Heater Question

[woodchuck]

I have noticed that my truck won't warm up very well just left to idle. Then when i'm driving i noticed that the air will actually start blowing cooler when I stop at a stop light and then warm back up really quick when I take off. Is this normal for the 6.0s. Also does anyone know why the climate control says A/C when it is heating not cooling?

about the A/C mine dose the same when i turn the temp up for heat the direction changes to the floor but the A/C stays on till i manually hit the A/C button to turn it off...

you may be low on anti-freeze

[woodchuck]

It is below the antifreeze min mark but not terribly low.

top it off and see if that helps

I topped it off yesterday. Today when I got to work I saw something wet on the spring and suspension. I looked under the hood and found the degas bottle was well below the min level. Does the cap on those go bad like a radiator cap can? I didn't fill it above the max level and it was a cold engine.

find the leak and repair it.
