Cold weather leak

[markm]

I drove my 56 ht for the first time this year and the cooling systen was 12 quarts low. I have stock rad, because OEM fan ate the piece of shit Desert cooler. Stock V8 position rad keeps it at 160-180 and does not leak in warm weather. Yes, I dont believe in SBCs with 6 cyl pos radiators. Is it possible for a rad to leak slow in cold weather only.

I had a motorhome that had the same problem. Turned out to be a hose clamp that wasn't completely tight. Don

12 qts low?

Thats what I figured a full antifreeze jug and 1/2 another,went for a drive and its fine.

Isn't 12 quarts low just about empty? Where did it go? Wasn't there any evidence of leaking?

A full jug of anti-freeze is only 1 gallon or 4 quarts, so 1 1/2 jugs would be 6 quarts low. Still quite a bit low. do you have a wet carpet, maybe the heater core leaked?

Duh, I must have been using some form of Chicago vote countin math. Still woud like to know where the six quarts went.

Check your dipstick. A gasket leak may have drained it into your oilpan...not a good thing.

No such thing as a "cold weather leak". It's just going to get bigger now.

Could be a cracked block or head too. I would check the oilpan for coolant. I've seen this happen once before....the oil was like a milkshake. If there's no evidence of it leaking out anywhere, it must be in the engine.
