake. This seems unlikely because the rubber gasket (seal) running across the top of the firewall is intact. 2) the air picks up the odor after encountering the WARM heat exchanger.

The smell of antifreeze is quite distinctive, sweet, not "burnt" to my mind but perhaps you might think so. Remove the coolant tank cap (with a COLD engine) and take a whiff. Is that the smell?

Re: [MBZ] W123 1985 300TD ACC (heating system) 101
Makes perfect sense to me: pressure test it. If you don't have one, you should be able to borrow a cooling system pressure tester from AutoZone, etc. Typically, they charge you for the tool and then refund your money when you return it. I found this particular tool so useful I kept it, but then I had three 20+ year old cars at the time.

Stick some pine tree mirror decorations down in the vents, or you can go the full ME cabbie route and get the gold crown with various scents to set in the middle of the dash. There are also some little cans they sell at El Mercado de Wal that have a gel sort of scent in them, and they last for a coupla months. --R On 4/23/12 4:06 PM, andrew strasfogel wrote: No, it's not a normal smell when SWMBO (who has a very refined palate and sense of smell) notices it and remarks about it in an uncomplimentary way...

Pressure test the system. Find out if it holds pressure. If not, then it is leaking somewhere. Randy On 23/04/2012 1:57 PM, Kaleb C. Striplin wrote: Are we sure this smell is not normal?

Re: [MBZ] W123 1985 300TD ACC (heating system) 101
Well, the smell came back on a trip this afternoon when I stopped at a light. I popped the hood and there was nothing going on - no leaks, burning smell, or any indication of trouble. So it appears that the smell is being generated inside the system once fresh air has entered the car through the intake.

up to normal operating temperature but only after the heat engages Guck on heater core cooking off? You're definitely sure it does not smell like hot antifreeze? 1) Where is the intake for the outside air? Grille under the wipers. Is your hood lid seal intact? 3) Could oil somehow have been interspered inside the vent system, which might cause a burning smell to emanate when warm air passes through the interior duct work? If so, how could that be addressed? Disassembly and cleaning? Would be nasty. 4) Could there be a crack in the firewall that allows engine smells to pass inside the car (doubtful) Hole can rust behind battery. -- Jim ___ http://www.okiebenz.com For new and used parts go to 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

Re: [MBZ] W123 1985 300TD ACC (heating system) 101
1. If memory serves, the intake is the grillwork between the back of the hood and the windscreen. 2. The blower uses a fair amount of power and could have hot spots, such bearings. 4. Holes in the firewall under the battery shelf are common. I believe this ACC system has a temp switch on the engine that inhibits all heat functions (except defrost) until the coolant reaches about 100 degrees F, as I recall. I'm not sure what s sooty smell is. -Original Message- From: mercedes-boun...@okiebenz.com [mailto:mercedes-boun...@okiebenz.com] On Behalf Of andrew strasfogel Sent: Friday, April 20, 2012 4:44 PM To: Mercedes Discussion List Subject: [MBZ] W123 1985 300TD ACC (heating system) 101 So I am still stymied at the episodes of a sooty smell emanating from the air vents in my 1985 CA version 300TD wagon.
