adallak Posted January 21, 2011 Report Share Posted January 21, 2011 It is quite cold in the northern part of the country and Canada.Check out your antifreeze concentration. Mine is close to 40/60 (have not done it intentionally and fixing it up in LT1 engine is such a pain). That makes me nervous. It is going to be -12°F here in Massachusetts in a couple of days. I will probably run the engine in the middle of night to be safe. For 15 lb radiator cap: 60/40 -62°F (-52.2°C) +270°F (132.2°C) 50/50 -34°F (-36.7°C) +265°F (129.4°C) 40/60 -12°F (-24°C) +224°F (107°C) I recommend this tester. It is very accurate and you can calibrate it (or check out) with a cup of coolant with known concentration.

Cadillac Jim Posted January 21, 2011 Report Share Posted January 21, 2011 From the Dextron bottle: I don't have a curve of boiling point versus antifreeze percentage. Where did you get your figures? If I have a full set, I can add that curve. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

JimD Posted January 21, 2011 Report Share Posted January 21, 2011 http://en.wikipedia.org/wiki/Ethylene_glycol The actual boiling points are much higher in a pressurized system (15-16 psi). Of course. But your first post in this thread addressed freezing temperatures of various ethylene/water mixtures. What you also have to consider is the time involved. Degree hours (or degree days) are a factor. Water (for example) does not instantaneously freeze when the water temperature reaches 32 degrees F. Depending on the volume of the water, there is a time factor involved with removing the (heat energy) calories from the water. As if the time factor is not enough of a complicating factor, consider that the volume of the water (for example) is reduced as the temperature is reduced (the density of the water is increased). Up to a point after which the volume increases. And that volume increase is the physics that can and will do major damage to metal parts. Think in terms of degree/hours instead of instantenous temperature. Jim Drive your car. Use your cell phone. CHOOSE ONE ! Link to comment Share on other sites More sharing options...

Hopefully, the inertia will keep the temperature of the coolant high enough until the air gets warmer in the morning. There should be also density fluctuations or crystallization centers (say impurities or air bubbles) to start the freezing (crystallization) process. The process itself can last fractions of a second. I was told buy a guy who would not exaggerate that he had made a small pond to freeze by shooting a gun in the air. Besides, ethylene glycol mix with water has different thermodynamic characteristics compared to pure water.

adallak Posted January 24, 2011 Author Report Share Posted January 24, 2011 UPDATE. The temperature went down to -22C (-8F) last night. At 1.00 am I fired up the engine and let it idle until the thermostat opened. It took about 25 minutes... In the morning I saw mix of ice and liquid in the coolant reservoir. The radiator hoses were soft, so, hopefully, there was the same mix inside the radiator and less likely in the engine block. Cannot wait to fix the coolant mix up weather permitted!

The coolant reservoir I bought from gmotors.com came with defects, which make any coolant refill /drain very time consuming. Will fix as soon as I can. It makes sense to open the reservoir and check the condition of coolant when it is so cold outside. I am sure some of us can be unpleasantly surprised to see ice mixed with coolant.

BodybyFisher Posted January 24, 2011 Report Share Posted January 24, 2011 Well if you let your car sit without driving it, its at risk if you saw ice Does the tank on your car hold pressure?

It is kind of hard to explain, but it took a while to realize the reservoir was defective. You have to play for an hour or so to have the work done. Hopefully it will be much warmer when I am back and I will be able to fix it. The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...
Cadillac Jim Posted January 24, 2011 Report Share Posted January 24, 2011 If you see ice crystals, you risk the radiator and/or heater core and/or bypass clogging with ice crystals and the car overheating. I would start it for a few seconds, then let it sit, start it for a minute or two, then kill it and check the coolant tank for ice crystals. When the coolant is free of ice crystals, then start the car and go, but watch the temperature gauge for anything tricky. If it starts a march up from Cold that looks a little too determined, pull over and shut off the engine for a few seconds. The idea of siphoning out some of that water and putting some antifreeze in there also strikes me as a very good idea. I wouldn't driver cross-country with the mix that far from 50/50 because of the lower boiling point. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

BodybyFisher Posted January 24, 2011 Report Share Posted January 24, 2011 Jim, the impression I got was that Adallak was flying to SF, and letting his car sit till he got back, that concerns me a lot... I would like to see him dump a gallon or so and put straight coolant in, but if he is not feeling good and leaving he will have to take a chance Adallak, check weather.com to see how the temps are going to be Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...

No, it will stay for three nights in the parking lot of Logan. It is much warmer up there! lol Gentlemen, thank you for all the advice. Believe me, I know what is going on and monitor it closely. Actually I was doing it all last night! As some of you may remember I got in ER twice on the same day because overworking some abdominal muscles. This car is so heavy, the tires , everything! It virtually disabled me for two months. feeling a bit better now, but the pile of medical and EMS bills do not make me fell better. Insurance is not going to cover some of the bills. I did not realize a five minute drive to hospital an EKG and an injection (salty water I guess which bruised my arm for two weeks and probably clogged some arteries...oh well) alone cost around $400. The total EMS bill is about $1,200. Those folks are amazing. In ten years I paid several tens of thousand dollars as self-employment tax (15.3%) which is Medicare and Social Security. NEVER ever got any cent from government or whoever, and when I needed just a little help I have to suck up all the made up costs of unnecessary "service". At the same time every drug addict in the town gets free ride to hospital when they overdose. I guess, that's where all my money goes. That's the reason I do not want to do any work on the car right now. May cost me several Fleetwoods easily!

What did you do to your ABs to cause such a medical emergency?, I never heard about this Enjoy your trip! Mike, that day I worked on my brakes, took off and put in all four tires probably twenty-thirty times, later tried to loosen up a stuck lug nut, etc. Nothing special. My ABS are pretty good, but some muscles right under the lower ribs got probably overstreched. Later had what appeared to be an uncotrolled severe muscle spasms. Very painful. Something just pops out and you cannot put it back. Spent some 40 minutes laying on the floor and could not even move. Finally gave up and called 911... Now I realize that age is not just a number! LOL Well, just noticed coolant is dripping from the connection of the oil cooler line to the radiator side tank. Something did go wrong! Okay, will take a shuttle to Logan.
