I've been a mechanic most of my life and never smelled a dog who smelled like coolant; Bad yes, but not like coolant.

Squeeze the juice out of your dog's anal glands and get back to me.

OK, sounds like the 205F is sort of normal for modern cars. I think I understand. So, the key is pressure. I have a guy who services all our cars and I will have him do regular pressure checks. He'll put that in his computer and they'll do it whenever I am there for oil, or other service.

You guys really know yer stuff. I appreciate the concern and comments and help. I just had to run some errands in the car and WOW I sure like it. So, I am hoping the worst is past!

OK, this has some interesting sidelines, here Fido here boy!

This is the one I've used for oil analysis:
Fleetguard Oil Sampling Kit-Geno's Garage

$19.95 at Geno's. PDF Report comes back in about a week or so. The thing I like about this system is as you retest they stack your new results on your old results, see trends easily.

Hi, I have tried to do this un-successfully several times. [on different dogs] The Poodle Parlor and the Vet have done it for me. So the bad smell is only hear-say because I have only heard/read about it.

A cracked coolant recovery tank is more than likely a factory defect, not something that you did. Also your recovery tank should already have cold and hot level marks on it. [mine does]

Chrysler does not shut down an engine at overheat.That would be a safety issue-stuck in a traffic lane-not good.You would get notified of the overtemp by any number of ways depending on year and model.

What year and engine does the 300 have?

It is a 2012 and has the 3.7L V6 and 8 spd.

Our dog leaks this fluid from time to time unexpectedly. It smells like coolant landing on a hot exhaust pipe.

Ok,ok, I promise, that's my last mention of it!

Glad that the bad experience was without injury or damage. No offense, but the lesson here is to pay attention to your nose rather than waiting for the computer to tell you that coolant is leaking and steaming. Your 300, like my new Grand Cherokee and most new vehicles, is heavily sensored and processor controlled, but our eyes, ears and nose have an intuitive advantage in sensing impending problems. If it doesn't smell right, it probably isn't right. I'll christen my new GC Diesel with 2000 mile tow next week, (2200 mi of winter mountain driving thus far) and will be reminded by your experience to look, sniff and listen carefully.

Safe Travels,

Most, if not all, of the GM products will go into a protection mode at extreme overheat temps, as a final failsafe, in order to protect the engine. I'd be surprised if Chrysler didn't do the same. But I've been surprised before.

This from 2013 Silverado owner manual.

Overheated Engine Protection Operating Mode
If an overheated engine condition exists and the ENGINE POWER IS REDUCED message displays, an overheat protection mode which alternates firing groups of cylinders helps to prevent engine damage. In this mode, a loss in power and engine performance will be noticed. This operating mode allows the vehicle to be driven to a safe place in an emergency. Driving extended km (mi) and/or towing a trailer in the overheat protection mode should be avoided.
Notice: After driving in the overheated engine protection operating mode, to avoid engine damage, allow the engine to cool before attempting any repair. The engine oil will be severely degraded. Repair the cause of coolant loss, change the oil and reset the oil life system. See Engine Oil.

Bob4x4 · 02-20-2014, 06:39 AM

Power de-rate is common industry wide.that does not shut down.I see melted engines still since some will drive till it stops not heeding any warnings.
The 3.6 (3.7 is no longer built) has had many head issues in it's early release date version.They have improved but still seeing too many.Issue usually starts by tripping intermittant miss fire dtc's.The 8spd trans is awesome.

dznf0g · 02-20-2014, 06:47 AM

Power reduced mode is a little different than overheat protection. Reduced power just limits throttle response and road speed. (fly by wire models) Overheat protection takes it a step further by alternating cylinder firing to try and reduce jacket and head temps.

Looking forward to your next run Mark , I'm staying at SAMs family spa let me know if I can help

mstephens · 02-20-2014, 07:02 PM

Of course the exact moment was filled with terror and so I could be wrong here, but I think as I pulled over and just as I got the arse end of the TT off the slow lane and onto the shoulder, the engine shut off. I pressed the start button and ...nothing. I waited a long time before trying it again.

There were at least two alarms going off and two symbols lit on the dash. Now I know someone is thinking, "Jeez, wasn't he paying attention to things?" I WAS! I was glued to the trans temp. Who knew I shoulda been watching the coolant. It went sour so fast it was unbelievable. Kinda like a traffic light...green...yellow...red!

PS. No one commented about the two Airstreamers that went flying by. I guess I can't blame them, but I felt a bit let down.

Cool! Thank you very much. Should be in a day or so.

From what you said, it wasn't a very safe place to stop - you said that you were afraid to open your door for the cars whizzing by at 65 mph and the trailer was barely off the road.

It's tough. I'd certainly want to stop and help if I saw an Airstream broken down along the road (and in fact I did offer help to one that was obviously in distress in a parking lot once), but at the same time it's just not always going to be possible.

Under heavy load, the overheating following loss of sufficient coolant is extremely rapid, less than one minute advance warning from the gauges.

In the early days of automotive travel, there was a strong tradition of mutual aid. I've commented elsewhere on its sad decline, born of the presumption of 1) universal availability of cell phones, 2) widespread availability of free roadside assistance, and 3) the reliability of present-day cars being so much higher aside from cases of total neglect.

I still stop to help although on the whole I typically make the acquaintance of people with neither means nor decision-making ability when I do.

mstephens · 02-21-2014, 08:21 AM

I think it probably is the cell phone that has changed the idea of stopping to help others. It's pretty fair to assume people can get help on their own. It's kind of an old fashioned thing to stop and offer assistance. Oddly, there was no cell service on that hill.

I don't want to say I was bitter or anything dramatic like that. We are adults and can take care of ourselves. It's was just a funny feeling to see not one but two 'streamers whiz by in the course of 15 minutes when normally we wouldn't see on on a whole trip. I am going to make a point myself to think more about stopping if I see others stuck. I have never come upon a 'streamer in trouble, but I think I will make a point of stopping if I do.
