    Our 2003 Peterbilt has an anti freeze leak in 20 below weather. Our mechanic said it is called a cold leak. Is this true? We put up to 1 gallon a day in the engine. When it is that cold or colder.

    Where is it leaking to?


    If its leaking internally then you've got a problem. External leaks you should be able to tighten up the hose clamps etc.

    The leak is external, you can see it running from under the truck. You don't notice it as much when in warmer weather. We will have to check the clamps, why the mechanics didn't do that, I'll never know. Thank you Brickman

    Forget the truck make, but what's the motor?

    I'll guess Cat, and I'll guess the leak is right motor side, external, and not a hose clamp.

    Its got to be fixable. Could be a gasket on any one of the water accessories on the right side.

    What am I missing here? Okay, -20 and the motor leaks coolant. That tells me it's happening only when the engine is off in these temps? Yeah? Otherwise the engine would be running and have some temperature showing on the temp gauge at idle, thus making the fridgid outside tepms moot. No?.. Color me curious, and do tell.

    Details girl...

    Cold leaks and hot leaks are just a way of troubleshooting a leak. Point is, it's not supposed to leak. Bad clamp, bad hose, bad gasket: fix it!
