The Stovebolt Site Forums The Shop Area General Truck Talk Ice Inside cab?

I have a 58 half ton chevrolet and had removed the headliner.Got rid of the usual surface rust and painted with the rusty metal primer.I was in the truck on a cold morning with heavy frost on the cab top. With the heater starting to warm things up a bit I noticed the cab ceiling was all wet. The ice had formed inside the cab also and now melted water was just hanging there.Does this happen under the headliner and inside the doors also? If so what can be done to stop this other than parking inside

doesn't have to be "parked inside", but under something like a carport helps to keep the frost off - will mostly be a top problem, but can happen anywhere, part of why you had the "usual surface rust" to get rid of .... also usually helps to leave windows open so the interior isn't warmer than the outside of the sheet metal, to cause that condensation on the inside

It seems to me that you have a leak somewhere that collects in an unseen area, then condensates on the ceiling. The cowl area of these trucks are prone to rust. Debris falls into the open cowl intake vents in front of the windshield. The debris can get so bad that the entire area can be completely filled, causing rust holes into the cab, under the dash. This could have taken place many years ago, and cleaned out without noticing the rust holes.

That makes sense Bill. I would like to put a removable headliner in there just to be able to have a way to keep check under there from time to time.There was just as much frost inside the cab as it was on top.When it melted there were actually water droplets hanging over my head.

I suspect you had moisture buildup inside the cab from some source or another. Breathing, wet clothes/boots, leaks or something else. As the air cools (and the roof even faster) the water condenses out first on the coldest surface in the vicinity which is usually the roof (more exposed to the sky). parking under shelter will make all of the metal a more uniform temperature but the best solution is to reduce the moisture inside the cab. Find/fix any leaks, ventilate for the last part of the drive, if you have a heater setting it to cold air circulation with the windows part open will lower the moisture content available to condense and freeze. In short, all the same things you do to prevent snow melt from condensing and freezing on the inside of your windows in the daily driver.
