Cold weather
In fairly cold weather.....5 to 20 degree range... This has now happened 3 times and I'm not sure what's going on.The 30 coupe is in an unheated garage and when the outside temperature is in this range, I have antifreeze come out during a period of sitting in the garage for a few days.
This morning, 5 degrees, there was about 4 ozs on the ground at the end of the drip pan. . I started the car up, pulled out of the garage and the radiator was circulating fine. I oringinal thought the hoses were leaking but changed them weeks ago on the second time I saw this. . This morning....a leak ... Any thing I may be overlooking. I have -20 degree anti freeze in the radiator . Tom |

Re: Cold weather
Tom, mine does the same thing. Antifreeze will leak from a fitting where water will not. I am not sure if a hose will contract in the cold like a metal fitting however, no question I experience the same issue.

Re: Cold weather
Tom
in cold weather things contract like hose connections etc. when its warmer or the engine is heated up those connections expand. look closely with a mirror under and around your hoses, and all coolant areas for a trace of where it is coming from. a lot of times it runs down from other areas up higher. it could just be a matter of re snugging the clamps |

Re: Cold weather
At one time I had water come back out of the grease zirk for the water pump. Easy to overlook.

Re: Cold weather
Not only could it be a hose connection, it could well be the drain valve or the coolant pipe itself.

BTW, I understand rubber expands when cold and contract slightly when warm. |

Re: Cold weather
In extremely cold weather -20 or more, the water outlet gasket weeps a little.

Re: Cold weather
Our '29 would weep antifreeze at the hose connections when it would get real cold. Lost about 2 quarts one winter before I noticed it. Car was stored away from home then.
Snugged down the hose clamps and we were set to go. |
